Procurement teams searching for an injection molding quote China suppliers often receive three incompatible numbers for the same STEP file. The gap is rarely dishonesty — it is missing RFQ detail. Suppliers fill blanks with assumptions about steel, cavitation, inspection, and Incoterms.
This guide shows what to attach so quotes compare apples-to-apples and shortlist partners who can actually deliver — not just win on the lowest line item.
Minimum package before you ask for quote
- STEP or native CAD with revision block
- 2D PDF with CTQ dimensions and cosmetic class (A/B/C)
- Material grade or performance spec (not just “ABS”)
- Year-one and steady-state annual volume
- Target SOP date and ramp curve if known
- Ship-to region and preferred Incoterm (FOB vs DDP)
Use our full RFQ checklist as a template.
What a credible quote should break out
| Line item | Why it matters for TCO |
|---|---|
| Tooling: steel, cavitation, hot/cold runner | Explains price spread between suppliers |
| Included T1 iterations | Avoids change-order surprises |
| Piece price at stated volume bands | Validates amortization math |
| Tooling ownership / deposit terms | Exit risk if relationship ends |
| Lead time to T0 / T1 | Launch planning |
Red flags in a “too cheap” injection molding quote
- No DFM comments on your geometry
- Tooling lump sum with no steel spec
- Verbal “we can hit any tolerance”
- No mention of inspection or FAI scope
Compare landed cost with our TCO guide — not FOB alone.
How Deuchi responds to quote requests
We return a written DFM summary with quote when geometry allows — flagging wall, gate, and tolerance risks before you cut steel. Programs cover contract manufacturing from mold build through secondary ops.
FAQ
How fast should I expect a first quote?
Complete RFQs often receive initial feedback within 1–3 business days; complex multi-cavity tools need longer engineering review.
Should I get multiple injection molding quotes from China?
Yes — two or three, with identical attachments. Score DFM depth, not price alone.
Can I get a budgetary quote before design freeze?
Yes, label it preliminary and re-quote after DFM sign-off at ~80% CAD freeze.
