Custom CNC Machining & Sheet Metal Fabrication — ISO 9001 Certified China Factory

Our minimum order quantity is 1 piece for all services — CNC machining, laser cutting, sheet metal bending, welding, and stamping. We regularly produce single prototype pieces and scale the same quality system to production runs of 10,000+ units. For prototype orders of 1-5 pieces, our standard lead time is 3-7 business days. There is no setup or programming fee charged separately for low-volume orders — the cost of DFM review, CNC programming, and first-article inspection is included in the part price

Standard CNC machining tolerance is +-0.05mm (ISO 2768-m). For precision applications, we regularly hold +-0.01mm (ISO 2768-f) on critical features using our 5-axis machining centers, verified by Hexagon CMM. Surface roughness ranges from Ra 0.4 to Ra 3.2 as-machined, with Ra 0.2 achievable through polishing. All precision lot shipments include a CMM dimensional inspection report with actual vs. nominal values for every critical feature. For aerospace, medical, and tight-tolerance industrial applications, we recommend submitting drawings for a DFM review before quoting.

We return quotations within 24 hours for standard CNC and sheet metal parts. To quote accurately, we need: a 2D drawing in PDF or DXF format (or a 3D STEP file), the material specification including grade, the target quantity, and tolerance requirements for critical features. If your drawing includes surface finish callouts or compliance requirements (RoHS, REACH, PPAP), please include those as well. Our DFM review is included with every quotation at no charge — we identify any design features that may affect cost or lead time and flag them in writing before you commit to an order.
