3. Core Technical Advantages

1. Superior Surface Finishing Quality

   
   

   Vertical hanging full immersion structure makes electrolyte circulate evenly around aluminum profiles, no dead angle of treatment. Oxide film thickness deviation is controlled within ±1μm, completely avoiding scratches and contact marks common in horizontal lines, ideal for high-end decorative aluminum materials.
2. Ultra-High Production Capacity & Space Saving

   
   

   Under the same workshop area, the output of vertical anodizing line reaches up to 4 times that of horizontal equipment; vertical layout occupies only 50% floor space of horizontal lines with equal capacity, perfectly suitable for factories with limited plant area.
3. Low Consumption & Eco-Friendly Operation

   
   

   Vertical drainage reduces electrolyte drag-out loss by 25%, cutting water, acid and chemical consumption significantly. Matched self-developed sulfuric acid recovery system lowers waste neutralization expenses and meets global environmental emission requirements. High-frequency rectifier saves over 10% power compared with traditional power supplies.
4. Fully Intelligent Automatic Control

   
   

   Gantry crane runs with frequency conversion speed regulation, supporting automatic, semi-automatic and manual three operation modes. 24-hour real-time monitoring of temperature, current, time and liquid level; automatic dosing and online film thickness detection, minimizing manual operation and human error.
5. Durable Anti-Corrosion Structure & Customizable Design

   
   

   All liquid-contact parts adopt thickened PP and FRP anti-corrosion materials, resisting long-term erosion of high-concentration sulfuric acid with long service life. Tank length, load capacity and processing flow can be tailor-made to match customer production demands.
