Our Custom Zinc-Nickel Plating Process 

• Part-specific racking and tooling
  We design racking systems to ensure even plating on all surfaces, especially important for fragile features and recessed areas. 

• Parameter tuning and chemistry control
  We adjust current density, bath chemistry, and agitation to achieve accurate coating thickness and alloy consistency, supporting high-performance zinc-nickel electroplating. 

• Post-treatment with clear passivates
  Only clear trivalent passivates are used to meet visual and corrosion requirements without compromising torque values or mating surfaces. 

• Integrated quality control
  Every batch is verified with salt spray testing, in-line inspection, and coating validation to ensure durability and corrosion resistance in real-world use.
