FAQ
|
Q1: |
What is the minimum order quantity? |
|
A1: |
We accept prototype orders starting from 1 piece. For mass production, MOQ depends on part complexity, typically 100–500 pieces. |
|
Q2: |
Can you work from a physical sample instead of a drawing? |
|
A2: |
Yes. We can reverse-engineer from your sample and provide a 3D model and drawing for your approval before production. |
|
Q3: |
What surface finishes do you offer? |
|
A3: |
We offer as-machined, bead blasted, brushed, electropolished, and mirror polished finishes. Custom treatments are available upon request. |
