Our Nickel-Chrome Barrel Plating Line is specifically designed for decorative and corrosion-resistant finishing of small metal parts in bulk quantities. The double nickel layer (semi-bright + bright nickel) combined with decorative chrome provides exceptional corrosion protection and a brilliant, mirror-like finish.

This barrel nickel-chrome plating system utilizes a high-rail or low-rail gantry configuration with specialized barrels for small parts processing. The automated line ensures consistent quality across every batch, making it ideal for high-volume decorative plating applications.

Key Specifications

Key Advantages

Intelligent Fuzzy-Control Plating Management System

Flexible Process Programming

Users can create new plating processes simply by entering process parameters without requiring PLC reprogramming.

Multi-Product Mixed Production

Different products with different process routes can run simultaneously on the same plating line.

Automatic Rework Function

When coating thickness inspection shows NG results, workpieces can automatically return to the designated plating tank for additional plating.

Dynamic Process Adjustment

Operators can modify:

immersion time

dripping time

transfer time

process sequence

without requiring supplier intervention.
