PP Plating Barrel

Barrel plating is a form of electroplating used for plating a high volume of smaller metal objects in one sitting. It consists of a non-conductive barrel-shaped cage in which the objects are placed before being subjected to the chemical bath in which they become plated.Barrel Zinc plating is the electrolytic deposition of pure zinc metal on conductive base metals, usually steel and cast iron. The zinc plating is applied anywhere from . 0002”-. 001” thick depending on customer requirements.Rack plating differs from barrel plating in that the parts are affixed to metal racks with screws, wires or spring fingers. This causes the parts to remain stationary upon immersion of the metal rack into the plating solution.Rack plating is a method that involves fixture individual parts into an array that is mounted on a solid frame – the so-called plating rack. The plating rack serves the following purposes: To physically hold the parts in a secure manner. To maintain electrical contact with and to pass DC current to the parts.
