Q1What is the standard tolerance for your aluminum extrusion profiles? Can you do high precision?
Our standard tolerance complies with DIN EN 755-9 or GB/T 5237. For normal sections, we control at ±0.1mm.
Q2How to obtain a quotation?
24-hour online quotation based on drawings (supporting PDF/DWG/STP/STEP files) or samples.
Q3Do you charge tooling/mold fee for custom aluminum profiles? What is the MOQ?
Yes, there is a one-time tooling fee for new dies. But there is no minimum order quantity restriction.
Q4What surface finishing options do you offer? (Anodizing, powder coating, wood grain?)
We provide a one-stop finishing service:
• Anodizing: Silver, Black, Gold, Champagne (Matte or Bright)
• Powder Coating: RAL colors, texture or glossy
• Electrophoresis: For high corrosion resistance
• Sandblasting & Mechanical Polish
We also offer CNC machining (drilling, tapping, milling) before finishing.
Q5What is your lead time for custom extrusion tooling and mass production?
Tooling (Die making): 7-15 days (depending on complexity)
Sample production: 3-5 days after die approval
Mass production: 15-25 days after sample confirmation.
