Coating on Plastics
More and more plastic products are used in fields where metal was previously predominant. In these cases, the end product should meet functional requirements (durability and scratch resistance) and aesthetic appearance. There are basically three ways to achieve this result; electroplating, painting and PVD coating. Electroplating has a typical surface hardness of around 600 HV. The typical thickness of around 30 µm levels the surface imperfections. Electroplating, however, is a wet, environmentally-unfriendly process and a source of hexavalent Cr6+, which is considered carcinogenic and therefore banned in more and more countries. Furthermore, chromium plating is mainly limited to ABS. The main disadvantage of painting is the absence of an attractive metal look.
