Automatic Aluminum Anodizing Line with PLC Automatic Control and 8-12µm Film Thickness Turnkey Solution

Our fully automatic aluminum anodizing line is a turnkey surface treatment solution tailored for aluminum profiles, die-cast parts, PV frames, and automotive aluminum components. Featuring high-precision constant-temperature control and pulse rectifier technology, this line delivers stable anodizing quality, low production reject rates, and energy-saving operation. Equipped with complete environmental protection systems, it fully complies with global environmental policies and factory audit standards, providing one-stop customized production solutions for industrial aluminum processing enterprises.

• Eliminate uneven oxide film thickness and color deviation, ensuring stable salt spray test performance
• Prevent common defects such as white spots, hook marks, and powdering on die-cast aluminum parts
• Reduce power, water, and chemical consumption to minimize long-term operating costs
• Enable standardized automatic production, reducing dependence on skilled workers
• Support flexible switching of multiple processes for multi-variety and small-batch production
• Complete environmental protection configuration to avoid environmental assessment and production shutdown risks

1. Loading: Workpiece hooking
2. Pre-treatment: Degreasing → Alkali etching → Neutralizing & desmutting
3. Anodizing: Form protective oxide film under current
4. Coloring (optional): Dyeing process
5. Sealing: Improve corrosion resistance
6. Unloading, rinsing, inspection & finished output
