Seed Q&A: 24 questions, 24 URLs
Answers are public. Sign in only to ask or to order. Twenty-four seeds from real RFQ topics, six per group — not an empty forum.
Quote & order
Can you make quantity 1?
Yes. Prototyping starts at 1 pc, confirmed by process — no volume floor.
How fast is the AI Instant Quote?
The reference quote is near-instant. Engineering review targets 12 business hours (Dongguan UTC+8).
Is the AI quote a locked final price?
No. It is an itemized reference. Complex parts are confirmed by engineering.
Do I need an account to see the AI quote?
No. Preview the itemized reference with no account. Sign in only to save or order.
Are duties included? Do you ship worldwide?
Duties and import VAT are usually excluded; Incoterms in writing. We ship worldwide.
Which CAD formats do you accept?
STEP/STP preferred; also STL, IGES, SolidWorks, Parasolid, DXF/DWG, PDF. ≤80 MB.
Process & tolerance
When do 0.001 mm / ±0.002 mm actually apply?
They are fine-machining targets. Acceptance follows the drawing.
What is the minimum wall thickness on aluminum?
Typical guideline ≥1.0 mm; thinner needs DFM.
When is 5-axis actually required?
When compound angles or mating faces would stack tolerance. Quoted per part, not defaulted.
Do you machine medical implants?
No implants and no device-certification programs. Medical-adjacent structures can be quoted; QA docs optional.
Who confirms threads and thin walls?
The drawing first. Out-of-guideline features go to engineering DFM.
What if the part is larger than the milling envelope?
Typical envelope about 600 × 400 × 250 mm. Larger sizes go to engineering.
Quality & NDA
Can you sign an NDA?
Yes. Ask via the form or live chat before sending sensitive files.
When do I get a dimensional report?
When selected on the quote — not by default. It can ship with the order.
How do I tick QA docs: dimensional report / CoC / FAI / CMM?
All four are optional. Nothing is bundled. No invented ISO numbers.
What does a material certificate actually cover?
CoC / heat-lot traceability per order, within the agreed scope.
Why don’t pages list ISO certificate numbers?
Unverified cert numbers are not marketing. Quality is optional dims / FAI / CMM.
How is CAD handled before an NDA is signed?
Uploads are confidential over HTTPS with an allowlist. A formal NDA can still be signed.
Lead time & factory
Do lead times include international shipping?
Reference totals include production plus sketched freight, shown separately.
What is inside the Express ~6-day sketch?
About 3 production days + 3 freight days. Finishes are not assumed in the shortest production days.
What do I see on a factory visit?
Campus, machine shop, multi-axis/VMC stations, and QC. Street address after verification.
How is the 12-hour engineering reply counted across time zones?
On Dongguan business days, UTC+8, target within 12 hours.
When does the lead-time clock start?
Usually after order confirmation and material/process readiness.
Why isn’t the factory street address on the page?
We publish Dongguan, Guangdong, China. Street-level address after verification.
