Vehicle decoration part, vehicle window glass assembly and manufacturing process and molding device thereof

A process for manufacturing a vehicle window glass assembly, the vehicle window glass assembly comprising a glass body and an encapsulation covering periphery of the glass body, wherein the vehicle window glass assembly further comprises a vehicle decoration part, the vehicle decoration part comprising a decoration body and a decoration film attached to one or more surfaces of the decoration body, a material of the decoration body being metal, and a material of the decoration film being flexible material and forming a decoration surface, and the process for manufacturing comprising:

• a. placing the vehicle decoration part into a cavity of a mold and enabling surface of the vehicle decoration part to be adhered to inner wall of the cavity;
• b. placing the glass body which is cut and shaped into the cavity and fixing the glass body in place;
• c. injecting thermoplastic polymer into the cavity to form the encapsulation, and enabling the vehicle decoration part to be integrally molded with the encapsulation on at least one peripheral edge of the glass body,
• wherein the process further comprises cooling the cavity in said injecting thermoplastic polymer into the cavity to form the encapsulation, and enabling the vehicle decoration part to be integrally molded with the encapsulation on at least one peripheral edge of the glass body, and the cooling is performed by providing a cooling member on the inner wall of the cavity that is adhered to the vehicle decoration part.
