[0154] As already described, it is preferable that the first surface layer element comprises at least in part a material and / or is formed of such a material, which substantially corresponds to and / or can be connected to the plastic material in a material-fit manner.

[0155] For example, the material of the first surface layer element and the plastic material can be substantially the same material, and preferably, the first surface layer element and the plastic material can achieve and / or construct a connection that fits the material, thereby constructing or can construct a continuous and / or integral material body in the multilayer component.

[0156] Correspondingly, for example, it can be specified that the second surface layer element is partially or completely surrounded and / or covered by the first surface layer element and the core element.

[0157] Therefore, it can be preferably specified that the multi-layered component has at least:

[0158] - A first coating element and a second coating element, wherein one or both of the coating elements (correspondingly) have a first surface layer element and a second surface layer element.

[0159] - A core element disposed between a first cover element and a second cover element, and integrally connected to one or more first surface layer elements, such that each second surface layer element is partially or completely surrounded and / or covered by the corresponding first surface layer element and core element.

It is also understood that the reverse is also true.

[0175] It can be specified that the tool unit has at least two forming sections through which cavities can be constructed, which give the outer contour of the multi-layered component.

[0176] For example, the tool unit can be selectively moved between an open state and a closed state.

[0177] For example, it can be specified that, in the open state, the first coating element and the second coating element can be secured together at one of the forming sections.

[0178] For example, it can be specified that, in the closed state, plastic material can be introduced into the tool unit and preferably between the coating elements.

[0179] For example, the tool unit can be opened and / or closed in such a way that the forming sections can be spaced apart from each other and / or the forming sections can be engaged and / or in contact with each other.

[0180] For example, the tool unit can be opened and / or closed along the direction of operation.

[0181] For example, the direction of operation can be lateral and especially perpendicular to the direction of gravity or substantially parallel to the direction of gravity.

[0208] refer to Figures 1 to 5 A method for manufacturing a multilayer component 102 is provided, which can, for example, utilize... Figures 1 to 5 as well as Figure 8 The tool unit 100 shown in the figure, which is used to manufacture the multi-layer component 102, is used to perform the operation.

[0209] Preferably, the tool unit 100 may be included in and / or form part of a production equipment for manufacturing multilayer components 102.

[0210] Correspondingly, this method can also be implemented using the same production equipment.

[0211] A computer program product may also be provided, which includes instructions that, when implemented by a control unit and / or a computing unit, cause the control unit and / or computing unit to implement the method, for example, in the aforementioned production equipment.

[0212] Alternatively, a computer-readable storage medium may be provided on which the aforementioned computer program product is stored.

[0213] exist Figure 6 The diagram illustrates the possible transmission. Figures 1 to 5 Manufactured or produced by means of Figures 1 to 5 The multi-layer component 102 is manufactured by the method described above.

[0214] Multilayer component 102 may be configured for lightweight applications and / or for use in lightweight parts and / or lightweight components and / or lightweight structures, for example, for mounting.

[0215] The multilayer component 102 may be configured for a housing, such as a battery housing for an energy storage unit, particularly a battery, such as a rechargeable battery. For example, the multilayer component may be part of such a housing.

[0216] Multi-layer component 102 may be, for example, a chassis guard and / or at least a part thereof.

[0217] Especially in Figure 6 As can be seen, the multilayer component 102 has a first cladding element 104, a second cladding element 106, and a core element 108.

[0218] For example, the cladding elements 104 and 106 are configured as plate-like and / or plate-shaped.

[0219] The first coating element 104 has a first surface layer element 110 and a second surface layer element 112.

[0220] The second coating element 106 also has a first surface layer element 114 and a second surface layer element 116.

[0221] The first surface layer elements 110, 114 are preferably configured as elastic and / or plastically deformable and / or stretchable elements.

[0222] For example, the first surface layer elements 110, 114 are made of an elastic and / or plastically deformable and / or stretchable material and / or are made of or can be made of such material.

[0223] The first surface layer elements 110 and 114 are currently configured as thin film elements.

[0224] Alternatively, it may be conceivable that the first surface layer elements 110, 114 are constructed as sheet elements. In particular, it may be specified that the sheet elements of the first surface layer elements 110, 114 are plastic sheets, especially thermoplastic sheets and / or fiber composite sheets, especially organic sheets and / or strips and / or sheet elements formed from strips.

