Description

FILTER ELEMENTS AND METHODS OF MANUFACTURING FILTER ELEMENTS FILTER Field of Invention This description refers to a filter element for filtering a fluid, more specifically to a filter element that can be inserted into a housing of a filter system and can be removed for handling. The description also refers to a method of manufacturing a filter element. Background of the Invention Filter elements, also called filter cartridges, are used for a wide variety of filtration applications. The fluid can be a liquid or a gas, including, for example, air. Indeed, in many cases, it is desirable to filter contaminants from a fluid stream using a filter element. For example, airflow streams to motor vehicle engines or power generation equipment, construction equipment, or other equipment, gas streams to gas turbines, and air streams to various combustion furnaces carry particulate contaminants. For such systems, it is preferable to remove the contaminants from the fluid or at least reduce their concentration. Ref. 330194 The filter element can be constructed as an element that must be removed and replaced from a filter system housing at regular time intervals or when the filtering performance has fallen below a critical threshold level. The filter element includes a filter media housing containing filter media. The filter media removes contaminants as the fluid flows through it. Commonly used and commercially available filter media include pleated or grooved media. Grooved media are also called Z-filter media. An example of a filter material envelope including grooved materials is described in U.S. Patent No. 7,396,376. The filter material envelope includes an outer circumferential face that forms a radial boundary of the filter material envelope. The outer circumferential face generally extends in a longitudinal direction from a first axial face to a second opposite face. The filter element includes, in addition to the filter media housing, a gasket arrangement to separate filtered from unfiltered fluid. Indeed, for the proper functioning of a filter element, it is essential that the filter media housing be properly sealed to the housing in which it is inserted. Various types of gasket arrangements have been proposed for a filter element. Typically, when pleated materials are used, for example, the gasket arrangement is made of expanded polyurethane (PU) obtained by a molding technique. Advantageously, the expanded PU gasket arrangement not only closes the pleats on the first axial face of the filter media housing, but a circumferential surface of the PU gasket arrangement can also be used as a radial or axial seal to ensure proper sealing to the housing. An end cap, generally also made of expanded PU, is used to close the pleats on the second axial face of the filter media housing. U.S. Patent No. 7,396,376 discloses an expanded polyurethane (PU) gasket arrangement used in combination with a ribbed filter media wrap. During the manufacturing process, the filter media wrap is placed in a mold along with a reinforcing frame element. The mold is then filled with PU, and through an upward process, an expanded PU overmold is formed. The reinforcing frame element provides strength to the gasket and also compensates for the irregular shape of the filter media wrap. However, one disadvantage of PU gasket arrangements is that they are less suitable for environments where temperatures can become high, for example, temperatures above approximately 80°C. Furthermore, due to the manufacturing process of expanded PU, the filter elements do not always have an aesthetically pleasing appearance. Alternatives to expanded gasket arrangements include gasket arrangements that incorporate mechanical seals, such as O-rings, which withstand higher temperatures and can be attached to the filter media housing, for example, via a gasket support. These alternative gasket arrangements may also utilize adhesives, such as glue, to bond a gasket support to the filter media housing. One disadvantage of using joint arrangements that include mechanical joints or arrangements involving the use of adhesives is that the manufacturing process may take longer, and joint arrangements involving multiple components may be less robust. The specific configuration of the gasket arrangement to be applied generally depends also on the type of filter material wrap used, and therefore a uniform manufacturing process for making a filter element is not always available. Therefore, it is desirable to provide more robust and cost-effective elements and to provide an improved process for manufacturing filter elements. Summary of the Invention One objective of this description is to provide a robust and cost-effective filter element for filtering fluids. An additional objective is to provide a method for manufacturing filter elements that is cost-effective and applicable to a variety of filter media casing types. In one aspect, this description describes a filter element that includes a filter material housing and a molded simple structure gasket arrangement. The filter material housing includes an outer circumferential face extending in a longitudinal direction and a first axial face transverse to the longitudinal direction. The molded simple structure gasket arrangement includes a gasket and a gasket support, wherein the gasket comprises a first material and the gasket support comprises a second material, and wherein the second material is different from the first material. The gasket support includes a first axial side, and the first axial side of the gasket support is heat-welded to at least a circumferential portion of the first axial face of the filter material housing. In another aspect, this description describes a filter element for placement in a filter system housing. The filter element includes a filter media housing for filtering a fluid and a gasket arrangement for separating filtered from unfiltered fluid when the filter element is operationally placed in the housing. The filter media housing includes an outer circumferential face extending in a longitudinal direction and a first axial face transverse to the longitudinal direction. The gasket arrangement includes a gasket made of at least one first material and a gasket support made of at least one second material, wherein the second material is different from the first material.The gasket is attached to the gasket holder, and this attachment is achieved by manufacturing the gasket assembly from the first and second materials using a multi-component injection molding process. The gasket holder includes a first axial side that is attached to at least a circumferential portion of the first axial face of the filter media housing by a heat-welding manufacturing process. In an additional aspect, this description outlines a method for manufacturing a filter element. The method includes: providing a filter material housing having a circumferential face extending in a longitudinal direction and a first axial face transverse to the longitudinal direction; providing a gasket support; and applying a heat-welding manufacturing process to couple a first axial side of the gasket support to at least a circumferential portion of a first axial face of the filter material housing. In some embodiments, the gasket arrangement includes a molded simple-structure gasket arrangement comprising a gasket and a gasket support.In some variations, the method also includes attaching the gasket to the gasket holder via a multi-component injection molding process. The gasket can be attached to the gasket holder before or after the heat welding process.

Detailed Description of the Invention In one respect, this description describes a filter element for mounting in a filter system housing. The filter element includes a filter media envelope in which the filter media traps particles and impurities present in an inlet fluid stream. The fluid can be a liquid or a gas, including, for example, air. When the filter element is mounted in the housing and the filter system is in operation, the filtered fluid should be kept separate from the unfiltered inlet fluid. Therefore, the filter element includes a gasket arrangement configured to separate the filtered fluid from the unfiltered fluid when the filter element is mounted in the housing and the filter system is in operation.The filter element can be constructed as an element that must be removed and replaced from a filter system housing at regular time intervals or when the filtering performance has fallen below a critical threshold level. In another aspect, this description outlines manufacturing methods for the filter elements. In some embodiments, this description describes filter elements manufactured by a production process involving a combination of multi-material injection molding and a heat-welding process. As further described herein, the multi-material injection molding process is used to form a gasket assembly comprising both a gasket support and a gasket, and the heat-welding process is used to bond the gasket support to the filter media housing. In some embodiments, the injection molding process of various materials is used to form both the gasket and the gasket support before the gasket support is bonded to the filter media casing using a heat-welding process. In such embodiments, the gasket, gasket support, and heat-welding process must each be designed so that the heat-welding does not damage the gasket or the filter media casing. In some embodiments, the injection molding process of various materials can be used to form the gasket support before joining the gasket support to the filter media wrap using a heat welding process and to form the gasket after joining the gasket support to the filter media wrap. Filter element With reference now to the figures, in which similar reference numbers illustrate similar or corresponding