Chrome plating equipment for sale: (Agent wanted)
Note: The electroplating technical processes may be different from customers to customers based on different different surface requirements and environmental conditions, please select the most suitable solution based your requirement.
1, Iron chrome plating equipment process:
Wax removal→Hot dip degreasing →Cathode→Electrolytic degreasing→Weak acid etching→Pre-plating alkaline copper→Acidic bright copper (Select) →Brightness nickel plating→Chrome electro plating or other;
Wax removal→Hot dip degreasing →Cathode→Electrolytic degreasing→Weak acid etching→Semi-bright nickel plating→High sulfur nickel electroplating→Brightness nickel plating→Nickel sealing→Chrome electro plating or other;
2, Zinc alloy chrome plating process:
Wax removal→Hot-dip degreasing→Cathode electrolysis degreasing →Pickling → → Bright copper pyrophosphate (optional) → Bright Acid Copper (optional)→Bright nickel plating→chrome electroplating;
3, Stainless steel direct chromium plating process:
1) Electrochemical degreasing→Hot water rinse→Cold water rinse→Immersion acid activation (1ml/L HCL, 10ml/L H2SO4, room temperature,half a minute; suitable for automatic on-line stainless steel chrome plating, not suitable for copper or nickel)→Water washing→Chrome electro plating.
2) Cathode electrochemical degreasing→Washing→Activation (10A/dm2)→Direct chrome plating.
3) Chemical degreasing→Washing→Anode electrochemical degreasing (0.5A/dm2)→Washing→Pickling activation (1ml/L HCL, 10ml/L H2SO4, room temperature, 45S)→Washing → Chrome plating.
Note: When chrome plating, should use of 1.5 to 2 times of normal plating current density to plate 3 to 5 minutes, then plating as normal current density, to minimize the residence time of the transition between the various processes caused.
