Automatic Aluminum Anodizing Line for Precise Surface Treatment and Consistent Color Finishing with Full Automatic Operation

Standardized full-automatic workflow ensures zero-defect cosmetic aluminum bottle surface quality and perfect color consistency:

1. Precision loading: Professional hanging fixture design to avoid bottle surface scratches and conductive dead zones
2. Ultra-clean pre-treatment: Multi-stage degreasing and etching to remove surface oil, oxide and fingerprint residues
3. Balanced neutralization: Eliminate surface ash and ensure uniform adsorption for subsequent dyeing
4. Constant-current anodizing: Form uniform and dense oxide film on curved bottle surfaces
5. Precision coloring: Realize consistent matte, bright and customized color finishing
6. High-quality sealing: Improve corrosion resistance and prevent color fading and surface whitening
7. Purified rinsing & quality inspection: Remove residual chemicals and confirm flawless surface
8. Finished product unloading and packaging: Avoid secondary pollution and surface abrasion
