Zinc Plating of a Steel Transfer Case Mount for the Off-Road Automotive Industry

A customer in the off-road automotive industry commissioned us to treat a steel aftermarket automotive part with our type II zinc plating process. Our rack process was employed; first the unit was cleaned and prepped, then immersed into the chemical bath and the proper current was applied. After the zinc was deposited, the part underwent post treatment of gold chromate to reach the specified finish. We were able to achieve the clean, smooth, and corrosion resistant surface that the customer requested. This process was plated holding to the requirements set for ASTM 633B Type II electroplating. While we have zinc plating capabilities up to 13′ x 2′ x 4′, the finished dimensions for this part shown here is 2-½’ x 1′.

Dimensional and visual inspections were carried out throughout processing to ensure quality. This plating is applied with tolerances of .0003″ – .0005″ throughout treatment. The finished part was delivered to the client in Paso Robles, California as required. Typical turnaround time for a project of this nature is 2 – 3 days. We hold our processes and work to the highest standards, offering all types and classes of zinc plating. For more information about this project, please see the table below or contact us directly.
