Electroless Plating (Chemical Plating)
What Is Electroless Plating?
Electroless plating is a metal deposition process that does not require external electric current. Instead, a chemical reduction reaction allows metal ions to deposit uniformly onto the component surface.
This technology is particularly suitable for custom metal parts requiring:
High wear resistance
Excellent corrosion resistance
Electrical conductivity
Dimensional stability and precision
By forming a uniform coating layer, electroless plating significantly improves the durability, reliability, and service life of components in demanding working environments.
