The copper plate is equipped with a stainless steel conductive hook, and the copper plate is hoisted in the plating tank for electroplating. Its main advantage is that the electroplating equipment is simple. The main body of the equipment is a DC power supply and a plating tank. The production line investment is low and easy to build, so this electroplating method is widely used. However, the disadvantage is that the plating solution corrodes the white steel hanger, and the impurities of the white steel hanger are integrated into the plating solution. The amount of impurities formed in the plating solution increases, which reduces the conductivity efficiency and thus reduces the utilization rate of the main material; this electroplating method belongs to semi-open electroplating, the chromium mist volatilization is large, and the copper plate after electroplating brings out a large amount of chromium anhydride, which has a greater impact on the environment; the non-electroplated surface of the copper plate needs to be sealed with insulating tape.
