The metal plating process is a manufacturing process in which a thin layer of metal coats a substrate. It involves creating the outer coating with copper, nickel, chromium, or any other metal that has corrosion resistance and improves its appearance.
It is usually done by immersing metal in an acid solution with an anode electric current and cathode.

▶ There are three major metal plating techniques used in different industries they are:
1. Electroplating or electrolytic plating: It is a metal plating process, that involves electric currents in an electrolyte solution to dissolve charged metal particles.
2. Autocatalytic or electroless plating: This is a method of plating, without the need for an external power source.
3. Immersion plating: The immersion plating process involves immersing a metal into a chemical compound that contains metal ions of a noble metal.
▶ There are different types of metal plating methods to employ when plating a substrate. These include:
○ barrel plating
○ rack plating
○ manual plating
○ automated plating.
▶ Factors to consider for metal plating surfaces include:
○ metal surface finish
○ pre-plate material condition
○ thickness tolerance
○ thread inclusion.
Different chemicals and coating are used in the metal plating process to improve the results and increase the stability.
