Optimizing Decorative Nickel-Chrome & Faucet Electroplating via Controlled Pulsed Current Modulations
Industrial solutions for enhancing throwing power in complex recesses of sanitary hardware and automotive trims.
In manufacturing sanitary faucets, door handles, and automotive decorative trims, achieving brilliant mirror-finish nickel and chrome coatings without shadowing is the primary brand quality benchmark.
Complex Geometrical Recess Challenges:
Sanitary hardware features internal threads and deep recesses. In traditional DC plating, current concentrates at outer edges (burning/dulling nickel) while failing to deposit inside deep recesses.
Loni Pulsed Power Solution:
High-frequency current pulses equalize current density distribution across all surface contours (enhancing throwing power).
Operational Advantages in Production Lines:
- Achieves uniform nickel thickness (12 to 15µm) inside deep valve cavities.
- Activates leveling and brightener additives in Watts Nickel Baths for mirror reflectivity.
- Passes rigorous 24-hour Copper-Accelerated Acetic Acid Salt Spray (CASS) tests per ASTM B368.
