What we do for Japanese buyers
Prototypes and trial parts
One part or 1–50 pieces, typically 5–10 working days after drawing approval. Use the trial to check the fit, the finish and the reply time before a production order.
Low-volume production
50–10,000 pieces with the prototype fixture and program carried into the batch. No re-quoting the setup, no drift between sample and production.
JIS drawing review
Send the drawing as-is. We confirm ambiguous JIS symbols, surface finish callouts and tolerance class in the DFM note before cutting.
DDP delivery
Door-to-door DDP to Japanese addresses, or FOB Shenzhen/Yantian if you use your own forwarder. Air express is typically 3–6 business days.
English communication
One engineer owns the quote and the DFM note. We reply in English within 16 hours; no handoff to a sales desk.
NDA and confidentiality
Yours or ours. Files are visible only to the engineer and programmer on the job; no photography, no client names, no finished parts under our brand.
JIS drawings and tolerances
Japanese drawings often use JIS symbols, a general tolerance block and a surface finish table. We work from the drawing you already have: send the PDF or DWG with the STEP file, and we confirm the interpretation in the DFM note. Defaults are ISO 2768-mK for unmarked dimensions, ISO 286 IT6–IT8 for fits, and ±0.002 mm on critical milled features. If a JIS callout needs a different route, we say so before quoting.
| Item | What we confirm |
|---|---|
| JIS symbols | Interpretation confirmed in the DFM note |
| General tolerance | ISO 2768-mK default; JIS class on request |
| Fits | ISO 286 IT6–IT8; pin gauge or CMM |
| Surface finish | Ra/Rz converted and confirmed |
| Material | JIS grade or equivalent, with certificate |
If your drawing uses a company standard instead of JIS, send the standard with the drawing.
Shipping to Japan
| Method | Typical transit | Notes |
|---|---|---|
| DHL / FedEx / UPS | 3–6 business days | Door to door, tracking, DDP available |
| Sea freight | 12–20 days | Tokyo/Yokohama, Osaka/Kobe; better for larger batches |
| Your forwarder | FOB Shenzhen/Yantian | We deliver to the port and handle export documents |
Transit times are after dispatch, not after drawing approval. The quote states both dates.
What we do not claim
No ISO 9001
We do not hold ISO 9001, ISO 13485 or IATF 16949. If your customer requires a certificate, we are not the right supplier — and we 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 through long-term partner plants, quoted as one finished part, one invoice. We do not label partner work as in-house.
No Japanese-speaking staff
We correspond in English. JIS drawings are welcome; if a note needs translation, we confirm it in writing before cutting.
FAQ
Do you work from JIS drawings?
Yes. Send the drawing as-is; JIS symbols and Japanese-language notes are fine. We quote and correspond in English, and we confirm any ambiguous callout in the DFM note before cutting.
How do you ship to Japan?
DHL, FedEx or UPS door to door, usually 3–6 business days after dispatch. Sea freight to Tokyo/Yokohama is typically 12–20 days. We quote EXW, FOB Shenzhen/Yantian, DAP or DDP.
Do you have ISO 9001?
No. We do not hold ISO 9001, ISO 13485 or IATF 16949. 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.
Can you handle Japanese tolerances and surface finish callouts?
Yes. We work to ISO 2768-mK by default, ISO 286 IT6–IT8 fits, and ±0.002 mm on critical milled features. JIS surface finish callouts are converted and confirmed in the DFM note.
What is the minimum order?
None. One part is a valid order. Most first orders from Japan are 1–50 pieces, then a production run.
How fast is a quote?
Within 16 hours, usually the same working day. Send a STEP file and a 2D drawing before noon China time; the reply lands the next working day at the latest.
Can you sign an NDA?
Yes, yours or ours. Files are seen only by the engineer who quotes them and the programmer who runs them. We do not photograph or publish client work.
Send one drawing. Judge us on the part.
Upload a STEP file and JIS drawing. We reply with price, lead time, DDP option and a DFM note within 16 hours.