structures across the different views, examples of embodiments of a filter element 100 according to the invention are shown, for example, in Figure 1, Figure 2A, Figure 2B, Figure 5, Figure 6, Figure 7, and Figure 8. As illustrated in these figures, the filter element 100 includes a filter material housing 10, 110 and a gasket arrangement. In some embodiments, the gasket arrangement is preferably a molded, simple-structure gasket arrangement. The gasket arrangement is suitable for separating filtered from unfiltered fluid when the filter element 100 is operationally placed in a housing. As shown in Figures 1 through 10, the joint arrangement includes a joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e and a joint 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e. The joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e supports gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e, and, as further discussed below, gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e forms an interface between the filter media wrap 10, 110 and gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e. The joint 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e may, in some embodiments, be a circumferential joint. As will be illustrated in example embodiments discussed herein, the joint 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e may be an outward-facing radial joint, an inward-facing radial joint, or an axial joint. As further described herein, gaskets 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, and 1020a to 1020e are coupled to gasket holders 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, and 1040a to 1040e by a multi-material injection molding manufacturing process to form a molded simple-structure gasket assembly. The molded simple-structure gasket assembly may have visual indicators that it was formed by a multi-material injection molding manufacturing process, including, for example, visible feed points or visible ejector points. In some models, a crack (also known as a weld line) may be visible between joint 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e and joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e.The absence of a visible feed point, ejector point, or crack does not necessarily indicate, however, that the molded simple structure joint arrangement was not formed by a multi-material injection molding manufacturing process. The filter elements described herein are not limited to any particular filter material. For example, the filter elements described in the first aspect may include a filter material housing comprising grooved filter material, pleated filter material, or any other filter material suitable for filtering the fluid. Grooved filter materials may include wound grooved filter materials or stacked grooved filter materials.Although particular modalities are shown in the figures with a pleated filter material envelope 10 (see, for example, Figure 1, Figure 3, and Figure 4) or a grooved filter material envelope 110 (see, for example, Figure 5 to Figure 10), unless specifically noted, the teachings regarding a filter element 100 that includes a pleated filter material envelope 10 may be applied to a grooved filter material envelope 110, and the teachings regarding a filter element 100 that includes a grooved filter material envelope 110 may be applied to a pleated filter material envelope 10. Although several of the figures presented and discussed in this document specifically address the modes of a filter element for filtering a gas such as air, the filter elements described in this document are not limited to the filtering of any particular fluid.In some embodiments, the filter material may include a wet-deposited material. In some embodiments, the filter material may include a dry-formed or dry-deposited material. The filter material may include any suitable combination of materials selected by the expert, including, for example, polymers, fibers, binders, and additives. In one example embodiment, the filter material may include a wet-deposited nonwoven filter material comprising primarily cellulose fibers. In another example embodiment, the filter material may include a wet-deposited nonwoven filter material comprising cellulose and synthetic fibers, wherein the filter material comprises up to 10% or up to 20% synthetic fibers. In yet another example embodiment, the filter material may include a dry-deposited material comprising spunbonded synthetic fibers.Synthetic fibers bonded by spinning, for example, include polyester fibers. In another example embodiment, the filter material may include a multi-layered, dry-deposited material that includes synthetic fibers. Each of these materials may include, as noted above, additional binders and / or additives. The additional compounds may add functionality, including, but not limited to, flame retardancy, oleophobicity, and / or hydrophobicity. The filter material housing 10 or 110 includes at least i) an outer circumferential face 6 extending in a longitudinal direction Z and ii) a first axial face 7 transverse to the longitudinal direction. The longitudinal direction is indicated schematically in Figures 1 to 10 by a longitudinal axis Z. As further illustrated in Figures 3 and 9A to 9C, the first axial face 7 can be a side of the filter material housing that is transverse to the longitudinal direction defined by the longitudinal axis Z. This first axial face 7 can be an inlet or outlet side for the fluid. For the embodiments shown in Figures 3 and 9A to 9C, the two arrows indicate the direction of fluid inlet flow and fluid outlet flow.In other configurations, the fluid flow indicated in these figures may be reversed, depending on how the filter element is installed in the filter system housing. Filter element 100 can preferably be configured for placement in a filter system housing. When filter element 100 is operationally placed in the housing, the interface and / or interaction between gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e of filter element 100 and the housing prevents leakage during the separation of filtered fluid from unfiltered fluid by filter element 100. For the configurations shown, for example, in Figure 1 and Figure 5, the outer circumferential face 6 extends in the longitudinal Z direction from the first axial face 7 to a second axial face 8, opposite the first axial face 7. In these examples, the first and second axial faces 7 and 8 correspond to a fluid inlet and a fluid outlet, respectively. Depending on the specific shape of the filter media housing, and as illustrated schematically in Figure 9C, the filter media housing does not always include a second axial face that is parallel to the first axial face. In this example, the first axial face 7 is a flat outlet side for the filtered fluid, while the unfiltered fluid enters through a non-flat side of the filter media housing 10, such as, for example, a curved side. The gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, and 1020a to 1020e are made of at least one first material, and the gasket holder 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, and 1040a to 1040e are made of at least one second material. Generally, the second material is different from the first material. Examples of various materials that can be used for the gasket and gasket holder will be discussed below. When the filter element 100 shown in Figure 1 is placed in a housing of a filter system, the fluid passes through the filter material in a direction transverse to the longitudinal Z direction. For example, as illustrated by the arrows in Figure 3, the fluid to be filtered passes through the outer circumferential face 6 of the filter material housing 10 into the hollow filter body formed by the pleated materials, and the filtered fluid exits the filter material housing 10 through a central opening in the first axial face 7 of the filter material housing. This central opening in the first axial face 7 corresponds to the opening at the first end of the hollow filter body.Therefore, these types of modalities can include both an open-ended cap (which includes or consists of the gasket arrangement) and a closed-ended cap 70 at, respectively, the first and second ends of the hollow filter body formed by the folded filter material. The outer circumferential face 6 of the filter material envelope can have various shapes, and the description is not limited to any particular shape. In fact, the cross-section between the outer circumferential face 6 of the filter material envelope and a plane perpendicular to the longitudinal Z direction can be, for example, a circle, an oval, an ellipse, a rounded square (as shown in Figure 11A), an oblong shape, a rectangle, or any other shape suitable for a filter material envelope. Figure 8 shows a perspective view of a filter element 100 as an example, in which the cross-section of the outer circumferential face 6 with a plane perpendicular to the longitudinal Z direction is a rounded square. In some exemplary embodiments, the cross-section between the circumferential face 6 of the filter material envelope 10, 110 and a plane perpendicular to the longitudinal Z direction forms a circumferential outer perimeter having one or more convex parts. Two particular forms of a circumferential outer face 6 of the filter material envelope 10, 110 are shown in Figure 11B, where the upper figure illustrates a form having one convex perimeter part and the lower figure illustrates a peanut-like form having two convex perimeter parts. Figure 12A and Figure 12B show perspective views of filter material envelopes having a circumferential outer face 6 with one convex part. Although a grooved filter material envelope 110 is indicated in Figure 12, a pleated filter material envelope 10 could also be included in this configuration. In the configurations shown in