360T/M Output | Mini Anodizing Line | Compact Aluminum Anodizing System for Small Batch Production

Guangdong MEI-Al Technology Co., Ltd. designs and manufactures premium mini anodizing lines — compact, fully functional anodizing systems built specifically for small-volume aluminum surface treatment, research and development, and low-scale production operations. Based in Foshan, China’s core aluminum extrusion manufacturing hub, we deliver reliable, budget-friendly small anodizing equipment that retains full process capability while minimizing floor space and initial investment.

Ideal for aluminum hardware, decorative components, prototype development and laboratory testing, our mini anodizing production lines deliver consistent, industrial-grade anodizing quality in a space-efficient, easy-to-operate package.

Engineered for facilities with limited workshop space, our small anodizing system features a streamlined linear layout that fits into tight production areas or laboratory environments. The compact design eliminates redundant structure while preserving full process functionality, making it perfect for small workshops, R&D centers and new production lines in their initial phase.

Compared with full-scale vertical anodizing lines, our mini anodizing line requires significantly lower capital expenditure and operational costs. It reduces chemical consumption, energy usage and labor input, making it an economical choice for small batch production, product testing and process validation — without compromising on finishing quality.

Despite its compact size, the system supports the full aluminum anodizing process chain, including degreasing, etching, anodizing, optional coloring and sealing. It produces uniform, corrosion-resistant oxide layers that meet the same quality standards as large-scale production lines, suitable for both functional and decorative aluminum parts.

Every mini anodizing system is tailored to your specific requirements: tank quantity, dimensions, power capacity and automation level can all be customized to match your part size, output volume and process needs. We offer both manual and semi-automatic control options to fit your operation scale and budget.

The line is equipped with our proprietary high-power silicon controlled rectifier (SCR) power supply, scaled to match small-batch production requirements.

• Current range from 1KA to 3KA, fully adjustable to part load
• Output voltage 0–24V DC, with voltage and current stability accuracy below 1%
• Built-in overheat, over-current, under-voltage and phase-loss protection
• Air-cooled design for reliable, continuous operation with low maintenance

All process tanks are constructed from high-grade corrosion-resistant PP/PVC materials, engineered for long service life with acidic and alkaline process chemistries. Tank dimensions and quantity are fully customized based on your workpiece size and process flow.

• Manual mode: Simple, intuitive operation for small-batch and trial production, with low operator training requirements
• Semi-automatic mode: PLC-based timing control for consistent process cycles, with manual override for flexible operation

• Chilling unit with plate heat exchanger for precise bath temperature control
• RO pure water system for high-quality sealing and spot-free surface finish
• Acid mist exhaust treatment system for environmental compliance and workplace safety
• Filtration and circulation systems to maintain bath solution quality

1. Loading — Manual racking of small aluminum parts and profiles
2. Degreasing — Alkaline cleaning to remove oils, grease and surface contaminants
3. Alkali Etching — Sodium hydroxide etching to remove native oxide and prepare surface texture
4. Desmutting — Acid pickling to eliminate intermetallic smut and activate the aluminum surface
5. Anodizing — Electrochemical formation of protective porous oxide layer in sulfuric acid electrolyte
6. Coloring (Optional) — Electrolytic coloring for decorative bronze, black and champagne finishes
7. Sealing — Hot water or nickel-salt sealing to close oxide pores and improve corrosion resistance
8. Unloading — Final rinse and part discharge for inspection
