Automatic Anodizing Line | Aluminum Anodizing Equipment | Automated Surface Treatment Solution
1. Product Overview
The Automatic Anodizing Line is an integrated system combining automated conveying, process treatment, and intelligent control. It is designed to produce a uniform and dense oxide layer on aluminum surfaces.
This oxide coating enhances:
Corrosion resistance
Wear resistance
Surface aesthetics
It is widely used in precision manufacturing and industrial applications.

2. Working Principle
The system operates based on electrochemical oxidation:
Aluminum workpiece acts as the anode
Inert materials such as lead plates serve as the cathode
The system operates in sulfuric acid or oxalic acid electrolytes
When DC power is applied:
The anode forms an aluminum oxide (Al₂O₃) layer
The cathode releases hydrogen gas
By controlling:
Current density
Processing time
The coating thickness can be adjusted:
Standard: 5–20 μm
Customizable as required