Figures 5 through 8, the filter media housing 110 also has a second axial face 8, opposite the first axial face 7. This type of configuration is sometimes called a continuous flow configuration or a direct flow configuration. Generally, in this context, the filter media housing 110 of the filter element 100 includes an inlet face that allows unfiltered fluid to flow into the filter media housing 110 and an opposite outlet face that allows filtered fluid to exit the filter media housing 110. Therefore, the flow entering and the flow leaving the filter media housing are, in general, in the same continuous direction. In the configurations shown, for example, in Figures 1 through 8, the first axial face 7 and the second axial face 8 of the filter material housing 110 correspond to a fluid inlet face and a fluid outlet face, or vice versa. In general, the fluid inlet face and the fluid outlet face are flat, with the two faces parallel to each other. However, variations of this are possible, for example, non-planar faces. Figures 9A through 9C show cross-sectional views of example embodiments of filter elements 100 in which the filter media housing 110 includes a grooved filter media. The two arrows indicate example flow directions for fluid entering and exiting the filter media housing 110. Figure 9C shows an example in which the first axial face 7 is a flat side, but in which there is no second opposing flat axial face. In some embodiments, an outer surface of an outer layer of the wound grooved filter material may form the outer circumferential face 6 of the filter material wrap 110. Otherwise, a portion of the lining sheet of the grooved filter material discussed above forms the outer circumferential face 6. In some embodiments, the width of the first axial side 442a to 442f, 1042a to 1042e of the joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e can preferably be kept as small as possible so that the circumferential edge of the first axial face 7 that mates with the first axial side 442a to 442f, 1042a to 1042e is as small as possible. Indeed, since axial face 7 is an inlet or outlet for the fluid, the cover of the inlet or outlet on the first axial side 442a to 442f, 1042a to 1042e of the gasket support can influence the fluid flow and / or limit the filtering capacity of the filter media wrap 10, 110. In the embodiments shown, for example, in Figures 5 to 8, the filter elements 100 include a grooved filter material consisting of wound layers of grooved filter material. Each of the grooved filter material layers includes inlet grooves and outlet grooves oriented essentially parallel to the longitudinal Z direction of the filter material wrap. The groove inlets of the inlet grooves or the groove outlets of the outlet grooves of at least one outer layer of the wound layers of grooved filter material are blocked by the first axial side 1042a to 1042e of the gasket support 540, 640, 740, 840, 940, 1040a to 1040e.In some embodiments, the groove inlets of the inlet grooves or the groove outlets of the outlet grooves of at least the two outer layers of the wound layers of grooved filter material are blocked by the first axial side 1042a to 1042e of the gasket support 540, 640, 740, 840, 940, 1040a to 1040e. If the first axial face is an inlet face for receiving unfiltered fluid, then the inlet groove inlets are blocked by the first axial side 1042a to 1042e of the gasket support 540, 640, 740, 840, 940, 1040a to 1040e. On the other hand, if the first axial face 7 is an outlet face for removing the filtered fluid, then the outlets of the outlet grooves are blocked by the first axial side 1042a to 1042e of the gasket support 540, 640, 740, 840, 940, 1040a to 1040e. The filter element 100 is characterized by the use of two different manufacturing processes to manufacture the filter element 100, more specifically the manufacturing processes for attaching the gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e to the gasket holder 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e and the manufacturing process for attaching the gasket holder 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e to the filter material housing 10, 110. As further described herein, a multi-material injection molding manufacturing process is used to couple gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e to gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e and provides a molded simple structure gasket arrangement. As further described herein, a heat welding process is used to couple the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e to the filter media wrap 10, 110. In some embodiments, as shown in Figure 5 and Figure 9B, a support frame 60 can be attached to the second axial face 8. When the filter media housing 10, 110 is a grooved filter media housing 110, the support frame 60 can be configured to prevent the wound layers of the filter media housing 110 from moving in the longitudinal Z direction. Typically, the support frame 60 includes a protruding portion 62 that blocks the movement of the wound layers in the longitudinal direction. As further described herein, a second heat-welding process can be used to attach the support frame 60 to the filter media housing 10, 110. In some embodiments, as shown, for example, in Figure 6 and Figure 9A, the gasket support 640, 940 may include one or more projections 45 located in a plane essentially perpendicular to the longitudinal Z direction. When the filter media housing 10, 110 is a grooved filter media housing 110, the one or more projections 45 may be arranged and engaged on the first axial face 7 to prevent the wound layers from moving in the longitudinal Z direction. Advantageously, with these types of embodiments, it is not necessary to engage an additional support frame on the second axial face 8 of the filter media housing 10, 110, as is the case for embodiments such as shown in Figure 5 and Figure 9B. In embodiments such as shown, for example, in Figure 5 and Figure 6, the gasket support 540, 640 includes a radial circumferential side 41 extending in the longitudinal Z direction. The gasket 520, 620 surrounds this radial circumferential side 41 of the gasket support 540, 640, forming an outward-facing radial gasket. In one example embodiment, the gasket 520, 620 can be formed around the radial circumferential side 41 of the gasket support 540, 640. In some embodiments, as shown in Figure 7 and Figure 10E, gasket 720, 1020e is an axial gasket. To form an axial gasket, as illustrated in these figures, gasket 720, 1020e can be coupled to an opposing circumferential contour 44 of the gasket holder. As shown schematically in Figure 10E, the opposing circumferential contour 44 of the gasket holder 740, 1040e is generally a contour that is parallel to the circumferential contour 1042e of the gasket holder that is heat-welded to the first axial face 7 of the filter media housing 10. In these embodiments, as shown in Figure 10E, the circumferential contour 1042e and the opposing circumferential contour 44 correspond, for example, to two parallel rings. Various types of gasket supports 440a to 440f, 1040a to 1040e that are coupled to a filter media housing 10, 110 are illustrated schematically in Figures 4A to 4E and 10A to 10E. In these cross-sectional figures, which only partially illustrate the filter element 100, the gasket support 440a to 440f, 1040a to 1040e is represented by a dashed area and the filter media housing 10, 110 is represented by a dotted area. The gasket support 440a to 440f, 1040a to 1040e includes several sides that may differ from one type to another. As illustrated in these figures, the filter element 100 according to the first aspect of the description is characterized in that the gasket support 440a to 440f, 1040a to 1040e includes at least a first axial side 442a to 442f, 1042a to 1042e that is axially coupled with the first axial face 7 of the filter material housing 10.The first axial side 442a to 442f, 1042a to 1042e can be coupled to at least a circumferential portion of the first axial face 7 of the filter material housing by a heat-welding manufacturing process. Otherwise, the first axial side 442a to. 442f, 1042a to 1042e of the gasket support 440a to 440f, 1040a to 1040e may be a mating surface that is generally essentially parallel with the first axial face 7 of the filter media housing. The magnitude of the circumferential portion of the axial face 7 of the filter media housing that mats to the first axial side 442a to 442f, 1042a to 1042e of the gasket support may depend on the type of filter media housing 10, 110.For example, a filter material wrap 10 including a pleated material, as shown, for example, in Figure 1, Figure 3, and Figure 4, and a filter material wrap 110 including a grooved material, as shown, for example, in Figure 5 and Figure 8 to Figure 10, may have different circumferential parts of the first axial face 7 of the filter material wrap 10, 110 being covered by the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e. Similarly, only a portion of the first axial side 442a to 442f, 1042a to 1042e of the gasket support 440a to 440f, 1040a to 1040e can be a mating surface; i.e., only a portion of the first axial side 442a to 442f, 1042a to 1042e of the gasket support 440a to 440f, 1040a to 1040e can be mated with the first axial face 7 of the filter media housing. In some forms, as shown in the figure In Figure 10A to 10C, the gasket support 1040a to 1040e, represented by a dashed area, includes a tubular extension 43 extending in the longitudinal Z direction, thereby forming an inlet channel for receiving unfiltered fluid. In these embodiments, the gasket 1020a to 1020e is coupled to an outer circumferential surface of the tubular extension 43 to form an outward-facing radial gasket. The coupling of the gasket 1020a to 1020e to the outer circumferential surface