Compared with metals, plastics have advantages of low price, light weight and flexible shaping, etc. On the way to seeking energy conservation and environment protection and being luxury and gorgeous, plastics plating process has played an important role in decorative protection process of automobiles. Plastics plating process is widely used in auto parts plating no matter inside or outside the car, such as the logo, door handle, bumper, wheel house, etc.
The process flow of plastics plating:
The process plow
