Copper-Nickel-Chrome Barrel Plating Line

Our Copper-Nickel-Chrome Barrel Plating Line provides a complete decorative finishing solution for small metal parts requiring superior adhesion and corrosion protection. The copper strike layer ensures excellent bonding to zinc die castings and steel substrates, followed by bright nickel for brilliance and decorative chrome for the final finish.

This CNC barrel plating equipment is ideal for faucet components, door handles, lock parts, and decorative hardware. The automated barrel line ensures consistent quality across high-volume production runs.

Technical Parameters

Intelligent Process Control

Conventional plating lines usually operate according to fixed programs. When process routes, treatment times, or product types change, suppliers often need to modify the control program.

JUNDA's control system allows operators to manage process data directly through the operating interface.

Functions include:

Process recipe creation

Treatment time adjustment

Dripping time adjustment

Multi-product production scheduling

Process route modification

Automatic return to specified tanks for additional processing when required

This operating method reduces production interruptions caused by process changes and product switching.
