Companion focuses on providing complete and efficient cleaning and surface treatment services for advanced process kits.

We provide surface treatment services for metallic materials such as copper, stainless steel, iron, aluminum, zinc alloy, magnesium alloy, and titanium alloy, as well as non-metallic substrates including engineering plastics. Our processes encompass precious metal plating (gold, silver), conventional electroplating (copper, nickel, tin), specialized techniques (electroless nickel plating, tin-zinc alloy plating), and substrate pre-treatment methods (electropolishing for stainless steel and aluminum alloys, etching reinforcement, among others).




We provide professional surface engineering solutions for clients in electronics, medical, construction, automotive, power, energy, and high-end equipment manufacturing.