[0225] The film element of the first surface layer elements 110 and 114 is a plastic film element, such as a thermoplastic film element, currently a polyethylene film element or a PE film element.

[0226] The second surface layer elements 112 and 116 are preferably configured as bending-resistant rigid elements.

[0227] For example, the second surface layer elements 112, 116 have a flexural rigidity material and / or are made of or can be made of such material.

[0228] The second surface layer elements 112 and 116 are currently constructed as plate elements.

[0229] The plate components of the second surface layer elements 112 and 116 are metal plates, such as steel plates or plates containing aluminum; currently, they are steel plates.

[0230] The core element 108 has a plastic material 118 and / or is made of or can be made of plastic material 118.

[0231] In this embodiment, the plastic material 118 is preferably a thermoplastic material.

[0232] In the multilayer component 102, the first surface layer elements 110 and 114 are preferably arranged on the outer side.

[0233] The second surface layer elements 112 and 116 are arranged adjacent to the first surface layer elements 110 and 114.

[0234] The second surface layer elements 112 and 116 are arranged inside the multilayer component 102.

[0235] A core element 108 is arranged between the second surface layer elements 112 and 116.

[0236] Therefore, the core element 108 is arranged at least mostly inside the multilayer component 102.

[0237] The lateral edge regions of the core element 108 are exposed, for example, relative to the surface elements 110, 112, 114, 116.

[0238] In addition, the multi-layer component 102 has at least one secure section 120.

[0239] In this embodiment, the multilayer component 102 has multiple secure sections 120.

[0240] The Angu section 120 and the core element 108 are constructed as a single unit.

[0241] As can be seen in the figure, the second surface layer elements 112 and 116 have multiple through holes 122.

[0242] The mounting section 120 is constructed here in the region of the through hole 122 and is used to mount the second surface layer elements 112, 116 to the core element 108.

[0243] Especially in Figure 6 , Figure 7 and Figure 9 An exemplary embodiment of the multilayer component 102 is illustrated schematically.

[0244] Especially for reference Figures 1 to 6 In the method for manufacturing a multilayer component 102, a second surface layer element 112, 116 is first provided and is provided with a through hole 122.

[0245] For example, through-holes 122 are manufactured in the second surface layer elements 112, 116 by mechanical and / or thermal and / or abrasive methods. Mechanical methods may include, for example, drilling and / or punching. Thermal methods may include, for example, laser cutting or laser drilling and / or plasma cutting and / or gas cutting. Abrasive methods may include, for example, waterjet cutting.

[0246] Through holes 122 are configured, for example, to have regular and / or irregular spacing between each other.

[0247] The through holes 122 are configured, for example, to have regular and / or irregular spacing between each other and to be arranged in a matrix.

[0248] The through hole 122 is preferably constructed as circular and / or has a circular cross-section. Other shapes of the through hole 122 or other shapes of its cross-section are also conceivable, for example.

[0249] After the through-hole 122 is introduced into the second surface layer elements 112, 116, the first surface layer elements 110, 114 and the second surface layer elements 112, 116 are connected to each other accordingly and in association, thereby creating the first coating element 104 and the second coating element 106 respectively.

[0250] In particular, each of the second surface layer elements 112, 116 is connected to and currently overlaid with the first surface layer elements 110, 114.

[0251] For example, the second surface layer elements 112, 116 can be connected and, in particular, overlapped with the first surface layer elements 110, 114 by methods that may include, for example, an adhesive process and / or a temperature control process and / or a pressure application process.

[0252] For example, the first surface layer elements 110, 114 and / or the second surface layer elements 112, 116 may have at least one self-adhesive surface, particularly on one side, and / or adhesives and / or mortars may be applied to the first surface layer elements 110, 114 and / or the second surface layer elements 112, 116, particularly on one side, to connect the surface layer elements 110, 112, 114, 116 to each other.

[0253] Now, the first surface layer elements 110, 114 and the second surface layer elements 112, 116 are directly arranged and fastened to each other, thereby creating the first coating element 104 and the second coating element 106.

[0254] Now, before the first coating element 104 and the second coating element 106 are transferred into and arranged in the tool unit 100 for manufacturing multilayer components, the first coating element 104 and the second coating element 106 are conditioned and, in particular, pre-heated and / or preheated.

