Fully Automatic Small Aluminum Parts Anodizing Line | Custom Mini Oxidation Equipment Manufacturer – Guangdong Mei-Al Technology

GUANGDONG MEL-AL TECHNOLOGY COM., LTD.

Guangdong MEI-AL supplies modular small aluminum parts anodizing lines for electronic hardware, precision CNC components & aluminum fittings. PLC intelligent control, uniform oxide film, energy-saving acid recovery, full custom design, ISO & environmental compliant. Contact us for one-stop surface treatment solutions.

Our small aluminum parts anodizing line is specially engineered for mass processing of miniature precision aluminum workpieces, solving industry difficulies such as uneven film thickness, part falling off racks, high chemical consumption and low automation in traditional mini oxidation equipment.

Designed with skid-mounted modular architecture, this complete oxidation line covers full-process workflow: pre-treatment → sulfuric acid anodizing → dyeing/electrolytic coloring → multi-stage rinsing → nickel-free sealing → waste liquid recycling. It supports Type II decorative anodizing and Type III hard anodizing for tiny aluminum components ranging from electronic connectors, CNC hardware, aluminum housings, jewelry fittings to auto micro parts.

As a professional aluminum surface treatment equipment manufacturer, GUANGDONG MEI-AL integrates independent R&D, precision manufacturing, on-site installation, commissioning and global after-sales service, delivering stable, low-operation-cost and eco-friendly oxidation production lines for surface treatment factories worldwide.

Our small parts oxidation line adopts independent detachable modules for flexible layout, easy maintenance and later capacity expansion. Every module is built with anti-corrosion FRP & thick PP materials to extend service life.

• Custom multi-layer hanging racks & barrel jigs for tiny parts, preventing shedding during chemical circulation
• Adjustable automatic crane conveying system with variable speed control, matching short process cycles of mini components
• Low carry-over design reduces chemical waste and improves rinsing efficiency

Degreasing → alkaline etching → neutralization → multi-stage countercurrent pure water rinsing
Removes oil, oxide skin and burr residues to guarantee tight adhesion of oxide film, eliminating spot & color difference defects on small parts surface.

• Constant current/voltage rectifier power supply, temperature precision control ±0.5℃
• Adjustable oxide film thickness: 5μm–25μm, meets decorative and wear-resistant hard anodizing standards
• Internal circulation stirring system ensures uniform electrolyte distribution for consistent film on every tiny workpiece

• Support organic dye coloring (black, silver, gold, blue, red, purple) & inorganic electrolytic coloring
• Medium/high temperature nickel-free sealing tank, compliant with global environmental regulations, enhances corrosion resistance of finished small parts

Self-developed ion exchange sulfuric acid recovery system with up to 85% acid recycling rate, sharply cutting raw material cost and waste discharge. Matched water treatment unit satisfies international industrial emission standards, ideal for overseas factory certification audit.

Touch screen HMI automatic operation, programmable one-click process recipe switching for different aluminum alloys & small part batches. Real-time monitoring of temperature, liquid concentration, current and time, with automatic fault alarm & full production data traceability, minimizing manual operation errors.

1. Specialized Design for Mini Aluminum Workpieces
   Customized fixture solutions solve the universal problem of small lightweight parts floating, stacking and incomplete oxidation; multi-piece simultaneous processing greatly boosts single-batch output efficiency.
2. Ultra-Stable Oxidation Quality with Zero Color Difference
   Precise constant temperature & circulation technology eliminates uneven film thickness on thin, tiny components, consistent appearance across mass production batches, passing strict third-party quality inspection.
3. Energy & Chemical Saving, Lower Total Operation Cost
   Energy-efficient refrigeration unit + high-rate acid recovery system reduces electricity and sulfuric acid consumption by 30% compared with traditional small oxidation lines; countercurrent rinsing cuts water waste by over 40%.
4. Compact Modular Layout, Small Floor Space Occupation
   Skid-mounted integrated structure saves workshop area, convenient for old factory renovation and new plant construction; split modules support containerized export and quick on-site assembly.
5. Full Customization Support
   Adjust tank size, automation level, process modules, fixture forms according to your workpiece dimension, daily output and local environmental requirements; provide semi-automatic and fully automatic two configurations for different budget demands.
6. Long Service Life & Low Maintenance Cost
   Whole tank body adopts thickened anti-corrosion PP & FRP, resistant to strong acid and alkali; key electrical and power components use imported brands, reducing downtime maintenance frequency.
