Vehicle lamp plastic part machining process with reflecting surface and vehicle lamp plastic part

Abstract

The invention belongs to the technical field of vehicle lamp manufacturing, and discloses a vehicle lamp plastic part machining process with a reflecting surface and a vehicle lamp plastic part. The machining process comprises the following steps that firstly, a first injection transparent plastic part is taken as a reflecting surface carrier; based on the light transmission characteristic of thetransparent plastic part, the reflecting surface carrier is taken as a substrate of the coating, an aluminum film is plated on the back surface of the reflecting surface carrier, the surface, facing the reflecting surface carrier, of the aluminum film is a front surface, and the front surface of the aluminum film is a light reflecting surface; and the reflecting surface carrier coated with the aluminum film on the back side is used as a base body, and other structures are injected on the back surface for two times or multiple times to form the target coated vehicle lamp plastic part. Accordingto the vehicle lamp plastic part machining process, the corrosion resistance and the anti-aging performance of the coating layer of the vehicle lamp plastic part can be further improved, defects suchas collision or pollution are not likely to be caused in the vehicle lamp assembly process, the effect of protecting the metal film is effectively achieved, the corrosion resistance of the aluminum film is enhanced, the procedure is reduced, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of car lamp manufacturing, and relates to a plastic fitting for a car lamp, in particular to a car lamp plastic part with mirror reflection, especially to a car lamp plastic part with a reflective surface and its processing technology. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of automobile technology, the performance of vehicles has been more and more able to meet people's needs, but with the improvement of aesthetic level, people are paying more and more attention to the appearance of cars. Car lights are an indispensable and important part of a car. On the one hand, the requirements for car lights lie in their lighting effects, and on the other hand, their impact on the appearance of cars. Car lights are the soul of car appearance. Appearance has a weight-lifting effect. [0003] Reflective surfaces are essential in car lights, not only used ...