[0255] For example, this can be used to better connect the plastic material 118 to the covering elements 104, 106, and / or preferably simultaneously enable and / or benefit the forming in the tooling unit 100 during the introduction of the plastic material 118.

[0256] Preferably, the temperature regulation of the first coating element 104 and the second coating element 106 is achieved when the coating elements 104 and 106 are arranged and / or abutting each other.

[0257] Preferably, the second surface layer elements 112 and 116 face each other.

[0258] Therefore, the coating elements 104 and 106 were previously switched, for example, manually and / or automatically, to the above arrangement and / or to be in contact with each other.

[0259] Alternatively, the first coating element 104 and the second coating element 106 may be (optionally) temperature-controlled in a separate state, i.e. individually and / or separately from each other, wherein the coating elements 104, 106 are subsequently arranged and / or placed on each other, for example manually and / or automatically.

[0260] For example, temperature control can be achieved using a temperature control device, such as an oven, which can be part of and / or associated with the aforementioned production equipment.

[0261] After temperature adjustment, the first coating element 104 and the second coating element 106 are transferred into the tool unit 100 and introduced therein in a state where they are arranged and / or abutting each other.

[0262] The first coating element 104 and the second coating element 106 are introduced into the tool unit 100 in a horizontal or vertical orientation.

[0263] For example, the first coating element 104 and the second coating element 106 are introduced into the tool unit 100 in such a way that the gravity direction 124 is oriented substantially perpendicular to or substantially within the plane spanned by the main extension directions of the coating elements 104 and 106.

[0264] It is understood that the tool unit 100 is arranged in the production equipment in a manner corresponding to this orientation.

[0265] As in Figures 1 to 5 (as well as Figure 8 As can be seen from the diagram, the first coating element 104 and the second coating element 106 are introduced into the tool unit 100 in a vertical orientation in this embodiment.

[0266] Introducing, for example, involves placing and / or hooking and / or inserting the coating elements 104, 106 into the tool unit 100.

[0267] The introduction can be performed manually and / or automatically.

[0268] The tool unit 100 is introduced in a loaded state, in which the tool unit 100 is open, for example, in an open state (not shown in the figure).

[0269] Therefore, the first coating element 104 and the second coating element 106 are provided in the tool unit 100 in a state of arrangement and / or abutment against each other.

[0270] Here, each first surface layer element 110, 114 is arranged on the tool side, and each second surface layer element 112, 116 is arranged away from the tool unit 100, wherein the second surface layer elements 112, 116 of the covering elements 104, 106 are arranged facing each other and, for example, directly arranged and / or abutting each other.

[0271] like Figure 1 As shown, tool unit 100 is now closed and is therefore in the off state.

[0272] The first coating element 104 and / or the second coating element 106 are arranged adjacent to or directly on one or more tool elements 126 of the tool unit 100, and / or supported and / or held on one or more tool elements 126 of the tool unit 100.

[0273] In particular, the tool unit 100 has one or more tool elements 126 configured as positioning elements 128, preferably suspension pins and / or suspension mandrels, and / or separating elements 130, preferably separating pins.

[0274] The tool element 126, configured as a positioning element 128, is preferably used to position the coating elements 104 and 106 in the tool unit 100.

[0275] The tool element 126, configured as a separating element 130, is preferably used in the tool unit 100 to separate and / or space the coating elements 104, 106 from each other.

[0276] For example, the first coating element 104 and the second coating element 106 are directly arranged and / or supported and / or held at the tool element 126 configured as the positioning element 128.

[0277] For this purpose, through holes 132 are preferably constructed in the first surface layer elements 110 and 114, which correspond to the corresponding through holes 122 in the second surface layer elements 112 and 116, such that their longitudinal central axes are substantially coincident.

[0278] The through-holes 132 in the first surface layer elements 110, 114 can be provided, for example, in a separate method step as described above, and / or can be provided when the cover elements 104, 106 are arranged in the tool unit 100, for example by providing the positioning element 128 through the first surface layer elements 110, 114.

[0279] These correspondingly arranged through holes 122, 132 are used to receive tool element 126 configured as positioning element 128, which extends through these through holes 122, 132 for holding coating elements 104, 106 in tool unit 100 (see...). Figures 1 to 4 ).

