Zinc-Nickel Alloy Rack Plating Line

A Zinc-Nickel Alloy Rack Plating Line is an advanced electroplating production system used to deposit a zinc-nickel alloy coating onto metal components. Compared with traditional zinc plating, zinc-nickel coatings provide significantly higher corrosion resistance, improved thermal stability, and better protection for high-strength steel parts.

JUNDA designs and manufactures fully automated zinc-nickel plating systems that integrate process control, chemical dosing, rinsing systems, passivation treatment, and environmental protection equipment into a complete turnkey solution.

Why Choose Zinc-Nickel Alloy Plating?

Zinc-nickel electroplating has become one of the preferred surface treatment technologies in the automotive and industrial sectors because of its exceptional corrosion resistance and durability.

Key Benefits

Salt spray resistance up to 500–1,000 hours

Superior corrosion protection compared with standard zinc coatings

Excellent coverage on complex-shaped components

Low hydrogen embrittlement risk for high-strength steel

High-temperature resistance up to 220°C

Environmentally friendly trivalent chromium passivation options

Long service life in harsh operating environments
