Frequently asked questions.

Upload an STL to our instant quote tool for an immediate estimate with automatic geometry analysis. A firm, engineer-reviewed quote — with free DFM feedback — follows within 24 hours.

No. We produce anything from a single prototype to full production runs of 100,000+ parts. Pricing scales down with quantity.

Upload your CAD for a quote, choose material, finish, quantity and lead time, then approve. We begin manufacturing and ship — no account required to get started.

Yes — a free DFM review comes with every quote, flagging thin walls, deep pockets, stress risers and tool-access issues before we cut.

Yes. We routinely run a paid first article with a full inspection report (FAIR) so you can validate the part and process before a production order.

STEP, STP, IGES/IGS, SLDPRT, X_T/X_B, OBJ, 3MF, DWG, DXF, PDF and ZIP, up to 50 MB. STL files get an instant 3D preview and auto-measurement; other formats are reviewed by our engineers.

That's fine — send a PDF, DWG or DXF drawing and our engineers will review it and quote. A 3D model plus a 2D drawing of the controlled dimensions is ideal.

Yes. We sign a non-disclosure agreement on request before you share anything sensitive. Your files are used only for quoting and production.

State a general-tolerance block (e.g. ISO 2768-m) and tighten only the features that mate or seal. See our reference charts and design tips.

CNC machining (3/4/5-axis milling and turning), metal casting, forging, sheet metal & stamping, plastic injection molding, surface treatment, precision gears, custom fasteners and additive manufacturing — see capabilities.

Parts default to ISO 2768 general tolerances. Critical features are held to ±0.005 mm and CMM-verified. See the tolerance chart.

Roughly 800 × 600 × 500 mm for milling and Ø300 × 500 mm for turning, depending on material and process. Larger parts are possible — ask our team.

From one-off prototypes to mid- and high-volume production of 100,000+ parts, with the process matched to your volume and cost target.

Prototypes in about 5–10 business days, small batches in 2–3 weeks. Expedited service is available — confirmed with your quote.

Aluminium, stainless, carbon, alloy and tool steels, titanium, brass and copper, plus engineering plastics including ABS, nylon, POM, polycarbonate and PEEK. Browse materials for properties.

Yes. Beyond our stocked range we source specialty alloys and custom formulations — tell us your requirement.

As-machined, bead blasting, anodising (clear, hard, colour), black oxide, electroless nickel, zinc and chrome plating, passivation, powder coating and polishing, among others.

Yes — full material certification is provided on every order, with heat-lot traceability where required.

Our processes run to ISO 9001, IATF 16949, AS9100D and ISO 13485 quality systems — see quality.

Material certificates, First Article Inspection reports (AS9102), PPAP packages, CMM dimensional reports, NDT results and certificates of conformance — on request.

Yes — incoming material verification, in-process dimensional checks, first-article inspection and final inspection, with CMM verification on critical features.

Yes. We maintain material and heat-lot traceability so every part can be tied back to its raw stock and process.

Yes — we deliver to 40+ countries, with DDP shipping available so duties and customs are handled for you.

Parts are inspected, documented and packaged appropriately for safe international transit; sensitive designs stay confidential throughout.

Yes. Files are used only for quoting and production, never shared, and we sign an NDA on request before you send anything sensitive.
