CNC machining in China, without the usual supplier risk.
A 36-person shop in Dongguan, 32 machining centres, CMM first articles, 16-hour quotes. We tell you what we do not have — no ISO 9001, no 5-axis — before you send a drawing.
- 36 people, one building since 2008
- 32 machining centres, 19 four-axis
- ±0.002 mm critical features
- CMM first article, PDF report
- DDP, FOB or EXW — your choice
The real comparison: China vs a local shop
| GY Machining (Dongguan) | Local US/EU shop | |
|---|---|---|
| Typical machining rate | Lower labor and overhead | Higher hourly rate |
| Prototype lead time | 5–10 working days | Often 2–4 weeks in a busy shop |
| Minimum order | None | Often $500–$2,000 per order |
| Communication | One English-speaking engineer, 16-hour replies | Same time zone, easier calls |
| Certification | No ISO 9001 — stated up front | Usually ISO 9001 |
| Freight | DDP door to door available | Domestic, simple |
| Best fit | Prototypes, low volume, cost-sensitive production | Certified, high-volume, same-day support |
The honest answer: if your RFQ requires ISO 9001 or same-day engineering support, use a local certified shop. If it requires a prototype in two weeks at a workable price, we are built for that.
What we do not claim
No ISO 9001
We will not pretend to have a certificate. If your customer requires it, we are not the right supplier — and we will say so before you spend time on an RFQ.
No 5-axis
We run 3- and 4-axis machining centres plus sinker EDM. Many “5-axis” parts can be made in two or three setups; if a part genuinely needs simultaneous 5-axis, we have it quoted by a partner shop.
No in-house anodising
Finishing is done by long-term partner plants and quoted as one finished part, one invoice. We do not label partner work as in-house.
No gold or platinum
We machine titanium, stainless, aluminum, brass, copper and engineering plastics. Precious metals are not offered.
How to vet us before you send a drawing
- Ask for the last three first-article reports. We will send redacted PDFs; the measurements and the part numbers stay visible.
- Ask what we do not have. The answer should be immediate: no ISO 9001, no 5-axis, no in-house anodising.
- Ask who owns the quote. The engineer who prices the part should be the one who plans the route.
- Ask for a DDP price. A landed cost is the only number you can compare with a local quote.
- Start with one part. A $200 prototype tells you more than a brochure.

Shipping and Incoterms
Japan: JIS drawings are welcome, we quote and correspond in English, and we ship DDP to Japanese ports and door addresses. See the Japan page → If your drawing uses JIS symbols, send it as-is; we confirm the interpretation in the DFM note.
We ship DHL, FedEx or UPS door to door, or through your forwarder. EXW, FOB Shenzhen/Guangzhou, DAP and DDP are all available. For first orders, DDP is usually the least surprising: the price includes freight, duty and brokerage, so there is no customs invoice after the parts arrive. We declare full value and send tracking on every shipment.
FAQ
Are you ISO 9001 certified?
No. We do not hold ISO 9001, ISO 13485 or IATF 16949. We say this before you send a drawing. If your RFQ requires certification, we are not the right supplier. If it requires a first-article report, material certificates and a named engineer, we are.
How do I know the parts will measure right?
The first article is measured on the CMM before the run continues, and the report is sent as a PDF. In-process checks use gauges; final inspection is on the CMM. You can also nominate a third-party inspection (SGS, Bureau Veritas, TÜV) at your cost.
What about my intellectual property?
NDA on request, no photography without permission, no client names in marketing, and files are visible only to the engineer and programmer on the job. We do not sell your parts or your design.
How do you ship to the US or Europe?
DHL, FedEx or UPS door to door, or your freight forwarder. We quote EXW, FOB Shenzhen/Guangzhou, DAP or DDP. DDP is usually the least surprising for first orders.
What is the real lead time?
Typically 7–15 working days after drawing approval, depending on material, finish and quantity. Prototypes are usually 5–10 working days. The quote states the date; if it slips, we tell you before it slips.
Can I visit the factory?
Yes. Tell us the dates and we will arrange the visit, the machines you want to see and the parts you want to inspect. Video walk-throughs are available if travel is not practical.
Why are you cheaper than a local shop?
Lower labor and overhead, not lower tolerance. The risk is not the price; it is communication, IP and freight. We quote DDP, put everything in writing and keep one engineer on the job to remove those risks.
Send one drawing. Judge us on the part, not the brochure.
Upload a STEP file and drawing. We reply with price, lead time, DDP option and a DFM note within 16 hours.
