[0002] In vehicles, bright trim strips are frequently used to enhance the product's aesthetics and perceived luxury. However, these strips, due to the specialized processing and manufacturing techniques required for their production, are prone to damage and are expensive. Furthermore, while black bright trim strips are gaining market acceptance, their surface is susceptible to optical distortion. Therefore, bright trim strips in these technologies are easily damaged, impacting the overall aesthetics of the vehicle. Summary of the Invention

[0004] The first aspect of this application provides an edge-wrapping assembly consisting of a decorative layer and edge-wrapping parts. The decorative layer is obtained from polyurethane injection molding material. Polyurethane injection molding material has sufficiently low viscosity and high fluidity, resulting in low injection pressure, and can be applied as a surface coating to the surface of the edge-wrapping parts.

Detailed Implementation
[0053] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
[0054] Unless otherwise stated or in case of conflict, the terms or phrases used in this application shall have the following meanings:
[0055] In this application, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0059] In related technologies, it is difficult to achieve a high-gloss black finish on the surface of edge banding components without a glossy trim. If a glossy trim is used, its molding process limits the diversity of appearance designs. Furthermore, the molding process of the glossy trim restricts the dimensional accuracy of the product; integral injection molding with the edge banding component easily produces burrs, and subsequent trimming can easily scratch the surface of the glossy trim. Additionally, if the edge banding component is too thick, it is prone to shrinkage and deformation, which in turn stretches the surface of the glossy trim, causing optical distortion and affecting the product's aesthetics. Therefore, this application uses a decorative layer instead of the glossy trim in related technologies, which not only improves the product's aesthetics but also allows for greater versatility and reduces costs.

[0061] This embodiment provides an edge-sealing assembly 1, applied to a vehicle, the vehicle including a window glass 2, the edge-sealing assembly 1 including an edge-sealing component 11 and a decorative layer 12 disposed on one side of the edge-sealing component 11, the edge-sealing component 11 being used to wrap the window glass 2, the decorative layer 12 being used to decorate the vehicle, the decorative layer 12 being obtained from polyurethane injection molding material through an injection molding process.
[0062] The edge-sealing assembly 1 provided in this embodiment includes an edge-sealing component 11 for wrapping the vehicle window glass 2. The material of the edge-sealing component 11 includes at least one of PU, PVC, and TPE. The edge-sealing component 11 is obtained by injection molding. The shape of the edge-sealing component 11 is adapted to the shape of the vehicle window glass 2. The vehicle window glass 2 can be a windshield, a side window, a corner window, a rear windshield, or a sunroof, etc. Optionally, the edge-sealing component 11 includes a first edge-sealing portion 111 and a second edge-sealing portion 112 connected to the first edge-sealing portion 111, wherein the first edge-sealing portion 111 is used to wrap the vehicle window glass 2. Optionally, the second edge-sealing portion 112 is used to overlap the vehicle body fittings.
[0063] The hardness of the edging component 11 is less than the hardness of the decorative layer 12. Optionally, the hardness of the edging component 11 is 50A-95A. Optionally, the Shore hardness of the decorative layer 12 is 80D-60A. For example, the Shore hardness of the decorative layer 12 can be 80D, 100D, 20A, 30A, 40A, 50A, or 60A, etc.
[0064] The edge-wrapping assembly 1 provided in this embodiment also includes a decorative layer 12 for decorating the vehicle. The decorative layer 12 is obtained from polyurethane injection molding material through an injection molding process. Optionally, the polyurethane injection molding material includes at least one of polyurethane (PUR) and polyurea (PUA). Optionally, the polyurethane injection molding material is liquid. The decorative layer 12 allows light to pass through; or the decorative layer 12 has a specific color that blocks light. The decorative layer 12 can be disposed on the exterior of the vehicle as an exterior decoration. The decorative layer 12 can also be disposed on the interior of the vehicle as an interior decoration.
[0065] In one implementation, such as Figure 5 As shown, along the stacking direction from the edge banding 11 to the decorative layer 12, the thickness T of the decorative layer 12 satisfies the following condition: 0.2mm≤T≤2mm.
[0066] For example, the thickness T of the decorative layer 12 can be 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, or 2mm, etc. By limiting the thickness of the decorative layer 12 to 0.2mm-2mm, this embodiment can achieve a thinner, high-gloss surface while reducing production costs.
