Below is a list of Copper Plating manufacturers from Dayton, Ohio. Copper plating is the process of depositing a layer of copper onto a solid metal or plastic workpiece. Copper plating is traditionally accomplished through two means: electroplating and electroless plating. Electroplating utilizes an electric current for deposition, whereas electroless plating depends upon a chemical reaction. While copper electroplating is more common than copper electroless plating, electroless plating is still a successful method of copper plating.