[0280] Furthermore, the first coating element 104 and the second coating element 106 are placed and / or inserted into and / or hung thereon adjacent to the tool element 126 configured as a separate element 130 (see [link]). Figures 1 to 4 ).

[0281] The first coating element 104 and the second coating element 106 are preferably supported and / or held at the tool elements 126, 128, 130 in a form-fitting and / or force-fitting manner.

[0282] As already described, tool elements 126, 128, and 130 can therefore engage with through holes 122 and 132.

[0283] If it is still possible Figure 1 As can be seen, the positioning element 128 is arranged in the first forming section 134 of the tool unit 100, and the separating element 130 is arranged in the second forming section 136 of the tool unit 100.

[0284] Correspondingly, the tool unit 100 has two forming sections, here a first forming section 134 and a second forming section 136, through which a cavity 138 can be constructed, which essentially defines the outer contour of the multilayer member 102.

[0285] As already described, tool unit 100 can move between one or the open state and one or the closed state, wherein this is preferably achieved by spacing the forming sections 134, 136 apart from each other and then engaging the forming sections 134, 136 together again.

[0286] For example, tool unit 100 can be opened and / or closed along the operating direction 140 by means of an operating device not shown in the figure, to receive and / or open and / or close one or more tool units 100, which may be one or more parts of the production equipment.

[0287] For example, the operating direction 140 is lateral and, in particular, perpendicular to the direction of gravity 124.

[0288] Tool elements 126, 128, and 130 extend into cavity 138 to allow cladding elements 104 and 106 to be arranged therein.

[0289] Furthermore, tool elements 126, 128, and 130 can be moved into and / or removed from cavity 138.

[0290] In order to load tool unit 100 (see Figure 1 Tool elements 126, 128, and 130 are actively moved into cavity 138 by means of a traveling mechanism (not shown in the figure) of tool unit 100, or can be actively moved into cavity 138.

[0291] For example, the traveling mechanism is a pneumatic and / or hydraulic and / or electric traveling mechanism by means of which the tool elements 126, 128, 130 can be moved pneumatically and / or hydraulically and / or electrically.

[0292] Furthermore, tool elements 126, 128, and 130 can be actively removed from cavity 138 (see [reference]). Figure 5 This can be facilitated by the aforementioned marching mechanism.

[0293] After the first coating element 104 and the second coating element 106 are provided in the tooling unit 100, plastic material 118 is introduced and preferably injected and / or sprayed between the first coating element 104 and the second coating element 106 (see [link]). Figure 2 ).

[0294] This is preferably used for manufacturing the core element 108 of the multilayer component 102.

[0295] The injected and / or sprayed plastic material 118 is, for example, plastic material 118 heated to above the associated softening temperature and preferably melted, which is provided, for example, by means of a supply device of a production equipment or may be provided by means of a supply device of a production equipment.

[0296] In particular, this can be achieved by introducing injection molding.

[0297] As already described, the plastic material 118 is currently a thermoplastic material, such as polyethylene, polypropylene, polyphenylene ether, polyphthalamide, polyphenylene sulfone, polyetheretherketone, polysulfone, polyamide, polybutylene terephthalate, and / or polystyrene. In this embodiment, it is preferably polyethylene.

[0298] Especially in Figure 2 As can be seen, the plastic material 118 is injected and / or sprayed in via the inlet opening 142 of the tool unit 100, such as an injection nozzle and / or a spray nozzle.

[0299] The first coating element 104 here has through holes 122 and 132 corresponding to each other in the surface elements 110 and 114, through which plastic material 118 from the aforementioned introduction opening 142 of the tooling unit 100 is introduced or can be introduced between the coating elements 104 and 106, the introduction here being injection and / or spraying. The through holes 132 in the first surface element 110 are introduced in advance and / or in a separate method step in a manner already described, for example, together with other through holes 132 in the first surface elements 110 and 114.

[0300] In this case, the first coating element 104 and the second coating element 106 are spaced apart from each other during and / or by the injection and / or spraying of the plastic material 118.

[0301] Therefore, the arrangement and / or contact of the coating elements 104, 106 is transformed into a spaced-out state, which in Figure 2 As can be seen in the text.

[0302] In particular, the tool element 126, which is configured as a separating element 130, can achieve the separation of the coating elements 104 and 106 from each other.

