500T Natural Gas Anodizing Production Line with 8500MM Max Length and 350m²/T Coverage Area

Professional 500T capacity anodizing production line for aluminum profiles, featuring energy-saving technology and full customization options.

The 500T Aluminum Profile Anodizing Production Line is a large-scale automated industrial system designed for surface treatment of aluminum profiles, with an annual capacity of 500 tons. This system creates a dense oxide layer through electrochemical anodizing, significantly enhancing corrosion resistance, wear resistance, aesthetics, and paint adhesion. Ideal for construction (curtain walls, windows), automotive parts, electronics housings, and decorative applications.

• Pre-treatment
  • Degreasing: Removes oils and contaminants
  • Alkaline Etching: Eliminates natural oxides and minor scratches
  • Neutralization: Activates the surface via acid wash
• Anodizing
  • Electrolysis Tank (sulfuric acid-based): Generates a porous alumina layer (5-25 μm thickness adjustable)
• Coloring (Optional)
  • Electrolytic Coloring: Tin/nickel salts produce bronze, champagne, etc
  • Dyeing: Organic dyes for multicolor effects
• Sealing
  • Hot/Cold Sealing: Closes micropores to improve durability

• Tank System: PP/PVC corrosion-resistant tanks (degreasing, anodizing, coloring)
• Power Supply: High-frequency rectifiers (constant voltage/current, ≥30% energy-saving)
• Hoist System: Automated crane (PLC-controlled, precision positioning)
• Temperature Control: Titanium heat exchangers/chillers (±1°C accuracy)
• Emission Control: Acid scrubbers (fume treatment), wastewater recycling (compliant with ISO 14001)

• High Efficiency: Auto-transfer, adjustable cycle time (3-15 mins/rack)
• Energy Saving: Rectifiers with ≥95% conversion efficiency (IP54 rated)
