650 Ton/month Automatic Aluminum Anodizing Line with 8-12µm Film Thickness and 6500mm Max Profile Length

The 650 Ton/month high quality automatic aluminum anodizing line is a comprehensive metal surface treatment system designed for industrial-scale production. This advanced process enhances aluminum profiles by forming a protective oxide layer that significantly improves corrosion resistance, hardness, and wear resistance while providing an aesthetically pleasing finish.

Anodizing involves electrochemically treating aluminum surfaces in acidic electrolyte solutions to create dense, durable oxide films that protect the metal from environmental damage and extend product lifespan.

• Degreasing [Free sulfuric acid 180±30 g/l] - 1 Tank
• Alkaline Etching [Free alkali 40-60g/l, Al³⁺ 30-120g/l] - 2 Tanks
• Neutralization [Free sulfuric acid 180±20g/l] - 1 Tank
• Anodising [Free sulfuric acid 140-180g/l, Al³⁺≤20g/l] - 3 Tanks
• Colouring [Stannous sulfate 3-8g/l, Free sulfuric acid 15-25g/l, PH 0.8-1.2] - 2 Tanks
• Medium Temperature Sealing [PH 5-6.5, Nickel ion 0.8-1.3g/l, Fluorion 0.3-0.7 g/l] - 1 Tank

Anodizing Treatment Area:

• Each anodizing process requires 40 minutes
• Total jigs per year: (2 racks × 3 tanks × 60min/h) ÷ 40min × 600 hours = 5,400 jigs
• Design capacity: 50m² per jig (100m² per tank)
• Annual treatment area: 5,400 jigs × 50m²/jig = 270,000m²

Production Output:

Monthly output: 270,000m² ÷ 350m²/T × 0.9 = 694T ≥ 650T

Power Consumption:

• Anodizing Tank: 100m²/tank × 130A/m² ÷ 0.9 = 14,444A/tank
• Power Rectifier: 15,000A = 3 units
• Coloring Tank: 100m²/tank × 70A/m² ÷ 0.9 = 7,777A/tank
• Color Rectifier: 8,000A = 2 units