[0303] Before injection and / or spraying, the separating element 130 travels toward the first coating element 104 and / or the second coating element 106 to partially fix and / or retain one of the first coating element 104 and / or the second coating element 106 in the tool unit 100, thereby enabling and / or causing the coating elements 104, 106 to be spaced apart from each other.

[0304] By allowing the plastic material 118 to reach between the coating elements 104 and 106 through the inlet opening 142 and through the through holes 122 and 132 in the first coating element 104, and by means of tool elements 126 and 130 (i.e., separation element 130), the first coating element 104 is fixed in the cavity 138, and the coating elements 104 and 106 are spaced apart from each other by the introduction of the plastic material 118.

[0305] For example, by supporting the first coating element 104 with the aid of tool elements 126, 130 (i.e., separation element 130) so as to partially fix and / or retain the coating element 104 in the tool unit 100, the second coating element 106 can be moved in the tool unit 100 by introduced, especially injected and / or sprayed plastic material 118 so as to space the coating elements 104, 106 apart from each other.

[0306] As from Figure 2As can be seen, the plastic material 118 is introduced into the cavity 138 through the inlet opening 142 in a direction opposite to the supporting force applied to the first coating element 104 by the tool elements 126, 130 (i.e., the separating element 130).

[0307] Due to the build-up and / or dominant introduction pressure in cavity 138 during the introduction of plastic material 118, the second coating element 106 moves toward the second forming section 136, such that coating elements 104, 106 are now spaced apart (see...). Figure 2 And plastic material 118 can be distributed therebetween to construct core element 108 (see Figure 3 ).

[0308] Therefore, the plastic material 118 injected and / or sprayed between the coating elements 104 and 106 constitutes the core element 108.

[0309] For example, the core element 108 is first constructed by injecting and / or spraying plastic material 118 between the coating elements 104, 106.

[0310] During the injection and / or spraying of the plastic material 118, the plastic material 118 is extruded through the through-holes 122 of the second surface layer elements 112, 116, and thereby introduced into contact between and / or with the respective first surface layer elements 110, 114 and the respective second surface layer elements 112, 116 (see...). Figure 5 ).

[0311] Thus, the plastic material 118 constructs corresponding fastening sections 120 in the regions of the corresponding through holes 122 of the second surface layer elements 112 and 116 (see...). Figure 5 ).

[0312] For example, this can preferably be done after the core element 108 is constructed by filling the gap 144 between the cladding elements 104, 106 and especially between the second cladding elements 112, 116 with plastic material 118 to fill the gap (see [link]). Figure 4 ).

[0313] The mounting section 120 is used to mount the first surface layer elements 110, 114 and / or the second surface layer elements 112, 116 at the core element 108.

[0314] In this case, in the multilayer component 102, the first surface layer elements 110, 114 are preferably arranged on the outside and / or pointing outwards.

[0315] For example, in a multilayer component 102, the first surface layer elements 110 and 114 are respectively the uppermost and lowermost layers.

[0316] Especially in Figure 5 As can be seen, the Angu section 120 and the second surface layer elements 112 and 116 form a shape-fitting connection.

[0317] In addition, the Angu section 120 is connected to the first surface layer elements 110 and 114 by means of shape matching and / or material matching.

[0318] The securing section 120 corresponds to and / or is associated with or may be associated with at least one through-hole 122, for example, through which plastic material 118 has been introduced between and / or into contact with the first surface layer elements 110, 114 and the second surface layer elements 112, 116. It is also conceivable that the securing section 120 corresponds to and / or is associated with or may be associated with two or more through-holes 122.

[0319] Preferably, the securing section 120 has at least one retaining area that is oriented laterally and, in particular, perpendicularly to the extension direction of the corresponding and / or associated and / or associated through-hole 122.

[0320] At least one retaining region is used to enable and / or enable a connection that mates with the shape of the second surface layer elements 112, 116 and / or with the shape of the first surface layer elements 110, 114 and / or with the material of the first surface layer elements 110, 114.

[0321] In this embodiment, the mounting section 120 and, for example, its retaining area are substantially configured as mushroom-shaped and / or mushroom-shaped and / or substantially riveted and / or riveted.

