Plating Plating is a process in which an ionic metal is deposited onto a conductive surface to form a non-ionic coating. We perform many different types of electrodeposited plating and cleaning in General and Precious Metals Plating department, most of which are applied to aid in corrosion prevention, cosmetics, and function of different sorts of components. Many materials go through various processes in this department including steel, corrosion resistant steel, and aluminum.
