MEIAL Manual Anodizing Line, Compact Low-Cost PP Tank System for Small Batch R&D Samples & Multi-Color Prototyping

MEIAL manual anodizing line is tailor-made for small factories, R&D labs and prototype workshops. Low upfront cost, compact layout, full process including degreasing, caustic etching, neutralization, anodizing, dyeing, electrolytic coloring and sealing. Flexible manual operation supports frequent formula switching, stable 5–20μm oxide film. Matched with SCR rectifier, chiller, filter and full environmental waste gas/wastewater supporting devices, ideal for multi-variety small-batch aluminum alloy parts.

MEIAL manual anodizing line is modular independent tank equipment, fully covering the whole aluminum surface treatment workflow. Different from fully automatic traveling crane lines, each process tank relies on manual hoist/hand-held rack feeding, with fully independent adjustable process parameters. Operators can freely control soaking time, current and temperature to meet strict precision requirements of special-shaped parts, multi-color trial production and new formula R&D.

Matched with self-developed ML-YH silicon controlled rectifier, air-cooled water chiller, plate heat exchanger, circulation filtration system, air stirring blower and RO pure water unit, the line can stably produce decorative anodized film, hard anodized film, support organic bright gold dyeing & weather-resistant electrolytic champagne bronze coloring. Tank body adopts thick anti-corrosion PP plate, all pipeline valves are UPVC anti-acid & alkali accessories, durable under long-term acid mist workshop environment.

Complete supporting environmental equipment including three-acid mist absorption tower and wastewater treatment system, fully compliant with local environmental emission standards. Modular tank layout can customize tank size, station quantity and workpiece maximum length according to plant area and production volume, widely applied to 3C small hardware, small aluminum profiles, medical titanium parts, mold prototypes and small-batch customized workpieces.

1. Ultra-Low Investment & Fast Factory Deployment

   No expensive automatic traveling crane and PLC linkage control system, greatly reduce one-time equipment cost. Modular split structure with small overall footprint, suitable for small workshops and leased factories without large civil reconstruction, short installation cycle, quickly put into trial production.

2. Super Flexible for Multi-Variety, Small-Batch & R&D Samples

   Each process can be independently adjusted manually: soaking time, current density, bath temperature can be modified at will. Freely switch sand surface, bright surface, bright gold dye, electrolytic bronze black without fixed production procedures. Perfect for frequent sample testing, new alloy formula development and customized small batch orders that automatic lines cannot flexibly handle.

3. High Precision Surface Quality for Complex Special-Shaped Parts

   Operators can adjust hanging position, stirring strength and immersion angle according to workpiece structure, effectively solve film thickness unevenness, color difference, dead zone missing coating problems of deep hole, thin wall, irregular cast aluminum parts. Higher finished product precision than mass automatic lines for high-standard prototype products.

4. Complete Full-Process Matching, All Supporting Accessories Included

   Equipped with full set of MEIAL original supporting parts: oxidation rectifier, coloring power, chiller, plate heat exchanger, circulation pump, air agitation blower, filter, pure water equipment, manual elevator, cathode plate, anode beam, PVC/PP fittings. One-stop supply without scattered purchasing, unified installation and debugging guidance.

5. Anti-Corrosion Durable Structure, Low Daily Maintenance Cost

   Whole tank thick PP fusion welding without leakage; all pumps, pipes, gaskets are acid & alkali resistant special materials. Circulation filtration system reduces tank residue precipitation, extend service life of oxidation & coloring liquid, cut regular chemical replacement cost; simple manual structure, few moving parts, easy cleaning and overhaul.

6. Complete Eco-Friendly Supporting System, Pass Environmental Inspection Smoothly

   Can be matched with three-acid mist treatment tower to absorb workshop acid and alkali waste gas; supporting independent wastewater treatment equipment to treat acid, aluminum-containing and coloring heavy metal wastewater. Full set environmental solution helps customers smoothly pass EIA and routine environmental supervision inspection.
