Fully Automatic Aluminum Anodizing Production Line with Modular Design and 5-25μm Film Thickness

GUANGDONG MEI-AL TECHNOLOGY CO., LTD. is a professional manufacturer and solution provider of industrial aluminum surface treatment equipment. We specialize in the research and development, production, installation and one-stop after-sales service of high-performance aluminum anodizing production lines.

Our integrated anodizing system covers full-process operations including pre-treatment, sulfuric acid anodizing, electrolytic coloring, hole sealing and waste acid recycling. We deliver comprehensive surface finishing solutions for aluminum profiles, automotive aluminum parts, architectural aluminum materials and precision hardware accessories.

Compared with traditional semi-automatic oxidation equipment, our upgraded anodizing production line adopts standardized modular design and intelligent control system to optimize common production issues in the industry, such as uneven oxide film thickness, high chemical consumption, excessive waste discharge and high manual reliance.

Our complete aluminum anodizing production line integrates multiple core functional modules to achieve fully closed-loop automatic production:

• Pre-treatment Module: Consists of degreasing, alkaline etching, acid neutralization and pure water cleaning processes
• Sulfuric Acid Anodizing Module: Adopts mature low-temperature oxidation technology with adjustable film thickness from 5μm to 25μm
• Electrolytic Coloring & Dyeing Module: Supports various color options with constant current and voltage control
• Hole Sealing Module: Applies high-temperature or medium-temperature nickel-free sealing technology
• Waste Acid Recovery & Sewage Treatment Module: Equipped with self-developed ion exchange sulfuric acid recovery systems

• Intelligent Automatic Control System: PLC centralized control with programmable operation interface
• Stable Oxidation & Consistent Quality: Optimized tank circulation and power rectification technology
• Energy Saving & Low Operational Cost: Energy-saving refrigeration units with up to 85% sulfuric acid recovery rate
• Superior Corrosion Resistance & Long Service Life: High-quality PP and FRP anti-corrosion materials
• Flexible Customization & Easy Installation: Integrated modular skid-mounted structure

MEI-AL Technology's aluminum anodizing production lines are widely applied in various aluminum surface treatment industries:

• Anodizing treatment for architectural aluminum profiles
• Oxidation processing for automotive aluminum alloy parts
• Surface treatment for industrial aluminum profiles and precision components
• Anodizing for decorative aluminum hardware and electronic aluminum shells
• Hard anodizing for mechanical anti-corrosion and wear-resistant aluminum parts

As a reliable Chinese manufacturer of aluminum surface treatment equipment, we integrate independent R&D, precision manufacturing, on-site installation and global after-sales services. We focus on improving production stability, operational efficiency and environmental compliance for anodizing factories.

We provide one-stop customized solutions, including process design, equipment manufacturing, on-site commissioning, operator training and long-term technical support. All equipment complies with international industrial standards and supports full export certification.
