Electroplating is a technology that uses electrolysis to attach a layer of metal film on the surface of metal, so as to prevent corrosion, improve wear resistance, conductivity, reflectance and enhance aesthetics. Electroplating technology is widely used in many zinc alloy and aluminum alloy die castings.
Process flow: pretreatment → cyanide free alkaline copper → cyanide free Cupronickel tin → chromium plating
1. High gloss coating, high quality metal appearance.
2. The substrate is SUS, Al, Zn, Mg, etc.,the cost is lower than PVD vacuum plating.
The environmental protection is poor and the risk of environmental pollution is high.
