Division overview:
At present, there are 2 rack plating lines. Main processed product category: Auto parts, accessories for medical devices, precision sheet metal parts, hardware stamping parts, built-in auto parts, computer accessories, accessories for household appliances & elevators, etc. (Enjoy the leading technical level and good reputation in the industry.)
Main plating type:
Trivalent chromium blue-white zinc plating; 2. Trivalent chromium color zinc; 3. Trivalent chromium white zinc; 4. Hexavalent chromium color zinc, etc.
Equipment parameter:
Tank body specification: 3.5m, 0.7m wide, 1.4m high
Processing capacity: 2,000,000 dm²/month
Processing material: Iron-based material
Production process advantages:
In the electrolyte, there is no cyanide, and metallic ion concentration is low, which helps to prevent public hazards.
After the adjustment of pH value, Zn2+ in the electrolyte is easy to form Zn（OH）2 sediment,Convenient for recycling and reuse.
The electrolyte composition is simple, easy to carry out management.
There is excellent metal distribution (1A 30-minute Hull specimen is taken as an example, and there is only 25% change).
The zinc layer has good brightness, easy to carry out passivation, with excellent malleability, high burning point and no bubble, suitable for high-current density areas.
