Below is a list of Nickel Plating manufacturers from Trenton, New Jersey. Nickel plating is the process of depositing a thin layer of nickel onto another substrate, such as metal or plastic. The two primary purposes for nickel coating are: one, to provide additional material protection from corrosion and wear damage; and two, to endow the substrate being plated with advantageous characteristics of nickel. In addition to having multiple purposes, there are multiple methods by which nickel can be plated. One way is by electroplating and the other way is by electroless plating.
