FAQ
What is your MOQ?
MOQ depends on the part, material, and process. Prototype and small batch orders can be reviewed.
What is your lead time?
Lead time depends on material availability, quantity, finishing, and inspection requirements. We usually reply within 24 hours after reviewing your drawing.
Do you support prototypes?
Yes. We can review prototype, small batch, and repeat production requirements from drawings or samples.
What materials do you work with?
Common materials include stainless steel, carbon steel, alloy steel, aluminum, brass, copper, bronze, and engineering plastics.
Can you machine tight tolerance parts?
Yes, but tight tolerance depends on geometry, material, part size, and inspection method. Critical dimensions should be marked clearly.
