Abstract

A method for manufacturing a vehicle window component and a vehicle window component, wherein the method for manufacturing the vehicle window comprises: providing a vehicle window substrate and an elastic body; adhering the elastic body to a surface of the vehicle window substrate, wherein the surface is close to a lateral side of the vehicle window substrate; and implementing an injection molding process for forming an encapsulation, wherein the injection molding process is performed at an injection molding temperature lower than a melting temperature of the elastic body. The method for manufacturing a vehicle window component and the vehicle window component provided by the present disclosure may have no shrink mark.

First claim

What is claimed is:

1. A method for manufacturing a vehicle window component, comprising:
providing a vehicle window substrate and an elastic body;
adhering the elastic body to a surface of the vehicle window substrate, wherein the surface is close to a lateral side of the vehicle window substrate; and
implementing an injection molding process for forming an encapsulation, wherein the injection molding process is performed at an injecting molding temperature lower than a melting temperature of the elastic body, wherein the formed encapsulation is located on the lateral side, wherein the encapsulation embraces the elastic body, and wherein a linear distance between the elastic body and an outer edge of the vehicle window substrate is larger than or equal to 4 mm.

2. The method according to claim 1 , wherein the elastic body is porous.

3. The method according to claim 1 , wherein the elastic body comprises triphenyl phosphate, vulcanized rubber, ethylene-propylene-diene monomer rubber or polyurethane.

4. The method according to claim 1 , wherein a ratio of a thickness of the elastic body to a thickness of the encapsulation is less than or equal to 20%.

5. The method according to claim 1 , wherein implementing the injection molding process for forming the encapsulation comprises:
implementing the injection molding process for forming a rigid plastic layer; and
implementing the injection molding process for forming a flexible plastic layer on at least a portion of the rigid plastic layer.

6. The method according to claim 1 , wherein the elastic body is adhered to the surface of the vehicle window substrate by an acrylic pressure sensitive adhesive or a silicone pressure sensitive adhesive.

7. The method according to claim 1 , wherein the vehicle window substrate comprises organic glass, polyvinyl chloride or inorganic glass.

8. A vehicle window component comprising:
a vehicle window substrate;
an elastic body adhered to a surface of the vehicle window substrate, wherein the surface is close to a lateral side of the vehicle window substrate; and
an encapsulation located on the lateral side, wherein the encapsulation embraces the elastic body, and wherein a linear distance between the elastic body and an outer edge of the vehicle window substrate is larger than or equal to 4 mm.

9. The vehicle window component according to claim 8 , wherein the elastic body is porous.

10. The vehicle window component according to claim 8 , wherein the elastic body comprises triphenyl phosphate, vulcanized rubber, ethylene-propylene-diene monomer rubber or polyurethane.

11. The vehicle window component according to claim 8 , wherein a ratio of a thickness of the elastic body to a thickness of the encapsulation is less than or equal to 20%.

12. The vehicle window component according to claim 8 , wherein the encapsulation comprises:
a rigid plastic layer embracing the elastic body; and
a flexible plastic layer overlaying at least a portion of the rigid plastic layer.

13. The vehicle window component according to claim 8 , wherein the elastic body is adhered to the surface of the vehicle window substrate by an acrylic pressure sensitive adhesive or a silicone pressure sensitive adhesive.

14. The vehicle window component according to claim 8 , wherein the vehicle window substrate comprises organic glass, polyvinyl chloride or inorganic glass.