[0322] Preferably, after the plastic material 118 is introduced into the gap 144 between the first cover element 104 and the second cover element 106, and when the gap is filled with the plastic material 118, the securing section 120 and, for example, its retaining area, engage the second cover element 112, 116 from the rear with respect to the gap 144.

[0323] In this case, the Angu section 120 and, for example, its retaining area are arranged at least partially on and / or on the side of the second surface layer elements 112, 116 opposite to the gap 144.

[0324] As in Figures 1 to 5 As can be seen, the shape of the anchoring section 120 and, for example, its holding region is affected by and / or determined by the cavity 138 of the tool unit 100.

[0325] Cavity 138 has multiple cavity recesses 146, which essentially define the outer contour of the Securing section 120.

[0326] The cavity recess 146 is recessed in a direction that is transverse and particularly perpendicular to the longitudinal center plane of the cavity 138 of the tool unit 100.

[0327] Currently, the cavity recess 146 is recessed along the operating direction 140.

[0328] As already described, during the injection and / or spraying of the plastic material 118, the plastic material 118 is extruded through the through-holes 122 of the second surface layer elements 112, 116, thereby constructing corresponding secure sections 120 in the regions of the respective through-holes 122 of the second surface layer elements 112, 116 (see...). Figure 5 ).

[0329] In this case, in the region of the aforementioned through hole 122, the corresponding first surface layer elements 110, 114 are introduced into the cavity recess 146 by the plastic material 118, and are thereby stretched and / or plastically deformed into the cavity recess 146.

[0330] Therefore, one or more Angu sections 120 include sections of the first surface layer elements 110, 114 on the outer side.

[0331] Furthermore, in these areas, the plastic material 118 is connected to the first surface layer elements 110, 114 in one or more material combinations.

[0332] When cavity 138 and cavity recess 146 are filled with plastic material 118, preferably before the plastic material 118 has cooled and solidified, tool elements 126, 128, and 130 are preferably removed from cavity 138 by means of a travel mechanism already described (see...). Figure 5 ).

[0333] Due to the dominant jetting pressure of the plastic material 118 in the cavity 138, the volume released by the tool elements 126, 128, and 130 is also filled with the plastic material 118.

[0334] When the core element 108 and the anchoring section 120 are constructed, preferably sufficiently cooled and cured, the tool unit 100 can be switched back to the open state, so that the manufactured multilayer component 102 can be removed and / or taken out from the tool unit 100, for example, manually and / or automatically.

[0335] In the multilayer member 102, the first surface layer elements 110 and 114 of the cladding elements 104 and 106 are arranged on the outside and / or point outward.

[0336] In the multilayer component 102, the first surface layer elements 110 and 114 form the uppermost and lowermost layers.

[0337] In particular, in the multilayer member 102, the first surface layer elements 110, 114 form the outer surface of the multilayer member 102 and / or at least a portion thereof.

[0338] Subsequently, new coating elements 104, 106 can be provided in tooling unit 100 to manufacture another multilayer component 102.

[0339] refer to Figure 6 A multi-layer component 102 is provided, for example, a multi-layer component for a battery casing, which utilizes... Figures 1 to 5 Methods of manufacturing or can be used Figures 1 to 5 It is manufactured using this method.

[0340] and Figures 1 to 5 All structural and functional features related to the method can also be included Figure 6 In the multi-layered component 102, the characteristics, design schemes and advantages associated with it can also be included and implemented accordingly.

[0341] Especially in Figure 6 As can be seen, in the multilayer component 102, the first surface layer elements 110 and 114 are arranged on the outside and are exposed.

[0342] The first surface layer elements 110 and 114 are preferably used as protective elements for the multilayer component 102, for example, for corrosion protection.

[0343] The second surface layer elements 112 and 116 are arranged on the inside of the multilayer member 102 and are not exposed.

[0344] The second surface layer elements 112, 116 are preferably used as reinforcement and / or strengthening elements, for example, for load bearing and / or load distribution in the multilayer member 102.

[0345] refer to Figure 7 Multilayer components 102 are provided according to other exemplary embodiments, such as multilayer components for battery housings.

[0346] Figure 7 The embodiment of the multilayer component 102 is basically in line with Figure 6 The multi-layered components 102 are arranged and designed in the same way, and are basically made possible by... Figures 1 to 5 Methods of manufacturing or can be used Figures 1 to 5 The method used is to manufacture it, so only the differences will be described below.

