Zinc or Nickel Plating Production Line

Metal electroplating line is widely used in aircraft and auto parts, machinery parts, metal, hardware processing industries, including cooper plating, silver plating, zinc plating, nickel plating, gold plating, chrom plating, anodizing, electrophoresis production line,etc.

Zinc-nickel alloy is an anti-corrosion coating with excellent corrosion resistance. At the same time, it has good mechanical properties and does not change the mechanical properties of the steel after plating. It has excellent brazing properties and is easy to weld under various conditions. The internal stress of the coating is small, which is comparable to that of the cadmium coating in the torsion-tension test. The plating solution has good dispersing ability and covering ability, high current efficiency, bright and smooth coating.
The zinc-nickel alloy plating bath has weak acid chloride type, sulfate type and alkaline zinc acid type.

The surface condition and processing requirements during electroplating, select the appropriate steps, and perform the necessary finishing processing on the surface of the part, so that the part has a smooth and clean surface, which is an important link in obtaining a high-quality coating.
