An even electroplating film can be formed on the surface of those products in complex shape by means of electroless chemical nickel plating. The method is thus widely used in surface processing of various products which have high requirements in anti-corrosiveness, hardness and precision. Phosphor is co-separated by means of electroless chemical nickel plating and its separated hardness reaches HV550. An automatic control system is adopted for plating solution so as to guarantee the steady physical performance of electroplating film, such as thickness, hardness, etc. With a complete set of production line, reliable production and management system and advanced inspection instrument, staff members and workers earnest in work are strict in quality inspection.
