Strict control of the barrel steel nickel plating process to reduce production costs and improve product quality. After studying the processing technology, the company compared the one-step method, the two-step method and the three-step method of the barrel steel nickel plating, and found that the two-step method is very easy to control and manage in the process. It mainly introduces the control of the pre-treatment process of the nickel plating of the battery steel shell, the control of the electroplating process (including the temperature, time, current, pH of the plating solution, the pH of the recovery tank and the control of the water supply mode) and the control of the post-treatment process (including bleaching, medium and middle). And, rust prevention, dehydration and drying), in which the post-plating treatment process control is the most important. Therefore, our company will strictly follow the two-step process rules for the production of battery steel shells.
