Fully Automated Aluminum Anodizing & E-Coating Line for Automotive Components
Our fully automated anodizing and electrophoretic coating line is engineered for high-performance surface treatment of automotive aluminum components. By integrating anodizing, electrolytic coloring, E-coating, sealing, and curing into one continuous production system, the line delivers outstanding corrosion resistance, uniform appearance, and long-term durability required by modern automotive manufacturers.
Integrated Surface Treatment Process
The production line combines multiple treatment stages within a fully automated workflow:
Each stage is precisely controlled to ensure consistent oxide film formation and stable coating quality across large production volumes.
High-Efficiency Anodizing Section
The anodizing area features multiple large-capacity tanks of approximately 4300 L each, supported by:
This configuration maintains stable electrolyte conditions and produces uniform anodic films with excellent appearance consistency.
Integrated Electrophoretic Coating System
Following anodizing, components enter a fully integrated E-coating section equipped with:
-
Electrophoretic coating tanks
-
Ultrafiltration (UF) systems
-
Paint recovery and refining units
-
High-efficiency curing ovens
The process provides uniform film thickness, excellent adhesion, enhanced weather resistance, and superior corrosion protection while maximizing paint utilization efficiency.
Advanced Sealing Technology
To further improve durability, the line supports multiple sealing methods:
Combined with multi-stage deionized water rinsing, these processes significantly enhance coating compactness and long-term surface stability.
Water Treatment & Environmental Management
The system includes a complete water purification and recycling solution featuring:
Separate wastewater collection for acidic, alkaline, fluoride-containing, and E-coating wastewater helps meet stringent automotive environmental standards.
Industrial-Grade Equipment Configuration
Key equipment includes:
-
30–40 T/H filtration systems
-
Industrial cooling systems
-
