Thông tin chi tiết
Mô tả sản phẩm

1. Product Introduction

The automatic vertical aluminum anodizing line developed by GUANGDONG MEI-AL TECHNOLOGY CO., LTD. is a high-precision industrial surface finishing solution tailored for extra-long aluminum profiles, solar aluminum frames, architectural extrusion materials and large aluminum structural parts. Adopting gantry crane vertical hanging and full immersion processing technology, this equipment effectively avoids surface contact marks and uneven oxidation issues of traditional horizontal lines. With integrated automatic pretreatment, anodizing, coloring, sealing and acid recycling modules, the line realizes standardized, stable and eco-friendly mass production.

3. Line Configuration Composition

The vertical anodizing production line adopts modular integrated design, covering the complete aluminum surface finishing process:
  • Automatic Loading & Unloading System: Gantry frequency conversion control, stable lifting and precise positioning to ensure continuous batch production.
  • Pretreatment Module: Complete degreasing, alkaline etching, neutralization and multi-stage rinsing to guarantee ultra-clean workpiece surface before oxidation.
  • Vertical Sulfuric Acid Anodizing Module: Constant-temperature circulating tank body ensures uniform electrolyte distribution for high-precision oxide film formation.
  • Electrolytic Coloring & Sealing Module: Steady current and voltage control ensures uniform color and excellent weather resistance of finished products.
  • Acid Recovery System (Optional): Adopts professional ion exchange technology to recycle waste sulfuric acid, reduce production costs and achieve green production.
  • Intelligent PLC Control System: Real-time monitoring of temperature, time, current and liquid level to realize unmanned automatic operation.

4. Product Advantages

  • High Finishing Quality: Vertical full immersion processing eliminates contact scratches and dead-angle treatment problems, ensuring high uniformity of oxide film and color.
  • Space-Saving & High Efficiency: Compact vertical layout saves workshop space and greatly improves single-shift output, suitable for large-scale standardized production.
  • Energy & Cost Saving: Low liquid carry-over loss reduces chemical and water consumption. Matching acid recovery system further lowers operating and waste disposal costs.
  • Strong Durability & Stability: Full anti-corrosion structure adapts long-term strong acid working environment, reducing equipment failure and maintenance frequency.
  • High Customization: Workpiece length, tank size, production capacity and functional modules can be customized according to customer factory conditions.

5. Application Range

This vertical anodizing line is widely applied in standardized surface treatment of aluminum products, including solar energy aluminum frames, architectural curtain wall profiles, industrial aluminum extrusions, new energy auto aluminum parts and high-end decorative aluminum materials.
