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. Through electrochemical anodizing, it forms a dense oxide layer on aluminum surfaces, enhancing corrosion resistance, wear resistance, aesthetics, and paint adhesion. It is widely used in construction (curtain walls, windows), automotive parts, electronics housings, and decorative applications.

The line includes the following key stages (customizable per requirements):

• 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)
• Consistency: PLC+HMI interface for digital parameter control
• Eco-Friendly: Closed-loop water system, ≥80% acid recovery
• Modular Design: Expandable for electrophoresis/powder coating

• Materials: 6063, 6061, 7075 alloys (profiles/sheets)
• Coating Standards: AA-M12C22A (US) or GB/T 5237.2-2017

• Laser marking (product tracing)
• Online thickness gauges (QC inspection)
• MES integration (production data analytics)

• Architectural aluminum (curtain walls, doors/windows)
• Automotive components (battery trays, heat sinks)
