Electroplating is a manufacturing process that coats one metal onto the surface of another. It improves the appearance, strength, and functionality of many products across a wide range of industries. By using electricity and a chemical solution, electroplating creates an even, durable layer that enhances both performance and longevity.
Preparing the Surface
Before electroplating begins, the base metal needs to be prepared. Any oils, dirt, or oxides are removed using chemical or mechanical processes to create a clean surface to plate onto. If this step is skipped, the plated layer will not adhere properly. I
How the Electroplating Process Works
Electroplating occurs in a special bath that contains dissolved metal ions. The item being plated acts as the cathode, while a metal anode supplies ions to the bath. When an electrical current is applied, the metal ions bond to the surface of the item. The process must be carefully controlled to achieve the correct thickness and finish.
Materials and Plating Options
Different metals are used depending on the performance requirements of the part. Zinc nickel plating is popular for automotive and engineering components which require high wear resistance. Modifications to bath chemistry and current density can produce coatings that meet specific requirements.

Finishing and Applications
After plating, components may be rinsed and dried or otherwise treated to develop a corrosion resistant surface. Electroplating is a process with broad applications in sectors including electronics, aerospace, and manufacturing.