[0067] Polyurethane injection molding material has sufficiently low viscosity and high fluidity, resulting in low injection pressure, making it suitable as a surface coating for the surface of the edging part 11. The resulting decorative layer 12 exhibits a typical high gloss, stunning 3D depth, and a luxurious appearance. The surface of the decorative layer 12 itself is smooth and glossy, enhancing its visual appeal and improving the vehicle's aesthetics, satisfying consumers' pursuit of a high-quality, perfect appearance. Furthermore, the decorative layer 12 does not require additional polishing, reducing production costs and increasing production efficiency.
[0068] In addition, polyurethane has self-healing properties. If the decorative layer 12 is scratched due to careless use, the self-healing effect of polyurethane can provide additional protection for the surface of the decorative layer 12, ensuring that the surface of the decorative layer 12 always maintains a perfect appearance and greatly improving scratch resistance.
[0069] Furthermore, the high hardness of polyurethane material can act as a plastic skeleton, increasing the dimensional stability of the edge-wrapping component 1; it can not only prevent the product edge-wrapping component 11 from collapsing under pressure, but also prevent problems such as light distortion on the outer surface of the decorative layer 12 after pressing and rebounding.
[0070] Therefore, this embodiment provides a decorative layer 12 made of polyurethane injection molding material on the edge-binding component 11, which facilitates processing and production, eliminates the need for glossy trim strips used in related technologies, reduces production costs, and improves product aesthetics. Furthermore, the decorative layer 12 has high hardness, which can overcome the shrinkage problem caused by the edge-binding component 11, enhance the dimensional stability of the edge-binding assembly 1, effectively avoid the problem of light distortion on the surface of the black glossy trim strip, and effectively improve the durability of the edge-binding assembly 1.
[0071] Please refer to this as well. Figures 3-8 In one embodiment, the edging member 11 includes a first edging portion 111 and a second edging portion 112 connected to the first edging portion 111. The first edging portion 111 is used to wrap the vehicle window glass 2, and the second edging portion 112 is farther away from the vehicle window glass 2 relative to the first edging portion 111. The decorative layer 12 is disposed on one side of the second edging portion 112, and the second edging portion 112 is provided with at least one groove 1121, which is used to accommodate part of the decorative layer 12.
[0072] The edging component 11 includes a first edging portion 111 and a second edging portion 112. The shape of the first edging portion 111 is adapted to the shape of the window glass 2. Optionally, the first edging portion 111 is bent to connect with the second edging portion 112. A decorative layer 12 is disposed on the surface of the second edging portion 112 and also disposed in a groove 1121. The number of grooves 1121 is one or more.
[0073] Due to the incompatibility between the materials of the edging piece 11 and the decorative layer 12, the connection performance between the edging piece 11 and the decorative layer 12 is poor. In this embodiment, a groove 1121 is provided in the second edging portion 112 of the edging piece 11. During the injection molding process, liquid polyurethane injection molding material can flow into the groove 1121 to fill it. After the liquid polyurethane injection molding material hardens, the portion of the decorative layer 12 located in the groove 1121 provides a fixing mechanical clamping force, thereby firmly fixing the decorative layer 12 to the edging piece 11 and improving the connection performance between the edging piece 11 and the decorative layer 12.
[0074] In one implementation, such as Figure 6 As shown, the depth H1 of the groove 1121 satisfies the following condition: 0.5mm≤H1≤3mm; and / or, the opening width H2 of the groove 1121 satisfies the following condition: 0.5mm≤H2≤3mm.
[0075] For example, the depth H1 of the groove 1121 can be 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.2mm, 2.5mm, 2.8mm, or 3mm, etc. Similarly, the opening width H2 of the groove 1121 can be 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.2mm, 2.5mm, 2.8mm, or 3mm, etc.
[0076] This embodiment limits the depth of the groove 1121 to 0.5mm-3mm and the opening width of the groove 1121 to 0.5mm-3mm. This not only facilitates the flow of polyurethane injection molding material into the groove 1121, but also reduces the overall thickness of the decorative layer 12, thereby improving the aesthetics and product texture of the decorative layer 12.
