How long does a custom order take?

Custom orders will require additional days or weeks depending on your order quantity and design complexity.

We recommend placing a small trial batch first before committing to bulk production — especially when drawings or designs have not yet been fully finalized.

Pricing depends on the following factors:

  • Type of processing (CNC / Laser / Printing)
  • Number and complexity of holes/cutouts
  • Surface finishing selected
  • Order quantity

What is the difference between anodizing and powder coating?

Comparison Anodizing Powder Coating / Spray Paint

Color Options Silver / Black / Gold / Custom dye Full RAL color range

How is anodizing quality controlled?

Our anodizing process follows strict quality control checkpoints:

  • Film Thickness: 8–10μm 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