of the tubular extension 43 can preferably be achieved by a multi-material injection molding process to obtain a molded, simple gasket arrangement. Examples of modalities with pleated filter materials In some forms, the filter element 100 includes a filter material wrap 10 which includes a pleated filter material. Figure 1 shows an exploded view of one embodiment of a filter element 100 according to the first aspect of this description. The filter material housing 10 of the illustrated filter element 100 includes pleated filter materials having a plurality of pleats arranged in a closed loop, in this example a ring, so as to form a hollow filter body extending in the longitudinal Z direction. The hollow filter body thus has a first opening and a second opening at, respectively, a first and a second end of the hollow filter body. The pleats are formed, for example, by folding a sheet of filter paper. In the embodiments shown in Figure 1, the hollow filter body is a hollow cylinder. A plurality of outer points of the plurality of pleats form an outer circumferential perimeter of the hollow filter body.In this modality, the outer circumferential face 6 of the filter material envelope 10 corresponds to this circumferential perimeter formed by the outer tips of the folds and the first axial face 7 and the second axial face 8 of the filter material envelope 10 correspond, respectively, to the first and second axes of the hollow filter body. In the embodiment shown in Figure 1 and Figure 4A, the gasket support 140, 440a only provides support for the gasket 120, 420a, but the first axial side 442a of the gasket support also provides an open-end cap for the first end of the hollow filter body. In effect, by attaching the first axial side 442a of the gasket support 140, 420a to the end of the hollow filter body by heat welding, the pleats of the filter media wrap 10 are closed at one end.As illustrated schematically in Figure 3, a closed-end cap can be further attached to the second end of the hollow filter body, thereby closing not only the pleats of the filter material wrap 10 at the second end but also completely closing the second opening at the second end of the hollow filter body so that the filtered fluid can only exit the filter element 100 through the first opening at the first end of the hollow filter body. In some embodiments, including when the pleated materials form a hollow filter body, as shown schematically in, for example, Figure 1 and Figure 3, the filter element 100 includes a closed-end cap 70. The closed-end cap 70 can be attached to a second axial face 8 of the filter material housing 10 by a second heat-welding manufacturing process. By using heat-welding to attach the closed-end cap 70 to the filter material housing 10 in addition to using heat-welding to attach the gasket arrangement to the filter material housing 10, the entire manufacturing process can be accelerated.By using two heat-welding manufacturing processes, no additional non-thermal welding manufacturing processes, such as molding or gluing, are required, which may require curing times or additional manufacturing apparatus to couple the filter material wrap 10 of a filter element 100 that includes a closed-end cap 70. In other embodiments in which the filter material envelope 10 includes pleated filter materials, an outer lining may be provided around the hollow filter body formed by the pleated filter materials, and in these embodiments, the outer lining forms the outer circumferential face 6 of the filter material envelope 10. Figures 4A through 4E show cross-sectional views of example gasket arrangements used in combination with a filter media housing 10 that includes pleated filter media. The reference W in the figures indicates the area where the first axial side 442a to 442e of the gasket support 440a to 440e is coupled to the first axial face 7 of the filter media housing 10 by heat welding. As discussed earlier, in embodiments that include a pleated filter media housing 10, the first axial face 7 can correspond to the first end of the hollow filter body formed by the pleated filter media. The example embodiments shown in Figure 1 and Figure 4A illustrate a filter element in which the gasket holder 140, 440a includes, in addition to the first axial side 442a, a radial circumferential side 41 that surrounds, or at least partially surrounds, the outer circumferential face 6 of the filter material housing 10. In some embodiments, as shown in Figure 1 and Figure 4A, the gasket 120, 420a can surround the radial circumferential side 41 of the gasket holder 140, 440a in order to form an outward-facing radial gasket; i.e., the gasket surface of the gasket 120, 420a is oriented outwards. The gasket 120, 420a can preferably be coupled to the radial circumferential side 41 of the gasket holder 140, 440a by a multi-material injection molding manufacturing process in order to form a molded simple structure gasket arrangement. Figure 4F shows a cross-sectional view of an embodiment in which gasket 420 surrounds the radial circumferential side 41 of gasket holder 440f to form an outward-facing radial gasket. In this embodiment, as illustrated schematically in Figure 4F, the cross-section of gasket holder 440f with a plane including the longitudinal Z-axis is T-shaped. In other embodiments, as illustrated in Figure 2B and Figure 4E, the gasket 220b, 420e of the gasket holder 240, 440e forms an axial seal. Specifically, in these embodiments, the gasket holder 240, 440e includes a second axial side 44 opposite the first axial side 442e, which engages the first axial face 7 of the filter media housing 10. The gasket 220b, 420e is attached to the second axial side 44 by a multi-material injection molding manufacturing process. In some embodiments, the radial circumferential side 41 of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e completely surrounds the outer circumferential face 6 of the filter material envelope 10, thereby forming a protective sheath around the filter material envelope 10. Figure 4B shows a cross-sectional view of part of an embodiment of a filter element 100 in which the gasket support 440b does not include a radial circumferential side circumscribing the outer circumferential face 6 of the filter media housing 10. Instead, in this embodiment, the gasket support 440b includes, in addition to the first axial side 442b, a tubular extension 43 that extends coaxially with the central opening at the first end of the hollow filter body. The tubular extension 43 thus forms an outlet channel for removing filtered fluid from the interior of the hollow filter body. As shown schematically in Figure 4B, in this example, the gasket 420b engages an inner circumferential surface of the tubular extension 43. In this way, an inwardly directed radial gasket is formed.The coupling of joint 420b to the inner circumferential surface of the tubular-shaped extension 43 can preferably be obtained by a manufacturing process of injection molding of various materials in order to obtain a molded simple structure joint arrangement. In Figure 4C, a similar embodiment to the embodiment in Figure 4B is shown in which the tubular-shaped extension 43 of the gasket support extends into the hollow filter body, instead of extending out of the hollow filter body as is the case with the embodiment shown in Figure 4B. In alternative embodiments, the tubular extension 43 of the gasket support 440a to 440f can form an inlet channel to carry unfiltered fluid into the hollow filter body so that the fluid can subsequently pass through the pleated materials. In additional embodiments having a joint support 440b as shown in Figure 4B, the joint 420b can also be coupled to an outer circumferential surface of the tubular-shaped extension 43 in order to form an outward-facing radial joint. Figures 2A and 4D show an additional embodiment in which the gasket 220a, 420d forms an inwardly directed radial gasket. In this embodiment, the gasket holder 240, 440d has a central opening configured to either expel filtered fluid or receive unfiltered fluid. In this embodiment, the gasket 220a, 420d can be coupled by the multi-component manufacturing process to an inner circumferential surface of the central opening of the gasket holder, thereby forming an inwardly directed radial gasket. In some embodiments, the filter material can be integrated at least 0.5 mm, at least 1 mm, at least 1.5 mm or at least 2 mm into the gasket support 140, 240, 340, 440a to 440f and / or the gasket support material 140, 240, 340, 440a to 440f can be impregnated at least 0.5 mm, at least 1 mm, at least 1.5 mm or at least 2 mm from the pleats of the filter material wrap 10. Examples of modalities with grooved filter materials In some embodiments, the filter element 100 includes a filter media wrap 110 which includes grooved filter media also known as Z-shaped filter media. With reference to the figures, Figure 5 shows an exploded view of one embodiment of a filter element 100 that includes a filter media housing 110 comprising grooved filter media. In the embodiment shown in Figure 5, an outer surface of the grooved filter media forms the outer circumferential face 6 of the filter media housing 110. Perspective views of various embodiments of filter elements in which the filter media housing comprises wound grooved filter media are illustrated in Figures 6 through 8. In some embodiments, grooved filter media may be formed by wound layers of grooved filter media. Each of these wound layers includes inlet grooves and outlet grooves oriented essentially parallel to the longitudinal Z direction. The groove inlets of the inlet grooves or the groove outlets of the outlet grooves of at least one outer layer of the wound layers are locked at the location where the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e engages with the first axial face 7 of the