Specialized equipment for forming metal films on the surface of metal parts and electronic components through electrochemical reactions. Includes electrolytic plating equipment, electroless plating equipment, barrel plating equipment, and rack plating equipment. Used for metal surface treatment of automotive parts, electronic devices, and precision machinery components to improve corrosion resistance, provide conductivity, and enhance decorative properties. Covers a wide range from integrated systems including plating solution circulation systems, power supply units, and pre/post-treatment facilities to individual plating tanks. Distinguished from simple coating equipment or physical surface treatment devices, this equipment group specializes in metal film formation through electrochemical reactions.
