Core Structure:

The chrome plating production line is composed of five main systems:
Pre-treatment System – A critical stage that ensures a clean, smooth surface for firm chromium adhesion. It includes:
Degreasing to remove oils and contaminants,Pickling to eliminate oxides and rust, and Activation to improve surface adsorption and plating uniformity.
Electrolytic System – The core section of the line, comprising:
Highly corrosion-resistant plating tanks, typically made of steel lined with lead or PVC, filled with a chromic acid-based electrolyte,Insoluble lead-tin alloy anodes to prevent anode dissolution and electrolyte contamination, and An adjustable DC power supply providing 10–15V high voltage to meet the high current density requirements of chrome plating.
Post-treatment System – Ensures coating quality and corrosion resistance through:
Multiple rinsing stages to remove residual chromic acid and prevent corrosion,Optional passivation for enhanced protection, and Low-temperature drying to prevent oxidation.
Conveying System – Uses automated racks to ensure smooth and stable transfer of workpieces between each process stage.
Control System – Powered by PLC and touchscreen interfaces, it provides real-time monitoring of electrolyte temperature (40–55°C), chromic acid concentration, and coating thickness (precision ±2 μm), ensuring consistent and reliable production.

Key Advantages:
The chromium layer features high hardness (HV800–1200) and excellent wear resistance, significantly extending the service life of components. Its smooth, mirror-like surface offers both decorative appeal and friction reduction. Adaptable to a wide range of metallic substrates, the chrome plating line is an essential system for enhancing surface performance in modern manufacturing industries.