filter media housing 110.In some embodiments, the groove inlets of the inlet grooves or the groove outlets of the outlet grooves of at least the two outer layers of the wound layers are blocked by coupling the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e to the first axial face 7 of the filter material wrap 110. Additional cross-sectional views of example filter element configurations, including grooved filter media, are shown in Figures 9A through 9C. The two arrows in each of these figures indicate an example flow direction for the fluid. The gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, and 1040a to 1040e can be attached to the filter media housing 110 in any suitable configuration. Various examples of gasket supports 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e coupled to grooved filter media sleeves 110 are shown in Figure 10A to Figure 10C. In these cross-sectional views, the dashed and dotted areas represent, respectively, the gasket support 1040a to 1040e and the filter media sleeve 110. The reference W indicates a heat-welding area. Grooved filter media and filter media wraps, including grooved filter media with wound Z-shaped grooves, are disclosed by way of example in U.S. Patent Nos. 6,350,291 and 7,396,376 and European Patent Publication No. 3,680,002. One type of Z-shaped filter media construction uses two specific material components bonded together to form the material construction. The two components are a sheet of grooved material, typically corrugated, and a sheet of lining material. The lining material sheet is typically not corrugated. The grooved material sheet and the lining material sheet can be used to define materials having a set of parallel inlet grooves and a set of parallel outlet grooves.After attaching the grooved sheet together with the lining sheet, a layer of grooved filter material is obtained, and the grooved filter material includes the inlet groove set and the outlet groove set. By winding the layer of grooved filter material, a filter body is formed having an outer circumferential surface formed by an outer layer of wound grooved filter materials and having an axial inlet face for receiving unfiltered fluid and an axial outlet face for removing filtered fluid. The grooves in each of the wound layers are oriented essentially parallel to the longitudinal direction of the filter material wrap. As further described in U.S. Patents Nos. 6,350,291 and 7,396,376, with respect to Z-shaped filter materials, "wound" refers to a filter material wrap 110 formed by winding a strip of grooved filter material to form the filter material wrap 110.Such wound materials can be manufactured in a variety of shapes, including: round or cylindrical; oval, for example, like a racetrack; square; or rectangular with rounded corners; and the wound materials can even be configured in conical or similar arrangements. Examples of selected shapes are described in U.S. Patent No. 6,350,291. Additionally or alternatively, all or some of the grooved filter media may be stacked to create a filter media envelope. Stacked grooved filter media arrangements are described by way of example in U.S. Patents Nos. 5,820,646 and 8,292,983. For example, when the filter media envelope includes stacked grooved filter media, the outer circumferential surface of the filter body may be rectangular. In some embodiments, the outer circumferential surface of the filter body forms the outer circumferential face 6 of the filter media envelope 110. In other embodiments, a protective layer may be placed around the circumferential surface of the filter body such that the outer surface of the protective layer forms the outer circumferential face 6 of the filter media envelope 110. In the embodiments illustrated in Figures 5 to 8, the axial inlet and axial outlet of the filter body correspond to, respectively, the first axial face 7 and the second axial face 8 of the filter media envelope 110. Each layer of wound grooved material includes a set of inlet grooves and a set of outlet grooves. The inlet grooves are open on the axial inlet side of the filter body to receive the unfiltered fluid and are closed on the axial outlet side. Conversely, the outlet grooves are closed on the axial inlet side and open on the axial outlet side to allow the filtered fluid to exit the filter body. This forces the fluid to follow a Z-shaped path as it flows from the axial inlet to the axial outlet. In the embodiment shown in Figure 5 and Figure 10B, the circumferential portion of the first axial face 7 of the filter media housing 110 that is heat-welded to the first axial side 1042b of the gasket support 540, 1040b corresponds to a circumferential edge portion of the axial face 7 of the filter media housing 110. In general, this circumferential edge portion includes at least one axial side of the outer layer of the wound grooved filter media. Otherwise, at least the outer layer of the wound filter media cannot be used for filtration purposes. In some embodiments, not only the outer layer but one or more successive layers of the wound filter media may be sacrificed to allow for a more secure axial coupling between the first axial side 1042b of the gasket support and the first axial face 7 of the filter media housing. With further reference to Figure 5 and Figure 10, in some embodiments, the first axial side 1042a to 1042e of the gasket support 540, 1040a to 1040e, can be constructed as an axial circumferential contour. In effect, the portion of the first axial face 7 of the filter media housing 110 that mates with the first axial side 1042a to 1042e of the gasket support 540 can be kept as small as possible while still providing a secure fit to limit the reduction of fluid flow across the first axial face 7 of the filter media housing 110. Due to the axial coupling between the gasket support 540, 1040a to 1040e and the filter media wrap 110, the groove inlets of the inlet grooves or the groove outlets of the outlet grooves of at least one outer layer of the wound layers are blocked by the first axial side 1042a to 1042e of the gasket support. Preferably, to achieve a secure coupling between the gasket support 540, 1040a to 1040e and the filter media wrap 110, the groove inlets of the inlet grooves or the groove outlets of the outlet grooves of at least the two outer layers of the wound layers are blocked by the first axial side 1042a to 1042e of the gasket support 540, 1040a to 1040e. On the other hand, several successive layers that are blocked by the first axial side 1042a to 1042e of the gasket support 540, 1040a to 1040e should also be limited to ensure optimal operation of the filter element 100.When the filter material wrap 110 includes layers of wound grooved material, the number of successive layers that are blocked by the first axial side 1042a to 1042e of the gasket support 540, 1040a to 1040e should be less than ten layers, preferably less than eight layers, and more preferably less than six layers. The embodiments shown, for example, in Figure 6 and Figure 10A, illustrate filter elements 100 in which the gasket support 640, 1040a includes, in addition to the first axial side 1042a, also a radial circumferential side 41 that circumscribes the outer circumferential face 6 of the filter material envelope 110. In these embodiments, the gasket 620, 1020a surrounds the radial circumferential side 41 of the gasket support 640, 1040a in order to form an outward-facing radial gasket. In other embodiments, as illustrated in Figure 7 and Figure 10E, joint 720, 1020e forms an axial joint. Joint 720, 1020e can be coupled to a second axial side 44, opposite the first axial side 1042e, by a multi-material injection molding manufacturing process to form a molded simple joint arrangement as further described herein. As shown schematically in Figure 10E, the second axial side 44 of the joint support is, in general, a side that is parallel to the first axial side 1042e of the joint support 1040e. Figure 10B and Figure 10C show cross-sectional views of gasket arrangements in which the gasket support 1040b, 1040c includes a tubular extension 43 extending in the longitudinal Z direction, thereby forming an inlet channel for receiving unfiltered fluid. In such embodiments, the gasket 1020b, 1020c can be coupled to an outer circumferential surface of the tubular extension 43 to form an outward-facing radial gasket. The coupling of the gasket 1020b, 1020c to the outer circumferential surface of the tubular extension 43 can be achieved by an injection molding manufacturing process using various materials to obtain a gasket arrangement that is a molded simple joint arrangement. Figure 10A shows an embodiment in which the gasket support includes the tubular-shaped extension 43 and a radial circumferential side 41 that circumscribes the outer circumferential face 6 of the filter material wrap 110. This radial circumferential side 41 can serve as a protective surface for the filter material wrap 110. Figure 10D shows an embodiment in which the gasket 1020d forms an inwardly directed radial gasket. Specifically, in this embodiment, the gasket support 1040d is, for example, ring-shaped, and the gasket is positioned on an inner circumferential surface of the ring-shaped gasket support 1040d. In some embodiments that include wound grooved materials, as illustrated in Figure 5, the filter element 100 includes a support frame 60 coupled to the second axial face 8 of the filter material housing 10. This support frame 60 can be configured to prevent the wound layers from moving in a direction parallel to the longitudinal Z direction. In fact, during operation, due to fluid flow, the layers may begin to move in the longitudinal direction. As illustrated in Figure 5, the support frame 60 includes, for example, a circumferential contour 61 and a protrusion 62. The protrusion 62 can be positioned to