A certain number of small parts are loaded into the barrel from the opening during electroplating, and then the opening is closed by covering the barrel door. The barrel wall plate is covered with a large number of small holes. The conduction of current between the parts and the anode, the update of solution inside and outside the barrel, and the exhaust of waste gas during electroplating all need to pass through these small holes.
