The company integrates the R&D, design, manufacturing, sales, and service of electroplating and ultrasonic cleaning equipment. Electroplating is an electrochemical process that involves redox reactions. The basic process entails immersing the part to be plated in a metal salt solution to serve as the cathode, while a metal plate acts as the anode; upon connecting a DC power source, the desired coating is deposited onto the part.
Anodes are classified into soluble and insoluble types. Most are soluble anodes corresponding to the coating material-for instance, zinc anodes for zinc plating, silver anodes for silver plating, and tin-lead alloy anodes for tin-lead alloy plating. However, in certain electroplating processes where anode dissolution is difficult, insoluble anodes are used; for example, platinum or titanium anodes are commonly employed in acidic gold plating, with gold ions in the bath replenished by adding a prepared standard gold solution. For chromium plating, insoluble anodes made of pure lead, lead-tin alloys, or lead-antimony alloys are used.
