Embodiment 1

[0015] A non-distortion method for wide-faced bright decorative strips. When wrapping glass, inserts are added between the bright decorative strips and the glass, and the inserts are arranged in parallel with the bright decorative strips. The volume of the space between the glasses is reduced, and the amount of PVC material is reduced, thereby reducing the thickness of the PVC edging and reducing the force generated when the PVC edging shrinks. Within the acceptable range of the bright decorative strip, the bright decorative strip is guaranteed. beautiful. The result of production practice shows that the qualified rate of quality is 97%, which is higher than the existing processing technology.

Embodiment 2

[0017] A non-distortion method for wide-face bright decorative strips. When wrapping glass, apply a primer to the edge of the bottom surface of the bright decorative strips to reduce the area of ​​the primer, that is, to reduce the shrinkage transmission force value of PVC wrapping Medium, so that the shrinkage force is within the bearing range of the bright trim, ensuring the beauty of the bright trim. The result of production practice shows that the qualified rate of quality is 95%, which is higher than the existing processing technology.

Embodiment 3

[0019] A non-distortion-free method for wide-surface bright decorative strips. When wrapping glass, paste high-temperature-resistant tape on the bright decorative strips. The high-temperature-resistant tape is a double-sided tape with certain elasticity. When the PVC material shrinks, The PVC material is in contact with the bright decorative strip through the high temperature resistant tape. Paste the high temperature resistant tape to isolate the bright trim from the binding, and isolate the force generated by the shrinkage of the binding from the bright trim. The result of production practice shows that the qualified rate of quality is 98%, which is higher than the existing processing technology.

Abstract

The invention relates to a method for ensuring a wide bright decorative strip to be free of distortion. The method is characterized in that the wide bright decorative strip is ensured to be free of distortion by adopting one or more of methods of reducing PVC material dosage, reducing a connecting area between PVC and the bright decorative strip or transferring PVC material shrinking force between the bright decorative strip and glass during edge covering of glass. Compared with the prior art, the method has the advantages of reducing PVC edge-covering shrinking force in aspects of a force acting object, a force transmission medium, a force generating object and the like, so that the shrinking force is within a bearing range of the bright decorative strip, and the aesthetic measure of the bright decorative strip is ensured.

Description

technical field [0001] The invention relates to the production field of automobile corner window glass, in particular to a distortion-free method for wide-surface bright decorative strips. Background technique [0002] Most of the popular automobile corner window glass in the market is a narrow surface bright trim strip made of stainless steel. The requirements of the assembly surface cannot be met. Therefore, in order to meet the needs of consumer groups, large and wide-surface bright decorative strips are applied to products, and are molded by integral injection molding in the mold, which is convenient and simple and can meet market demand. [0003] During in-mold injection molding, the molten PVC material enters between the bright trim strip and the glass to wrap the glass, while adhering to the glass, while bonding with the glue coated on the bottom of the bright trim strip, so that the bright trim strip and the glass are bonded together. The glass is connected. Since...
