100 TPM Vertical Anodizing Line | Window & Solar Frame Aluminum Profiles – Guangdong MEI-AL Technology

MEI-AL 100 ton/month vertical anodizing line is engineered for aluminum window & door profiles and solar PV frames. Uniform film thickness, weather-resistant finish, PLC automatic control and compact layout for small & medium capacity plants. Custom turnkey anodizing solutions for architectural & photovoltaic aluminum manufacturers.

This vertical anodizing line is purpose-built for small-to-medium aluminum profile manufacturers with a rated monthly output of 100 tons, dedicated to the anodizing treatment of architectural window & door profiles and solar photovoltaic (PV) frame profiles.

Adopting a vertical hanging structure, the line ensures consistent film thickness and uniform quality across full-length profiles. It balances decorative appearance requirements for window products and high weatherability / corrosion resistance requirements for solar frames. With compact layout, controlled investment cost and stable operation, it is an ideal solution for small and medium aluminum plants entering the architectural and photovoltaic sectors.

As a professional aluminum surface treatment equipment manufacturer with over 10 years of experience, GUANGDONG MEI-AL delivers tailored turnkey anodizing solutions aligned with actual production scale and product application requirements.

• Suitable for residential and commercial aluminum window & door profiles, curtain wall sections and decorative aluminum materials
• Supports classic finishes including natural silver, champagne, bronze and black
• Tight color difference control and high batch-to-batch consistency, meeting architectural decorative appearance standards
• Reliable corrosion resistance for long-term outdoor building application

• Optimized for long-term outdoor service of solar module frames
• Dense and uniform anodic oxide film with excellent weatherability, UV resistance and salt spray corrosion resistance
• Meets the reliability and service life requirements of the photovoltaic industry
• Stable film thickness control ensures consistent mechanical and protective performance across mass production

1. Pre-treatment: Degreasing → Alkaline Etching → Neutralization → Multi-stage Countercurrent Rinsing
2. Core Process: Sulfuric Acid Anodizing → Electrolytic Coloring (optional)
3. Post-treatment: Multi-stage Pure Water Rinsing → Nickel-free Sealing → Drying

1. Vertical Hanging for Uniform Full-Length Quality

   Vertical workpiece hanging ensures full and uniform contact between profile surfaces and electrolyte. For standard 6–7 meter profiles, film thickness and coloring effect remain consistent from top to bottom, eliminating upper-lower color difference and uneven film thickness defects common in horizontal lines.

2. Precision-Tuned 100 TPM Capacity, High ROI

   Tank volume, crane cycle and process rhythm are all optimized for 100 tons monthly output, with no redundant capacity. This allows controlled equipment investment, shorter payback period and higher operational efficiency, perfectly matching the production scale of growing small and medium manufacturers.

3. PV-Grade Protective Performance

   Process parameters are optimized for solar frame outdoor service requirements. The anodic oxide film features low porosity and excellent sealing quality, delivering outstanding salt spray resistance, weatherability and anti-aging performance to support 25+ year service life of photovoltaic modules.

4. Architectural-Level Appearance Consistency

   Equipped with high-precision coloring power supply and bath concentration control system, the line delivers strict batch-to-batch color difference control. Mainstream decorative finishes perform stably and reliably, satisfying the high appearance standards of architectural window and door products.

5. PLC Fully Automatic Control

   Integrated PLC central control system realizes fully automatic operation of crane conveying, power output adjustment and process timing. Multiple sets of process recipes can be stored for one-click switching between window profile and solar frame production, reducing manual operation errors and labor intensity.

6. Compact Layout, Small Footprint

   Modular skid-mounted structure with optimized workshop layout occupies less floor space. It is highly adaptable to both new plant construction and existing workshop renovation projects, reducing site investment cost.

7. Energy-Saving & Environmentally Compliant

   Multi-stage countercurrent rinsing reduces water consumption by more than 40%. Optional acid recovery system and acid mist treatment unit further cut chemical consumption and exhaust emission, fully complying with international environmental protection standards.
