1500T/M Fully Automatic Aluminum Anodizing Line for Solar PV Frames | Vertical Loading Mode, 10–15μm Natural Anodizing & Ambient Temperature Sealing

This 1500T/M fully automatic anodizing line adopts vertical loading design for long solar aluminum profiles. It delivers stable 10–15 μm natural oxide film and adopts ambient temperature sealing to meet outdoor anti-corrosion standards. Vertical layout optimizes land utilization with clear requirements on workshop depth for factory planning in advance.

1. Long aluminum profile vertical loading and fixture clamping
2. Degreasing to remove extrusion oil and surface contaminants
3. Mild alkaline etching to homogenize surface texture
4. Neutralization rinsing to eliminate alkaline residues
5. Multi-stage counter-current pure water cleaning
6. DC anodizing to form 10–15 μm natural oxide film
7. Multi-stage water rinsing after oxidation
8. Ambient temperature sealing treatment to enhance weather resistance
9. Final rinsing and air drying
10. Offline film thickness inspection and stacking

Q1: Why adopt vertical loading for PV frame anodizing?

A: Vertical hanging avoids bending and scratch of long aluminum profiles, ensuring uniform film thickness along the whole workpiece.

Q2: Does vertical loading mode have special requirements on factory workshop depth?

A: Yes. The required workshop depth depends on your maximum profile length. We will output accurate civil dimension parameters after confirming product specifications.

Q3: Can the line keep film thickness steadily within 10–15μm during long-term continuous running?

A: Closed-loop parameter control ensures stable film thickness, reducing fluctuation in mass continuous production.

Q4: Can this production line be upgraded to anodizing plus electrophoresis integrated line later?

A: The tank layout reserves expansion space. We can extend electrophoresis stations upon customer demand.

Q5: What wastewater supporting facilities are recommended to match this PV anodizing line? A: We provide matched wastewater treatment and optional waste acid recovery system to achieve environmental compliance.
