Description
Automatic Aluminium Anodizing Production Line for Outdoor Curtain Wall & Door Window Profiles
This dedicated anodizing line is engineered for architectural aluminium profiles for outdoor curtain walls, doors and windows. It delivers stable oxide film thickness above 20 μm to satisfy long-term outdoor weather resistance requirements.
Technical Specifications
Item Technical Parameter
Application Scope Outdoor architectural aluminium curtain wall, door & window profiles
Minimum Oxide Film Thickness ≥20 μm (adjustable up to 28 μm)
Coloring Technology Tin salt / Nickel salt electrolytic coloring
Sealing Process Medium-temperature nickel salt sealing, 60-80°C
Standard Color Range Champagne, Bronze, Dark Bronze, Black, Silver White
Recommended Alloy 6063, 6060 architectural aluminium alloy
Weather Resistance Compliant with outdoor construction aluminium profile standards
Operation Mode Overhead gantry automatic hanging production
Tank Material Thick anti-corrosion PP/PVC tank body
Control System PLC integrated automatic control of temperature, time and current
Production Process
  1. Aluminium profile loading and fixture clamping
  2. Degreasing to remove surface lubricants and pollutants
  3. Alkaline etching to achieve uniform matte surface
  4. Neutralization washing to eliminate alkaline residue
  5. Pure water rinsing to avoid cross-contamination of chemicals
  6. DC anodizing to form oxide film ≥20 μm
  7. Tin / nickel salt electrolytic coloring for target shade
  8. Multi-stage cascade pure water rinsing
  9. Medium-temperature nickel salt sealing at 60-80°C
  10. Final cleaning, air drying and offline quality inspection
Core Advantages
  • Stable film thickness ≥20 μm, effectively resisting outdoor UV radiation and acid rain erosion
  • Mature tin/nickel electrolytic coloring system ensures consistent color batch after batch
  • Medium-temperature nickel salt sealing improves corrosion resistance and reduces sealing stain risks
  • Optimized tank layout adapts to long architectural aluminium profile mass production
  • Stable wastewater discharge, easy to connect with supporting wastewater treatment facilities
Supporting Equipment
  • Gantry automatic travelling crane and long profile dedicated hangers
  • High-power DC stabilized anodizing rectifier
  • Constant temperature heating & cooling circulation system
  • Electrolytic coloring power supply unit
  • Medium-temperature sealing temperature control system
  • Multi-stage pure water recycling equipment
  • Automatic chemical dosing system
  • Wastewater treatment system for architectural surface treatment
  • Air drying workstation and inspection platform
Frequently Asked Questions
Is 20 μm film thickness compulsory for outdoor curtain wall profiles?
Most national architectural standards require ≥20 μm oxide film for outdoor exposure. We support thickness adjustment upon local building code requirements.
What is the difference between tin salt and nickel salt electrolytic coloring?
Tin salt delivers warm tones such as champagne and bronze; nickel salt performs better for dark bronze and black with superior UV stability.
Why adopt medium-temperature nickel salt sealing instead of hot water sealing?
Nickel salt sealing offers higher corrosion resistance for outdoor profiles and significantly lowers the risk of premature fading under outdoor conditions.
Can this line be upgraded to support electrophoresis coating in the future?
We provide optional modular extension. If you plan to launch electrophoresis later, you can select the integrated Anodizing + Electrophoresis line solution.
How to guarantee uniform color for long-length architectural profiles?
Equipped with circulating agitation systems in coloring tanks and stabilized power supply to avoid color difference between profile top and bottom.
