A nested ins lamination method for automotive panels

Abstract

The invention relates to a nested INS lamination method for an automobile panel. The automobile panel comprises an automobile panel main body and a decorative plate. The automobile panel main body and the decorative plate have different colors and are provided with a process groove at the junction, or the automobile panel main body and the decorative plate are provided with a process groove. The color of the board is different and there is a height difference. The coating method is as follows: (1) The decorative film is coated on the surface of the substrate of the decorative board by the INS coating process to obtain a decorative board; (2) The decorative film made by INS is used. The panel and the main diaphragm of the car panel are made of the car panel by INS lamination and secondary injection molding process. Specifically, the decorative plate is first placed in the injection mold of the car panel, and then the main body diaphragm of the car panel is placed, and the main body film of the car panel is placed. The sheet intersects and overlaps with the decorative board, and the overlapped portion is 0.1-1.0 mm. The invention not only has various color decoration functions, but also can realize the coating of the process groove or directly reduce the size of the process groove, and can ensure the neat connection of colors.

Description

technical field [0001] The invention belongs to the technical field of lamination of automobile panels, and relates to a method for laminating a nested INS of an automobile panel. Background technique [0002] Traditional technology one: [0003] When the car panel decoration needs to achieve the decorative effect of multiple colors, it can only be disassembled for injection molding, colored by spraying process, and then assembled, which requires a lot of tooling and labor costs. [0004] Two traditional techniques: [0005] When the product adopts the design process tank method and uses INS technology to implement multi-color decoration, the coating of the film cannot completely cover the process tank, and the two-color film in the process tank area will be randomly shifted to the process. At the same time, the common material flowers and welding marks in the injection molding process will affect the appearance and decoration effect of the product; to avoid this problem, ...

Problems solved by technology

[0005] When the product adopts the method of designing process slots and uses INS technology to implement multi-color decoration, the covering of the diaphragm at this time cannot completely cover the process slots, and at the same time, the diaphragms of the two colors will randomly shift to the process The surface of the groove causes the different color of the process groove; at the same time, the common material flowers and weld marks in the injection molding process will affect the appearance and decoration effect of the product; to avoid this problem, secondary processing is required; the manufacturing cost of the product is increased; when the diaphragm is pre-printed When the pattern is embodied in the form of fine positioning, product manufacturing can only produce flat products. When the product is stretched by the difference in different color areas, different areas will be stretched and the junction of the two colors will be deformed. According to the statistics of the existing technology, the stretch The deformation after stretching cannot be in a constant state; it will change according to different external factors, and the consistency cannot be guaranteed
