The electroplating line is an automated equipment that performs surface plating treatment on metal or non-metal components based on the "electrolysis principle". Its core lies in taking the component to be plated as the cathode and the plating metal (or its compound) as the anode, placing them in an electrolyte containing plating metal ions. After applying direct current, the plating metal ions are reduced and deposited on the surface of the cathode, forming a uniform and dense metal coating (common coatings include zinc plating, nickel plating, chrome plating, copper plating, etc.). It fills the gap of hot-dip galvanizing and anodizing in the treatment of "high-precision, lightweight" components.
