Nickel-Nickel-Chrome Rack Plating Line

The Nickel-Nickel-Chrome Rack Plating Line is an automated electroplating system that deposits three functional layers onto metal parts: semi-bright nickel , bright nickel, and decorative chrome. This double-nickel structure achieves 48–120 hours of neutral salt spray test (NSS) resistance - 2x longer than traditional copper-nickel-chrome processes.

Our gantry-type rack plating equipment is widely used for automotive exterior parts, bathroom faucets, door handles, and kitchen hardware that require both high corrosion resistance and premium aesthetic appearance. Available in fully automatic or semi-automatic configurations.

Key Specifications

Technical Process

1. Ultrasonic Degreasing – Remove oil and grease from part surfaces

2. Electrolytic Degreasing – Deep cleaning via electrochemical reaction

3. Acid Activation – Remove oxidation film, activate metal surface

4. Semi-Bright Nickel Plating – First nickel layer, leveling and corrosion resistance

5. Bright Nickel Plating – Second nickel layer, brilliant appearance and further protection

6. Decorative Chrome Plating – Top chrome layer for high brightness and wear resistance

7. Rinsing & Drying – Multi-stage rinsing followed by hot air drying