[0077] Please refer to this as well. Figures 3-8 In one embodiment, the decorative layer 12 includes a first end 121 and a second end 122 disposed opposite to each other. The second end 122 is farther away from the first edge portion 111 than the first end 121. The second edge portion 112 is provided with a first groove 1121a, which is used to accommodate the first end 121.
[0078] The first end 121 is close to the first edge portion 111, and the second end 122 is away from the first edge portion 111. The groove 1121 includes a first groove 1121a, which is located on the portion of the second edge portion 112 close to the first edge portion 111. The first end 121 abuts against the groove wall of the first groove 1121a. The first end 121 is located within the first groove 1121a, which can also be understood as the first end 121 being embedded in the first groove 1121a. Optionally, the first groove 1121a is provided along the extending direction of the second edge portion 112.
[0079] This embodiment improves the connection performance between the edge banding 11 and the decorative layer 12 by placing the first end 121 in the first groove 1121a. In addition, the first groove 1121a can play a role in positioning the decorative layer 12 during the preparation of the decorative layer 12, reducing the difficulty of preparation and realizing the diversification of the decorative layer 12.
[0080] Please refer to this as well. Figures 3-8 In one embodiment, the second edge portion 112 is further provided with a second groove 1121b, which is used to accommodate the second end 122.
[0081] The groove 1121 also includes a second groove 1121b, which is located on the portion of the second edge portion 112 away from the first edge portion 111. A second end 122 abuts against the groove wall of the second groove 1121b. The second end 122 is located within the second groove 1121b, or more precisely, it is embedded in the second groove 1121b. Optionally, the second groove 1121b is provided along the extending direction of the second edge portion 112. Optionally, the first groove 1121a connects to the second groove 1121b, forming an annular groove 1121.
[0082] This embodiment, by placing the second end 122 within the second groove 1121b, ensures that both opposite ends of the decorative layer 12 are within the groove 1121. This not only further improves the connection performance between the edging piece 11 and the decorative layer 12, but also allows the first groove 1121a and the second groove 1121b to cooperate with each other, thus positioning the decorative layer 12 during its fabrication. This further reduces the fabrication difficulty and enables the diversification of the decorative layer 12.
[0083] Please refer to this as well. Figures 4-8 In one embodiment, the second edge-binding portion 112 includes a mounting surface 1122 for connecting the first edge-binding portion 111 and a side surface 1123 bent to connect the mounting surface 1122. The mounting surface 1122 is used to mount the decorative layer 12. The edge-binding component 1 satisfies one of the following conditions: the second groove 1121b is provided on the mounting surface 1122.
[0084] The decorative layer 12 is provided on the mounting surface 1122 and does not cover the side surface 1123. The second groove 1121b is provided on the mounting surface 1122, and the second end 122 covers the mounting surface 1122 and is located in the second groove 1121b.
[0085] Alternatively, the decorative layer 12 may also be provided on the side surface 1123, and the second groove 1121b may also be provided on the side surface 1123.
[0086] The decorative layer 12 is not only provided on the mounting surface 1122, but also covers the side surface 1123. The second groove 1121b is provided on the side surface 1123, and the second end 122 covers the side surface 1123 and is provided within the second groove 1121b. This embodiment further improves the connection performance between the edge banding 11 and the decorative layer 12 by increasing the contact area between the decorative layer 12 and the edge banding 11 and by providing the second groove 1121b on the side surface 1123.
[0087] Optionally, the second edge portion 112 also includes an overlapping surface disposed opposite to the mounting surface 1122. The overlapping surface is bent to connect to the side surface 1123. The overlapping surface is used to overlap the body fitting parts. The second groove 1121b penetrates the side surface 1123 and the overlapping surface.
[0088] Please refer to Figure 9 , Figure 9 A cross-sectional view of the binding material provided in one embodiment of this application. Figure 4 In one embodiment, the width of the groove 1121 gradually decreases along the arrangement direction from the bottom wall of the groove 1121 to the opening of the groove 1121.
[0089] The width of the groove 1121 gradually decreases; in other words, the groove 1121 is trapezoidal in shape, with a wider groove 1121 near the bottom wall and a narrower groove 1121 near the opening. This embodiment, by defining the shape of the groove 1121, makes it difficult for the decorative layer 12 formed by the hardened polyurethane injection molding material to detach from the groove 1121, further improving the mechanical clamping force provided by the portion of the decorative layer 12 within the groove 1121, thereby further improving the connection performance between the edge trim 11 and the decorative layer 12.