block the movement of the wound layers along the longitudinal direction of the filter material housing. In some embodiments, the support frame 60 can be attached to the second axial face 8 of the filter media housing 110 by a second heat-welding manufacturing process, as further described herein. By using two heat-welding manufacturing processes, no additional non-thermal welding manufacturing processes, such as molding or gluing, are required, which might necessitate curing times or additional manufacturing equipment to attach the filter media housing 110 to a filter element 100 that includes a support frame 60. With reference to Figure 6, in some embodiments, the gasket support 640 may include one or more protrusions 45. The embodiment shown in Figure 6 includes one protrusion 45. If included, the one or more protrusions 45 may be arranged and coupled to the first axial face 7 of the filter media housing 110 to prevent the wound layers from moving in the longitudinal Z direction. The coupling of the one or more protrusions 45 to the first axial face 7 of the filter media housing 110 may preferably be achieved by heat welding, as further discussed herein. One advantage of the embodiment shown in Figure 6 compared to the embodiment shown in Figure 5 is that it does not require the attachment of an additional support frame 60 to the second axial face 8 of the filter material housing 110. Without wishing to be limited to theory, the inclusion of one or more projections 45 as an integral part of the gasket support 640 is expected to prevent overlapping of the materials. At the time of the invention, overlap was normally prevented by the inclusion of a support frame 60 attached to the second axial face 8. Therefore, if one or more projections 45 prevent overlapping of the materials without the addition of a support frame, a smaller plastic component can be included, making the filter element 10 cheaper and easier to manufacture. Materials for the gasket, gasket holder, and end cap The joint arrangement includes a joint 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e and a joint holder 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e. The gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e is made of at least one first material, and the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e is made of at least one second material. In general, the second material is different from the first material. In some versions, the gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e and / or the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e, can be manufactured from more than one material. Since the gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e prevents leakage during the separation of filtered fluid from unfiltered fluid by the filter element 100 when the filter element 100 is operationally placed in the housing and the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e must support the gasket and engage with the filter media wrap 10, 110, the gasket is normally formed from a softer material, examples of which are provided herein, and the gasket support is normally formed from a harder material. This document further describes examples of each of these materials. If filter element 100 includes a closed-end cap 70, the closed-end cap may be made of at least one other material. In some embodiments, the closed-end cap 70 may be made of more than one material. However, in some embodiments, the closed-end cap may preferably be made of the same material or materials as the gasket support. The use of the same material for the gasket support and the closed-end cap is expected to provide greater efficiency in the manufacture of filter element 100. In some embodiments, the transition temperature of the first material (or combination of materials) used to form the gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e may be higher than the transition temperature of the second material (or combination of materials) used to form the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e. Thus, when heat is applied to the joint arrangement during the heat welding manufacturing process, as further described herein, and the processing temperature is above the transition temperature of the second material, the joint is less likely to deform.The difference in transition temperature between the gasket materials and the gasket support can be selected by a skilled professional based on the geometry of the gasket arrangement, the heat source used, and the processing temperature. When the material or combination of materials includes a polymer fraction as a single phase in the amorphous state (including, for example, polystyrene (PS) or polycarbonate (PC)), the material's transition temperature is the mean temperature (Tmg) determined using differential scanning calorimetry (DSC) according to ASTM D341899, entitled Conventional Test Method for Polymer Transition Temperatures by Differential Scanning Calorimetry. The mean temperature (Tmg) is used as a proxy for the glass transition temperature (Tg) since Tg is, in practice, a temperature range. Any suitable instrument for performing DSC may be used; however, as an example, a DSC3+ (Mettler-Toledo AG, Schwerzenbach, Switzerland) with an FRS 6+ sensor may be used. When the material or materials include a semicrystalline polymer or any other material exhibiting more than one single polymer phase (including, for example, polypropylene (PP) or polyethylene (PE)), the material's transition temperature is the final temperature at which the elastic modulus (G') and the loss modulus (G'') intersect, when G' and G'' are plotted against temperature from 0°C to a temperature at which the polymer is in a molten state. G' and G'' are defined by ASTM D4092-01, entitled Conventional Terminology for Plastics: Dynamic Mechanical Properties. The increase in the tangent δ can be used to characterize a system transitioning to the melt flow region.In this document, G' and G'' are determined using dynamic mechanical temperature scanning (DMA) analysis per ASTM D444015, entitled Conventional Test Method for Plastics: Rheology in the Liquid State of Dynamic Mechanical Properties Using a Mechanical Spectrometer to Measure Forced Constant Amplitude Fixed Frequency Shear Oscillation, as further described in ASTM D4065-12, entitled Conventional Practice for Plastics: Dynamic Mechanical Properties: Determination and Reporting of Processes. Any suitable dynamic mechanical analyzer may be used; however, in one example configuration, a Q800 (TA Instruments, Newcastle, DE) may be used. In some embodiments, gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e is manufactured from at least one first material that includes any of the following non-limiting list of materials: a rubber, including an unsaturated rubber or a saturated rubber; a thermoplastic elastomer; a thermoset elastomer; a thermoplastic vulcanized material; or a mixture or combination thereof. Thermoplastic elastomers (TPEs), by way of example, include a polyamide TPE, a copolyester TPE, an olefinic TPE, a styrene TPE, a urethane TPE, or a dynamically vulcanized TPE, or a mixture or combination thereof. In some models, the material for forming the gasket can be selected based on the desired Shore hardness of the resulting gasket. In some embodiments, the joint has a Shore A value of at least 25, at least 30, at least 35, at least 40, at least 45, at least 50, at least 55, or at least 60. In some embodiments, the joint has a Shore A value of up to 40, up to 45, up to 50, up to 55, up to 60, up to 65, up to 70, up to 75, up to 80, up to 85, or up to 90. In one example embodiment, the joint has a Shore A value in the range of 30 to 90. In another example embodiment, the joint has a Shore A value in the range of 40 to 70. In yet another example embodiment, the joint has a Shore A value in the range of 50 to 70. In some embodiments, the Shore A value is determined as described in ASTM D224015el.The Shore A value of the gasket is preferably determined on the fully formed filter element - i.e., after coupling the gasket to the gasket holder and after heat-welding the gasket holder to the filter media wrap. Unlike U.S. Patent Publication No. 2009 / 0320424, which discloses the use of a soft urethane foam for a gasket forming an interface between a filter element and a filter housing to prevent unfiltered fluids from passing between the filter element and the fluid housing, the gasket disclosed herein is formed by an injection molding manufacturing process of various materials, as further described herein. Furthermore, U.S. Patent Publication No. 2009 / 0320424 shows that the Shore A value of the gasket is less than 25. Moreover, advantages in both manufacturing and use can be obtained when the gasket includes a thermoplastic polymer as described herein instead of a urethane gasket as described in U.S. Patent Publication No. 2009 / 0320424.Unlike a urethane gasket, which requires curing, a gasket formed from a thermoplastic polymer using a multi-material injection molding process does not require curing, increasing the efficiency of the manufacturing process. Furthermore, a gasket formed by a multi-material injection molding process can be stable at higher temperatures (e.g., up to 140°C) compared to a urethane gasket (which is typically stable only up to approximately 80°C), potentially providing greater stability during certain applications where the filter element 100 is exposed to heat. For example, some filter elements 100 installed in engine compartments may be exposed to temperatures exceeding 80°C (e.g., up to 90°C) during operation.

In some embodiments, as noted above, the joint support may include one or more 45 projections. If included, the one or more 45 projections may be formed from the same material or combination of materials as at least a part of the joint support.

