Laboratory Anodizing Line – Specially Designed for Aluminum Alloys/MEI-AL Technology
Guangdong MEI-AL Technology Co., Ltd.
With over 10 years of experience in the industry, Guangdong Meilu Technology Co., Ltd. is located in Nanhai District, Foshan, a major aluminum industry base. We specialize in the R&D and manufacturing of complete surface treatment equipment for aluminum alloys, including anodizing, micro-arc oxidation and electrophoretic coating lines. We have served more than 500 enterprises and research institutions across the globe, providing one-stop solutions for laboratory research, sample trial production and mass production transfer.
Core Positioning
Our laboratory anodizing line is developed exclusively for aluminum alloy process R&D, parameter optimization, small-batch sampling and technical training. It supports full processes including conventional anodizing, hard anodizing, micro-arc oxidation, titanium & zirconium passivation, coloring and sealing. Featuring precise parameter control, flexible operation and stable sample quality, it is the ideal choice for enterprise R&D centers, university material laboratories and professional surface treatment labs.
Typical Applications
Process R&D: Test the impacts of current density, temperature, processing time and chemical formulas on aluminum oxide film, including film thickness (5-150μm), hardness and corrosion resistance (720-hour NSS test).
Sample Production: Manufacture customer samples and standard test pieces in small batches for performance testing and visual inspection. Single-piece processing is available.
Technical Training: Demonstrate the complete anodizing process and electrochemical principles. We also provide professional operation guidelines and process manuals.
Production Transfer: Apply proven laboratory parameters to mass production lines seamlessly, ensure consistent quality between R&D and volume production, and reduce trial costs.
Degreasing Tank: Made of PP material, equipped with air agitation and heating system (40-60℃) to fully remove oil stains and cutting fluid.
Alkaline Etching Tank: Adopts PVC material with temperature control at 50-70℃, used to remove natural oxide films and burrs. It is well suited for die-cast aluminum alloys such as A380 and ADC12.
Neutralization & Descaling Tanks: Special chemicals neutralize residual alkali and remove silicon and copper impurities to prevent coating defects.
Multi-stage Rinsing: Workpieces are cleaned with tap water and deionized water (conductivity ＜ 30μS/cm) to avoid cross-contamination.
Main Anodizing Section
Anodizing Tank: Thickened PP/PVC structure with excellent acid and alkali resistance. Equipped with adjustable cooling system (0-25℃), lead cathode plates and air agitation.
High-frequency DC Power Supply: Output range 0-50V / 0-20A with constant voltage and current control within ±0.1% tolerance. It meets the requirements of conventional anodizing (5-20μm) and hard anodizing (30-150μm) for aluminum alloys.
High-precision Temperature Control: Temperature accuracy reaches ±0.5℃, compatible with sulfuric acid anodizing, hard anodizing and micro-arc oxidation.
Post-treatment Section
Rinsing → Sealing → Drying → Inspection
Sealing Tank: Adopts hot water sealing (95-100℃) or chrome-free sealing agents to improve corrosion resistance, fully compliant with RoHS and REACH standards.
Drying Oven: Hot air circulation design. Low temperature mode (＜80℃) prevents thermal cracking of aluminum workpieces; high temperature mode (100-120℃) is used for sealing agent curing.
Inspection Station: Equipped with film thickness testers and salt spray chambers for integrated quality inspection.
Control System (Manual / Semi-automatic Optional)
Manual Type: Knob control for flexible parameter adjustment, suitable for formula research and testing.
Semi-automatic Type: Equipped with PLC and touch screen. It can store up to 50 sets of process formulas, with automatic timing and temperature linkage functions to guarantee stable batch quality.
Core Advantages
High Precision & Traceable Data
Current, voltage, temperature and time are digitally displayed and adjustable. The thickness deviation of oxide film is less than 5%, and surface roughness Ra ＜ 0.2μm. The equipment automatically records all process data to realize formula replication and production transfer, achieving full data traceability.
Dedicated for Aluminum Alloys with Full Process Coverage
Tailored for aluminum alloy processing. It integrates conventional anodizing, hard anodizing, micro-arc oxidation, chrome-free passivation, coloring and sealing into one unit.
Compact Size & High Cost Performance
Standard dimension: 1500*800*1200 mm. It occupies little floor space and fits perfectly in laboratories. The small-capacity tanks reduce chemical consumption and effectively cut down sampling costs.
