Send a drawing or a sample — get a manufacturability review and a firm quote.
ViewSTEP (.stp/.step) or IGES (.igs) for 3D, PDF or DWG for 2D drawings with tolerances and surface finish. If you only have a physical sample, we can reverse-engineer it — and a photo with the key dimensions is enough for a budget estimate.
Standard machining tolerance is ±0.05 mm, and ±0.01 mm on features you mark as critical. Locating bores can be held to H7. Tell us which dimensions actually matter — over-tolerancing is the fastest way to raise cost without improving the part.
No. We machine one piece as readily as one thousand. Unit price improves noticeably at 50, 200 and 1,000 pieces because setup and programming amortise, and we use the same programme and fixtures from prototype through to series.
Quotes are returned within 24 working hours, usually the same day for simple parts. Production lead time is typically 7–20 working days depending on complexity, material availability and finishing.
