In the automotive industry, plating on plastics is mainly used in interior and exterior trims, as well as electronic components. Plating on plastics not only enhances the fashionable appearance of cars but also gives the overall vehicle a sense of high-end quality. Furthermore, Plating on plastics is not only easy to mold and control in size, allowing for the creation of relatively complex and diverse shaped parts, but its surface can also exhibit various high-grade metallic textures.
The purpose of pre-treatment for coating is to improve the adhesion between the coating and the plastic surface, and to form a conductive metal base layer on the plastic surface. The formation of the conductive layer requires several steps such as degreasing, roughening, activation, and peptization.

Plating on plastic technology is a surface finishing plating process based on plastic substates. Plating on plastic products can not only show a metallic texture, but also reduce the weight of the finished product. It can effectively improve the appearance and decoration of finished plastics while improving their electrical, thermal, and corrosion resistance properties.