[0090] Please refer to Figure 10 , Figure 10 A cross-sectional view of the edge-binding component provided in one embodiment of this application. Figure 4In one embodiment, the second edge-binding portion 112 includes a mounting surface 1122 for connecting the first edge-binding portion 111, and a back surface 1125 opposite to the mounting surface 1122. The mounting surface 1122 is used to mount the decorative layer 12. The second edge-binding portion 112 is provided with a through hole 1126 penetrating the mounting surface 1122 and the back surface 1125. The through hole 1126 is used to accommodate a portion of the decorative layer 12.
[0091] The number of through holes 1126 can be one or more. When there are multiple through holes 1126, they are spaced apart. The through holes 1126 are located between the first groove 11121a and the second groove 1121b. The through holes 1126 penetrate the mounting surface 1122 and the back surface 1125, or they can be understood as penetrating the second edge portion 112 along its thickness direction. The decorative layer 12 is formed in the through holes 1126 by injection molding, filling the through holes 1126.
[0092] In this embodiment, by providing a through hole 1126 in the second edge portion 112, during the injection molding process, liquid polyurethane injection molding material can flow into the through hole 1126 to fill the through hole 1126. After the liquid polyurethane injection molding material hardens, the portion of the decorative layer 12 provided in the through hole 1126 can provide a fixing mechanical claw force. The design of the through hole 1126 in conjunction with the groove 1121 can further improve the connection performance between the edge piece 11 and the decorative layer 12, making the decorative layer 12 more firmly fixed on the edge piece 11.
[0093] Please refer to Figure 10 In one embodiment, the decorative layer 12 further includes a limiting portion 123, which is disposed on the back surface 1125. The limiting portion 123 is disposed corresponding to the through hole 1126, and the width of the limiting portion 123 is greater than the diameter of the through hole 1126.
[0094] The shape of the limiting part 123 can be circular, quadrilateral, trapezoidal, etc., and this embodiment is not limited to this. The limiting part 123 is provided outside the through hole 1126, and since the width of the limiting part 123 is greater than the diameter of the through hole 1126, it limits the position of the decorative layer 12 on the second edge portion 112 and prevents the decorative layer 12 from falling off the second edge portion 112.
[0095] In the injection molding process, the liquid polyurethane injection molding material can flow to the outside of the through hole 1126 to form a limiting part 123. After the liquid polyurethane injection molding material hardens, the limiting part 123 is provided on the back side 1125 of the second edge-wrapping part 112 to prevent the decorative layer 12 from falling off. This can further improve the connection performance between the edge-wrapping part 11 and the decorative layer 12, making the decorative layer 12 more firmly fixed on the edge-wrapping part 11.
[0096] Please refer to Figure 11 , Figure 11 A cross-sectional view of the edge-binding component provided in one embodiment of this application. Figure 5 In one embodiment, the edging assembly 1 further includes an adhesive layer 13 disposed between the decorative layer 12 and the edging member 11, for bonding the decorative layer 12 and the edging member 11.
[0097] Because the materials of the edging piece 11 and the decorative layer 12 are incompatible, the connection performance between them is poor. This embodiment addresses this by adding an adhesive layer 13 between the decorative layer 12 and the edging piece 11. The adhesive layer 13 bonds the decorative layer 12 to the edging piece 11, thus firmly fixing the decorative layer 12 to the edging piece 11 and improving the connection performance between them.
[0098] Please refer to Figure 12 , Figure 12 A cross-sectional view of the edge-binding component provided in one embodiment of this application. Figure 6 In one embodiment, the edging assembly 1 further includes a carrier 14 embedded in the edging member 11, the adhesive layer 13 is disposed on the side of the carrier 14 opposite to the edging member 11, and the decorative layer 12 is disposed on the side of the adhesive layer 13 opposite to the carrier 14.
[0099] The edge-sealing assembly 1 provided in this embodiment also includes a carrier 14 for supporting the adhesive layer 13. The carrier 14 is made of thermosetting rigid plastics such as PC / PA / PP / ABS. These materials are compatible with polyurethane injection molding materials, including polyurethane (PUR) and polyurea (PUA), and have good adhesion. The carrier 14 is embedded in the edge-sealing assembly 11. The carrier 14 and the edge-sealing assembly 11 are an integral structure. The carrier 14 and the edge-sealing assembly 11 are injection molded together. For example, a carrier 14 of a certain shape is placed into an edge-sealing mold and integrally injection molded with the window glass 2 by preparing the edge-sealing assembly 11.
