FAQ

Questions OEM Buyers Ask Us

What is your minimum order quantity?
There is no strict MOQ. Prototype orders from 1 piece are welcome; for production orders our pricing becomes most competitive from 100+ pieces.
What tolerances can you actually hold?
Our standard tolerance is ±0.05mm; ±0.01mm is achievable depending on geometry, feature size and material. Your quote will state the guaranteed tolerance for each feature — we never overpromise.
How fast can I get a quote?
Within 24 hours on working days. Complex assemblies may take up to 48 hours — if so, we'll tell you immediately and share a preliminary price range.
Will you sign an NDA before we send drawings?
Yes. Send your NDA template or use ours. We sign before any technical files are exchanged, and drawings are deleted from our servers on request.
Do you provide inspection reports?
Every shipment includes a dimensional inspection report. CMM reports, material certificates and full first-article inspection (FAI) reports are available on request.
What file formats do you accept?
STEP, IGES, STL, XT, DWG, DXF and PDF drawings. If you only have a sketch or sample part, our engineers can help create drawings first.