[0347] for Figure 7 The multi-layer component 102 has through holes 122 punched in the second surface layer elements 112 and 116.

[0348] In this embodiment, when stamping the through hole 122, a hole flange 148 is constructed, for example, around the edge region of each through hole 122.

[0349] Along the stamping direction, each through hole 122 has, for example, a surrounding rounded corner region 150 in the upper edge region and a hole flange 148 in the lower edge region.

[0350] Furthermore, it can be used to manufacture or produce Figure 7 The tool unit 100 of the multi-layer component 102 has no cavity protrusion and / or cavity recess 146.

[0351] When the plastic material 118 is now introduced into the through hole 122, the through hole is filled, wherein the plastic material 118 reaches between the first surface layer elements 110, 114 and the second surface layer elements 112, 116 in the region of the rounded corner region 150 and forms the secure section 120 there.

[0352] As in Figure 7 As can be seen, the Angu section 120 and, for example, its retaining area are substantially constructed as mushroom-shaped and / or mushroom-shaped and / or substantially constructed as rivet-shaped and / or rivet-shaped.

[0353] In addition, each Anco section 120 is also joined from the rear to the corresponding second surface layer element 112, 116 and is connected in material matching with the corresponding first surface layer element 110, 114.

[0354] Furthermore, the inwardly pointing bore flange 148 can enable a reliable and / or stronger connection between the core element 108 and the second surface layer elements 112, 116.

[0355] refer to Figure 8 A method for manufacturing a multilayer component 102 according to other embodiments is provided.

[0356] Figure 8 The embodiments of the method are basically in line with Figures 1 to 5 The configuration and design are done in the same way, so only the differences will be described below.

[0357] However, Figure 8 The methods also include:

[0358] Cooling and / or allowing the introduced plastic material 118 to cool; and

[0359] The forming sections 134 and 136 are then moved away from each other to construct the foamed intermediate layer 152 of the multilayer component 102.

[0360] Cooling and / or allowing cooling to preferably only involve the edge side region of the core element 108 and the region arranged adjacent to the second surface layer elements 112, 116.

[0361] For example, the foamed intermediate layer 152 is arranged and / or constructed in the gap 144 and the core element 108.

[0362] For example, the foamed intermediate layer 152 is arranged and / or constructed along one or the longitudinal center plane of the cavity 138 of the tool unit 100.

[0363] As in Figure 8 As can be seen, the multilayer component 102 has such an intermediate layer 152, which is arranged between the cladding elements 104 and 106 and located in the core element 108.

[0364] The intermediate layer 152 is surrounded, in particular, by unfoamed plastic material 118 in the core element 108 above and below.

[0365] Therefore, the multilayer component 102 currently has three intermediate layers that form the core element 108.

[0366] The foamed intermediate layer 152 has, for example, a first material state, wherein the first material state is a foamed state and / or has a foam phase.

[0367] The corresponding intermediate layers above and below the foamed intermediate layer 152 have, for example, a second material state, wherein the second material state is a non-foamed state and / or substantially without a foam phase.

[0368] Furthermore, the first material state has a lower density than the second material state, and / or the second material state has a higher density than the first material state.

[0369] For example, it can be specified that there is a particularly continuous transition between the material states between the aforementioned intermediate layers with different material states. For example, in the continuous transition, the density can continuously increase or decrease, and / or the foam phase can continuously increase or decrease.

[0370] Alternatively or additionally, it may be specified that, upon introduction of the plastic material, the plastic material 118 is supplied with gas and / or a gas mixture and is thus foamed. For example, it may be specified in such a way that a particular material state, particularly the first material state already described, can be achieved. In this case, the forming sections 134, 136 do not need to move separately from each other.

[0371] refer to Figure 9 Multilayer components 102 are provided according to other exemplary embodiments, such as multilayer components for battery housings.

[0372] Figure 9The embodiment of the multilayer component 102 is basically in line with Figure 7 The multi-layered components 102 are arranged and designed in the same way, and are basically made possible by... Figure 8 Methods of manufacturing or can be used Figure 8 It is manufactured using this method.

[0373] Therefore, the current situation is Figure 7 and Figure 8 The combination of implementation methods can be referred to in other respects for the corresponding description.
