Problems solved by technology

[0005] However, when the injection molding process of the prior art forms glass edging, the solution shrinks in the mold cavity due to cooling, and sink marks appear on the surface of the glass edging, which makes the size of the glass edging formed by injection molding smaller than the design specification, thereby The glass edging cannot be well matched with other parts of the car window, and the sink marks formed on the surface of the glass edging also affect the appearance of the car

Embodiment Construction

[0022] The automobile edging formed by injection molding process is prone to sink marks, which affects the appearance of the car and makes the size of the glass edging formed by injection molding smaller than the design specification, so that the glass edging and other parts of the car window cannot be well connected. match.

[0023] After in-depth analysis of the existing injection molding process and mechanism, it was found that the reason for the sink marks on the surface of the automobile hemming is that some automobile hemming products have a large injection thickness, and when the injection molding solution is cooled in the mold cavity, the surface of the solution The temperature is low and the cooling is fast, while the temperature inside the solution is high and the cooling is slow. In this case, when the injection molding solution is cooled and molded on the outside, the inside is not yet molded; when the injection molding solution inside is cooled and molded, the volu...

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 (100, 200) and an elastic body (110, 210); adhering the elastic body (110, 210) to a surface of the vehicle window substrate (100, 200), wherein the surface is close to a lateral side of the vehicle window substrate (100, 200); and implementing an injection molding process for forming an encapsulation (120, 220), wherein the injection molding process is performed at an injection molding temperature lower than a melting temperature of the elastic body (110, 210). The method for manufacturing a vehicle window component and the vehicle window component may have no shrink mark.

Description

technical field [0001] The invention relates to the technical field of glass edge wrapping, in particular to a method for manufacturing a vehicle window assembly and the vehicle window assembly. Background technique [0002] With the rapid development of automobile technology, the encapsulation products of automobile glass are becoming more and more diverse and complex. The periphery of the automobile glass is generally formed by injection molding process to increase the airtightness, noise reduction and safety of the automobile glass. [0003] The Chinese patent application whose publication number is CN102180081A discloses an automobile rear quarter window assembly. refer to figure 1 , shows a schematic diagram of the automobile rear quarter window assembly in the said Chinese patent application. The automobile rear quarter window assembly includes: a glass 11 and a glass encapsulation 12 formed around the glass 11 . The glass edge 12 includes a glue-applied surface 12...