Alternatively, in some embodiments, gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e and gasket holder 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e can each be formed by an injection molding manufacturing process, but gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e can be formed after coupling of gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e to the filter material wrap 10, 110 including, for example, by overmolding using an injection molding manufacturing process. Multi-material injection molding is the process of molding two or more different materials into a single, simple part. Multi-material injection molding can include, for example, multi-component injection molding, also called co-injection molding; multi-shot injection molding; and overmolding. In the multi-material injection molding process, at least one first material and one second material are used, wherein the gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e includes at least the first material and the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e includes at least the second material. In some embodiments, the multi-material injection molding manufacturing process may include the molding of only two materials, but in other embodiments, more than two materials may also be used. A variety of different permutations can be considered that use a multi-material injection molding manufacturing process to form a molded simple-structure joint arrangement. For example, when the multi-material injection molding manufacturing process includes two materials, the two different materials can be injected into a single mold to form a molded simple-structure joint arrangement. In this way, a molded simple-structure joint arrangement with two different material regions is obtained. The two different materials can be injected simultaneously (usually called multi-component injection molding or co-injection molding) or sequentially (usually called multi-shot injection molding) into a single mold.In one example embodiment, two different types of polymers can be used as the two components, wherein one polymer forms the gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e and the other polymer forms the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e or a portion thereof. Further examples of various materials and combinations of materials that can be used for the gasket and gasket support are discussed herein. Additionally or alternatively, overmolding may be used to form a molded simple structure joint arrangement in which one material is layered on top of another material. If overmolding is used to form joint 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e or a portion thereof, or joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e or a portion thereof, the overmolding is performed using an injection molding manufacturing process. Although overmolding with thixotropic or polyurethane gaskets is also possible, such methods are not performed using an injection molding manufacturing process. In some embodiments, the gasket assembly may include a third element made of a third material that differs from the first and second materials. This third element may be included in the gasket assembly in addition to the gasket and gasket support, or it may form, for example, only a portion of the gasket support (e.g., a portion of the gasket support that is not heat-welded to the filter media housing 10, 110). In such embodiments, a three-component injection molding manufacturing process may be used to form the gasket assembly. Alternatively, a two-component injection molding manufacturing process may be used to form a portion of the gasket assembly, and overmolding may be used to form the remainder of the gasket assembly. The use of multi-material injection molding allows for the formation and / or joining of gaskets 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e and gasket supports 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e without the use of a curable adhesive. Using a curable adhesive requires curing time, thereby increasing manufacturing time. Therefore, the use of multi-material injection molding allows for faster production of filter element 10. Furthermore, the use of multi-material injection molding instead of a curable adhesive such as polyurethane provides greater stability and dimensional stability to the gasket, resulting in less risk of leakage during use and providing more potential geometries and configurations for gasket placement and orientation. A filter media housing 10, 110 may be damaged, resulting in decreased efficiency, if exposed to the high temperatures required for injection molding of various materials. Therefore, in some embodiments, the gasket may preferably be attached to the gasket support and / or the gasket assembly may be formed by injection molding of various materials before heat-sealing the gasket assembly to the filter media housing 10, 110. Heat welding manufacturing process The heat-welding manufacturing process joins the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e and the filter media wrap 10, 110 using heat welding. In some embodiments, as noted above, the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e may preferably already be part of the gasket arrangement at the time of a heat-welding manufacturing process. Heat welding is also called plastic welding, thermal fusion, contact bonding, or direct bonding. In some embodiments, when the manufacturing method of filter element 100 includes two heat-welding manufacturing processes, the heat-welding manufacturing process may be a first heat-welding manufacturing process. The heat welding manufacturing process includes at least three stages as further described below. A first step includes providing a filter material envelope 10, 110 having an outer circumferential face 6 extending in a longitudinal direction Z and a first axial face 7 transverse to the longitudinal direction Z. As discussed above, the filter material envelope 10, 110 may include a pleated filter material or a grooved filter material or any other filter material suitable for filtering a fluid. A second stage includes providing a joint support. The gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e can be provided in the context of a gasket arrangement that includes a gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e, wherein the gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e is present in gasket support 140. 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e. In some embodiments, as further described herein, the joint arrangement is a molded simple structure joint arrangement formed by a multi-material injection molding manufacturing process. The joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e includes a first axial side 442a to 442f, 1042a to 1042e. A third step includes performing a heat-welding manufacturing process to couple the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e to at least a circumferential portion of the first axial face 7 of the filter material housing 10, 110. Any suitable heat welding manufacturing process may be used. Examples of heat welding processes include contact heating; hot air welding; hot gas welding; induction heating (i.e., heating with high-frequency electromagnetic waves); laser welding; mirror welding; vibration welding; rotary rubbing welding; infrared welding; and friction welding, which includes, for example, ultrasonic welding. In some embodiments, a combination of different heat welding processes may be used. In one example embodiment, described in the examples, a heating plate is used to heat the joint support. In some forms, the heat welding manufacturing process uses a heat welding process or heat source that only locally heats the joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e. More specifically, the heat welding manufacturing process can preferably heat only the first axial side 442a to 442f, 1042a to 1042e of the joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e or a portion of the first axial side 442a to 442f, 1042a to 1042e in such a way that other elements or other sides of the joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e do not deform or begin to melt. It is particularly preferred that, if present, gasket 120, 220a, 220b, 320, 420a to 420f, 520, 620, 720, 820, 920, 1020a to 1020e does not deform during heating of gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e. In some embodiments, the first axial side 442a to 442f, 1042a to 1042e can be heated until a given layer thickness of the first axial side, a portion of the first axial side, or a specific volume of the first axial side becomes deformable. In some embodiments, a thickness of at least 0.5 mm, at least 1 mm, at least 1.5 mm, or at least 2 mm of the first axial side becomes deformable. In some embodiments, a thickness of up to 2 mm, up to 3 mm, up to 4 mm, or at least 5 mm of the first axial side becomes deformable.In this way, when the at least circumferential part of the first axial face 7 of the filter material wrap 10, 110 is pressed towards the first axial side 442a to 442f, 1042a to 1042e, the at least circumferential part of the first axial face 7 of the filter material wrap 10, 110 enters at least 0.5 mm, at least 1 mm, at least 1.5 mm or at least 2 mm into the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e. In some embodiments, performing a manufacturing process by heat welding may include the sub-steps: first, heating the first axial side 442a to 442f, 1042a to 1042e of the joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e until at least a portion of the first axial side 442a to 442f, 1042a to 1042e becomes deformable. Secondly, join the filter material wrap 10, 110 with the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e so that at least a circumferential portion of the first axial face of the filter material wrap 10, 110 is pressed towards the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e.And, thirdly, allow the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e to cool so that the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e is securely joined with at least a circumferential portion of the first axial face 7 of the filter media wrap. The processing temperature required for heat welding depends on the specific material chosen for the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e or the part of the gasket support that is to be joined to the filter media wrap 10, 110. The processing temperature is the temperature at which the first axial side portion 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e intended to be joined to the filter media wrap 10, 110 becomes deformable. When the gasket support is formed from the same material or combination of materials throughout its volume, the processing temperature is the temperature at which the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e becomes deformable. The processing temperature is measured by measuring the temperature of the surface portion of the first axial side 442a to 442f, 1042a to 1042e of the joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e that is heated. The processing temperature is preferably higher than the transition temperature of the material forming the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e or forming the part of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e intended to be joined to the filter material wrap 10, 110. As further discussed herein, when gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e, or a portion thereof, includes a polymer fraction as a single phase in the amorphous state (including, for example, polystyrene (PS) or polycarbonate (PC)), the transition temperature of the material is the mean temperature (Tmg) determined using differential scanning calorimetry (DSC) according to ASTM D341899, entitled Conventional Test Method for Polymer Transition Temperatures by Differential Scanning Calorimetry. The mean temperature (Tmg) is used as a representation of the glass transition temperature (Tg) since Tg is, in practice, a temperature range. Any instrument suitable for performing DSC may be used. However, in one example configuration, a DSC3+ (Mettler-Toledo AG, Schwerzenbach, Switzerland) with an FRS 6+ sensor can be used. When the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e, or a portion thereof, includes a semicrystalline polymeric material or any other material having more than one single polymeric phase (including, for example, a polypropylene (PP) or a polyethylene (PE)), the transition temperature of the material is the final temperature at which the elastic modulus, measured in shear (G'), and the loss modulus, measured in shear (G''), intersect when