CNC Machining in China
Supplier tiers, realistic tolerances, material certification and the cheap-quote trap.
Read the guide →Each domain is run through vetted shops and held to the same technical gatekeeping. The differentiator isn't any single process — it's that they're planned, inspected and landed together.
Fiber laser cutting, CNC bending, welding and powder coating in one flow — from flat pattern to finished enclosure.
3/4/5-axis milling and turning across a vetted network — one-off prototypes through batch production.
Aluminum die casting with tooling and machining planned together — porosity managed, not discovered at assembly.
Custom dies and profile extrusion, then precision cutting and machining — die to finished part in one chain.
Engineering review on every project — FEA stress/thermal analysis and manufacturability checks, via a partner simulation engineer.
Practical guides on supplier tiers, tolerances, tooling and the landed-cost traps — written for buyers, not sales.
Supplier tiers, realistic tolerances, material certification and the cheap-quote trap.
Read the guide →When to cast instead of machine, tooling cost vs volume, and keeping porosity out of the part.
Read the guide →Custom dies, 6063/6061 profiles, secondary machining and finishes.
Read the guide →Laser, bend, weld and powder coat in one flow — design rules and avoiding weld distortion.
Read the guide →Every project passes the same gates before it ships.
Tolerance, draft, material and process fit reviewed up front — fixes cost cents here, not thousands later.
Critical dimensions and material grade written into the order, not left to chance.
FAI on the first parts against the drawing — approved before volume runs start.
Checkpoints during production, not just at the end — non-conformance caught early.
Final inspection, photos and the paperwork (CoC, inspection report, customs docs) packed with the parts.
Factory price, my fee and Incoterms confirmed up front so the number you approve is close to what you pay.
| Standard | What you receive |
|---|---|
| Dimensional | Inspected to drawing; FAI report on first article, spot checks on the run. |
| Material | Mill certificate / composition on request; grade confirmed before cutting. |
| Surface finish | Per spec (anodize, powder, passivate); photo record of representative parts. |
| Packaging | Export-grade, damp-proof, labeled — arrives usable, not scuffed. |
| Documentation | Certificate of Conformance, inspection report and customs paperwork included. |
| Traceability | Lot / batch recorded; non-conformance handled, not hidden. |
| Landed | Delivery terms and Incoterms confirmed up front — no surprise at the dock. |
Compatible products already delivered — furniture and LED (done for a US end-user). Depending on your market, these may carry local requirements (for example CE / RoHS / WEEE for LED, EN fire rating and packaging rules for furniture) — worth confirming what applies in your market before we start.