[0100] Furthermore, the support member 14 is an insert that is integrally injection molded with the edge banding member 11. The support member 14 can increase the strength of the edge banding member 11 and reduce the shrinkage marks of the edge banding member 11.
[0101] This embodiment improves the connection performance between the adhesive layer 13 and the edging member 11 by setting a carrier member 14 embedded in the edging member 11 and placing the adhesive layer 13 on the carrier member 14. Furthermore, the adhesive layer 13 bonds and connects the carrier member 14 and the decorative layer 12, further improving the connection performance between the edging member 11 and the decorative layer 12.
[0102] Please refer to Figure 3In one embodiment, the edging member 11 further includes a roughened area 113 for mounting the decorative layer 12, the surface of the roughened area 113 being roughened, and the decorative layer 12 being disposed on the roughened area 113.
[0103] The edging piece 11 provided in this embodiment includes a roughened area 113. The roughened area 113 is used to install the decorative layer 12. The surface of the roughened area 113 has been roughened. The roughening treatment can be performed on the surface of the edging piece using mechanical or chemical methods (mechanical abrasion or chemical corrosion). For example, a smooth layer on the surface of the edging piece 11 can be sanded away to form the roughened area 113.
[0104] This embodiment improves the bonding force and connection performance between the edging piece 11 and the decorative layer 12 by providing a roughened area 113 on the edging piece 11 and a decorative layer 12 on the roughened area 113.
[0105] Optionally, the edging assembly 1 further includes an adhesive layer 13 disposed in the rough area 113, the adhesive layer 13 being used to bond the decorative layer 12 to the edging component 11. This embodiment, by disposing the adhesive layer 13 in the rough area 113 and then using the adhesive layer 13 to bond the edging component 11 to the decorative layer 12, can further improve the connection performance between the edging component 11 and the decorative layer 12.
[0106] Please refer to this as well. Figures 13-16 , Figure 13 A cross-sectional view of the edge-binding component provided in one embodiment of this application. Figure 7 . Figure 14 A cross-sectional view of the edging member and light guide member provided in one embodiment of this application. Figure 1 . Figure 15 A cross-sectional view of the edge-binding component provided in one embodiment of this application. Figure 8 . Figure 16 A cross-sectional view of the binding material provided in one embodiment of this application. Figure 5 .
[0107] In one embodiment, the decorative layer 12 allows light to pass through, and the edging assembly 1 further includes a light guide 15 disposed between the decorative layer 12 and the edging member 11. The light guide 15 includes a light-emitting part and a light guide strip disposed on one side of the light-emitting part. The light emitted by the light-emitting part can be conducted through the light guide strip and emitted through the decorative layer 12.
[0108] The edging assembly 1 provided in this embodiment further includes a light guide 15, which includes a light-emitting part and a light guide strip. The light-emitting part is used to emit light. For example, the light-emitting part is an LED light source. The number of light-emitting parts is at least one. The light guide strip can refract, reflect, and scatter light to conduct light. Optionally, the light guide strip is made of optical-grade transparent acrylic or PC material. The light-emitting part is disposed on the side 1123 of the light guide strip, and / or on the surface of the light guide strip facing the edging assembly 11. The extending direction of the light guide strip is the same as the extending direction of the edging assembly 11.
[0109] The light guide 15 and the edge-sealing part 11 are an integral structure. The light guide 15 and the edge-sealing part 11 are injection molded together. For example, a light guide 15 of a certain shape is placed into an edge-sealing mold, and integrally injection molded with the car window glass 2 by preparing the edge-sealing part 11.
[0110] Specifically, in the preparation process of the edge-binding component 1, the light guide 15 is integrally injection molded with the edge-binding component 11 as an insert, and then injection molding is performed to obtain the decorative layer 12. There is no need to apply an intermediate medium with adhesive properties between the decorative layer 12 and the light guide 15, as it has high adhesive properties on its own. In addition, the above preparation method eliminates the need to set a groove 1121 on the edge-binding component 11 for mechanically engaging the decorative layer 12, which simplifies the structure and improves the preparation efficiency.
