How is anodizing quality controlled?

Our anodizing process follows strict quality control checkpoints:

Film Thickness: 8–10 μm for decorative use; 18–25 μm for corrosion/outdoor applications
Color Uniformity: ΔE ≤ 1.0 to ensure consistent coloring across batches
Sealing Quality: Dye fade test ≤ 3% / Salt spray test ≥ 336h (ASTM B117)
Adhesion: Cross-cut test Grade 0–1 (ISO 2409)
Visual Inspection: No scratches, white spots, residue or mold spots at 50 cm viewing distance