G' and G'' are plotted against temperature from 0°C to a temperature at which the polymer is in a molten state. The increase in the tangent δ can be used to characterize a system transitioning to the melt flow region. G', G'' and the tangent δ are defined by ASTM D4092-01, entitled Conventional Terminology for Plastics: Dynamic Mechanical Properties.In this document, G' and G'' are determined using dynamic mechanical temperature scanning (DMA) analysis per ASTM D4440-15, entitled Conventional Test Method for Plastics: Rheology in the Liquid State of Dynamic Mechanical Properties Using a Mechanical Spectrometer to Measure Forced Constant Amplitude Fixed Frequency Shear Oscillation. Any suitable dynamic mechanical analyzer may be used; however, in one example configuration, a Q800 (TA Instruments, Newcastle, DE) may be used. The preferred processing temperature may be selected by a person skilled in the art with reference to the transition temperature of the gasket, the transition temperature of the material forming the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e or the part of the gasket support to be joined to the filter material wrap 10, 110, the heat welding method used and the configuration of the gasket arrangement. In some embodiments, the processing temperature may be at least 5°C, at least 10°C, at least 15°C, at least 20°C, at least 25°C, at least 30°C, at least 35°C, at least 40°C, at least 45°C, or at least 50°C higher than the transition temperature of the second material. In some embodiments, the processing temperature may be up to 50°C, up to 75°C, up to 100°C, up to 125°C, up to 150°C, up to 175°C, or up to 200°C higher than the transition temperature of the second material. In some configurations, the processing temperature may be at least 100°C, at least 125°C, at least 150°C, at least 175°C, or at least 200°C. In some configurations, the processing temperature may be up to 200°C, up to 225°C, up to 250°C, up to 300°C, up to 325°C, or up to 350°C. In one example configuration, the processing temperature may be in the range of 100°C to 300°C. In another example configuration, the processing temperature may be in the range of 150°C to 300°C. In yet another example configuration, the processing temperature may be in the range of 200°C to 300°C. In some embodiments, the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e is securely joined with at least a circumferential portion of the first axial face 7 of the filter material housing when the joint prevents leakage during separation of filtered fluid from unfiltered fluid by the filter element 100. In some embodiments, including when the filter media wrap 10, 110 is a pleated filter media wrap 10, the filter media wrap 10 can be securely bonded when the filter media is embedded at least 0.5 mm, at least 1 mm, at least 1.5 mm, or at least 2 mm into the gasket support 140, 240, 340, 440a to 440f and / or when the gasket support material 140, 240, 340, 440a to 440f is impregnated at least 0.5 mm, at least 1 mm, at least 1.5 mm, or at least 2 mm into the pleats of the filter media wrap 10. That is, the end portions of the pleats are closed by the incorporation of the material from the first axial side 442a to 442f, 1042a to 1042e of the support. gasket 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e that impregnates the filter material. In some embodiments, including when the filter media wrap 10, 110 is a wound grooved filter media wrap 110, the filter media wrap 110 can be securely bonded when at least one layer of grooves is fully integrated into the gasket support 540, 640, 740, 840, 940, 1040a to 1040e and / or the gasket support material 540, 640, 740, 840, 940, 1040a to 1040e impregnates at least one layer of grooves.Without wishing to limit ourselves to theory, although it is thought that the integration of at least one layer of grooves into the gasket support 540, 640, 740, 840, 940, 1040a to 1040e is sufficient to prevent leakage during the separation of filtered fluid from unfiltered fluid by the filter element 100, in some embodiments it may be desirable to integrate additional layers of grooves into the gasket support 540, 640, 740, 840, 940, 1040a to 1040e, or to integrate partial layers of grooves into the gasket support 540, 640, 740, 840, 940, 1040a to 1040e, or both, to increase the strength of the bond between the filter media housing 110 and the gasket support 540, 640, 740, 840, 940, 1040a to 1040e. In an example embodiment, shown in Figure 6, the bond strength between the filter material sleeve 110 and the gasket support 640 can be increased by including a projection 45 that is pressed towards the first axial face 7 of the filter material sleeve 110.Additional arrangements may also be considered in which a 45 projection does not extend across the width of the first axial face 7 of the filter material housing 110. For example, multiple 45 projections, which may or may not extend across the width of the first axial face 7, could be positioned around the circumference of the first axial face 7. When the 45 projections do not extend across the width of the first axial face, the projections could form a configuration similar to the markings on an analog clock. When the filter element 100 includes one or more 45 projections, heating the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040, may also include heating the 45 projection(s) until it becomes deformable. Furthermore, during the second stage of joining the circumferential edge of the first axial face 7 of the filter material wrap 10, 110 with the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040, the projection 45 can be simultaneously pressed towards the first axial face 7. In some embodiments, a heat-welding manufacturing process may also include heating at least a portion of the filter material wrap 10, 110 before joining the filter material wrap 10, 110 with the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e. Without wishing to limit ourselves to theory, it is thought that heating at least a portion of the filter media wrap 10, 110 before joining the filter media wrap 10, 110 with the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e may improve the bond, since contact with the filter media wrap 10, 110 does not decrease the temperature—and therefore the deformability—of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e as dramatically or rapidly, resulting in a stronger bond between the two materials.In one example embodiment, the filter media wrap 10, 110 can be heated to the same temperature as the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e before joining the filter media wrap 10, 110 with the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e. Whether and to what extent at least part of the filter material housing 10, 110 should be heated can be determined by an expert based on the composition of the filter material housing 10, 110. For example, some materials, including filter materials that include synthetic components, may deform if heated or if heated above a certain temperature before contacting the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e. In practice, when the filter media housing 10, 110 is joined with the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040 such that at least the circumferential portion of the first axial face 7 of the filter media housing 10, 110 is pressed against the first axial side 442a to 442f, 1042a to 1042e of the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040, a relative movement occurs between the filter media housing 10, 110 and the support. gasket 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040. There are several options for performing this relative movement. For example, the filter media wrap 10, 110 can be held in a fixed position while the gasket support is moved 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040.The gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040 can preferably be moved in a direction parallel to the longitudinal Z axis of the filter media wrap 10, 110. In alternative embodiments, the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040 can be held in a fixed position and the filter media wrap 10, 110 can be moved. Furthermore, it can be considered that both the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040 and the filter media wrap 10, 110 may be movable. The component that is held in a fixed position may be retained in that position by any suitable means, including, for example, a vacuum, a clamp, etc. Without limiting ourselves to theory, it is believed that using a heat-welding manufacturing process to join the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e and the filter media wrap 10 offers several advantages over, for example, using an adhesive material such as glue, molten metal, Sikaflex® (Sika, AG), and / or polyurethane (PU). Firstly, using a thermoplastic for the gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e can provide greater temperature resistance than adhesive materials such as PU. Secondly, the use of a heat welding manufacturing process can improve manufacturing speed since no curing time is required.Finally, the use of a thermoplastic for the gasket support can increase the filter element's ability to be recycled; for example, by overheating, gasket support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e could remove the filter material wrap. 10, and recycle the components separately. Second manufacturing process by heat welding When the filter element 100 includes a support frame 60, the coupling of the support frame 60 to the second axial face 8 can be achieved by a second manufacturing process by heat welding. The second heat welding manufacturing process is a process that is similar to the first heat welding manufacturing process but replaces the support frame 60 with the joint support 140, 240, 340, 440a to 440f, 540, 640, 740, 840, 940, 1040a to 1040e. The second heat-welding manufacturing process includes heating the support frame 60 or a portion thereof until a temperature is reached at which the support frame 60 or a portion thereof becomes deformable; joining the filter media wrap 10, 110 and the support frame 60 so that the second axial face 8 of the filter media wrap 10, 110 is pressed into the support frame 60 or a portion thereof; and allowing the support frame 60 or a portion thereof to cool so that the support frame 60 is securely joined to the second axial face 8 of the filter media wrap 10, 110.

EXAMPLES All reagents, starting materials, and solvents used in the following examples were purchased from commercial suppliers (such as Sigma Aldrich, St. Louis, MO) and were used without further purification unless otherwise noted. Heat welding method An end cap (also referred to herein as a gasket holder), with or without a gasket, is placed in a mount and held in place by a vacuum. A filter media sleeve is placed in another mount. The heat source (a heating plate) is set to 350°C and is located between the end cap and the filter material wrap (Figure 13A). 111 The end cap is pressed against the heating plate for 20 seconds (Figure 13B). Optionally, depending on the distance between the filter media wrap and the heating plate, the heating plate also heats the filter media wrap. The end cap lifts off the heat plate and the heat plate is removed. The end cap is moved towards the filter media envelope (indicated by the arrows in Figure 13C) at a fixed speed (1 mm / s and 3 mm / s were tested) and for a fixed distance (e.g., 1.5 mm). Once the fixed distance is reached, the end cap is then held in place for 15 seconds (Figure 13D). The resulting joined parts are removed from the mounts. Example 1 This example describes the fusion of a folded cellulose material with a joint support. Using the method described above and as shown in Figure 13, a folded material wrap was fused to a gasket support made from the homopolymer Polystone® P (Röchling Engineering Plastics, Germany). The filter material wrap was also heated by a hot plate to a temperature in the range of 100°C to 200°C (preferably 100°C to 150°C). 112 example results are shown in Figure 14. The filter material is integrated approximately 1 mm into the gasket support. Example 2 This example describes the fusion of a synthetic ribbed material with a joint support. Using the method described above, a grooved material wrap was fused to a gasket support fabricated from the homopolymer Polystone® P (Röchling Engineering Plastics, Germany). The filter material wrap was either not heated or only very slightly heated by the hot plate before fusion. Example results are shown in Figure 15. Approximately two layers of grooves were integrated into the gasket support at the location indicated by the arrow in Figure 15A.
