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

Aluminium profile loading and fixture clamping
Degreasing to remove surface lubricants and pollutants
Alkaline etching to achieve uniform matte surface
Neutralization washing to eliminate alkaline residue
Pure water rinsing to avoid cross-contamination of chemicals
DC anodizing to form oxide film ≥20 μm
Tin / nickel salt electrolytic coloring for target shade
Multi-stage cascade pure water rinsing
Medium-temperature nickel salt sealing at 60-80°C
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.
