Analysis management using a capillary electrophoresis analyzer! Each component was individually supplied and managed.
There were issues with the black nickel plating process, such as peeling of the coating and differences in color between batches, resulting in poor yield. Black nickel plating is an alloy plating of nickel and zinc, and its blackness and adhesion of the coating are influenced by the concentration of the components. At Sun Industry, we analyze and manage not only the concentrations of nickel and zinc but also organic additives using a specialized analysis device called a capillary electrophoresis analyzer. By individually managing the replenishment of each component, we maintain a consistent liquid concentration, ensuring that the black color and adhesion quality are preserved. [Issues] ■ Differences in color between batches ■ Peeling of the plating ● For more details, please visit our company website and contact us.