[0111] The light guide 15 is obtained through injection molding. Specifically, during the injection molding process, the overall structure and shape of the light guide ensure that light is transmitted internally, and by rationally arranging one or more LED light sources, uniform light distribution is achieved. For example, by controlling the colors of multiple LED light sources, the overall appearance of the product can present a magical color.
[0112] This embodiment further enhances the product's aesthetics by providing a light guide 15 between the decorative layer 12 and the edging component 11. Furthermore, due to the high hardness of the decorative layer 12, the scratch resistance of the edging component 1 is significantly improved, and the decorative layer 12 protects the light guide 15, reducing the likelihood of damage to it.
[0113] Please refer to this as well. Figures 13-16 In one embodiment, the edging member 11 includes a first edging portion 111 and a second edging portion 112 connected to the first edging portion 111. The first edging portion 111 is used to wrap the window glass 2, and the second edging portion 112 is farther away from the window glass 2 than the first edging portion 111. The light guide member 15 is disposed on one side of the second edging portion 112. The second edging portion 112 is provided with at least one groove 1121 and at least one slot 1124. The groove 1121 is used to accommodate part of the decorative layer 12, and the slot 1124 is used to accommodate part of the light guide member 15.
[0114] The light guide 15 includes a third end 151 and a fourth end 152 disposed opposite to each other. The fourth end 152 is farther away from the first edge portion 111 than the third end 151. The second edge portion 112 includes a first slot 1124a and a second slot 1124b. The first slot 1124a is used to accommodate the third end 151, and the second slot 1124b is used to accommodate the fourth end 152.
[0115] In this embodiment, a slot 1124 is formed in the second edge portion 112 of the edge-binding member 11. The portion of the light guide member 15 provided in the slot 1124 can provide a fixing mechanical claw force, so that the light guide member 15 is firmly fixed on the edge-binding member 11, thereby improving the connection performance between the edge-binding member 11 and the light guide member 15.
[0116] Please refer to this as well. Figures 13-16 In one embodiment, the slot 1124 communicates with the groove 1121, the depth of the slot 1124 is greater than the depth of the groove 1121, and the groove 1121 is formed between the light guide 15 and the second edge portion 112.
[0117] The first groove 1121a connects to the first slot 1124a, and the second groove 1121b connects to the second slot 1124b. The depth of the first slot 1124a is greater than the depth of the first groove 1121a, and the depth of the second slot 1124b is greater than the depth of the second groove 1121b.
[0118] This embodiment improves the connection performance between the edge banding 11 and the light guide 15, as well as the connection performance between the light guide 15 and the decorative layer 12, by defining the position and depth of the groove 1121 and the slot 1124. Furthermore, the groove 1121 is formed by surrounding the light guide 15 and the second edge banding portion 112, so that the decorative layer 12 can better cover the light guide 15 and improve the protective effect of the decorative layer 12 on the light guide 15.
[0119] Please refer to this as well.

[0122] S200, the polyurethane injection molding material covers part of the edge banding 11, and a decorative layer 12 is obtained on one side of the edge banding 11 through the injection molding process.
[0123] Then, a thin layer of polyurethane injection molding material is injected onto the outer layer of the edge banding 11 through a mold to form the decorative layer 12.
[0124] Polyurethane injection molding material has low viscosity and high fluidity. It is injected into the cavity of a molding die and cured through a chemical reaction. Because the polyurethane injection molding material is in a liquid state before the chemical reaction, the injection pressure is low and the operation is easy.
[0125] In other words, during injection molding, the polyurethane injection molding material is in a liquid state and can flow onto the surface of the edge banding 11. After a certain period of chemical reaction, it is fixedly bonded to the edge banding 11.
[0126] Through secondary injection molding, the decorative layer 12 is obtained in the edge-wrapping mold by injection molding. The decorative layer 12 can better cooperate with the edge-wrapping part 11, which can not only improve the appearance performance of the vehicle, but also the decorative layer 12 after injection molding has a certain hardness and can act as a skeleton, making the dimensions of the edge-wrapping component 1 more stable.
[0127] S300, the edge-sealing component 1 is obtained, the edge-sealing component 11 is used to wrap the window glass 2, and the decorative layer 12 is used to decorate the vehicle.
