Key takeaways
- Send a dimensioned 2D drawing; add a STEP model if there is machining.
- State alloy and temper — or the loads and finish if you want a recommendation.
- Annual volume and batch size change the price more than almost anything else.
- Identify cosmetic faces and critical dimensions explicitly.
- Ask for die cost, unit price, sample lead time and production lead time separately.
An incomplete request for quotation (RFQ) produces vague quotes, rounds of questions and quotes you cannot compare. A complete one gets you a fast, accurate, itemised answer. Use this checklist.
The RFQ checklist
| Item | Why it matters |
|---|---|
| 2D drawing (PDF + DWG/DXF) | Defines the section, weight per metre and die design |
| 3D model (STEP) | Needed for machining, cut-outs and assembly features |
| Alloy and temper | Sets strength, finish quality, press speed and price |
| Tolerance standard | EN 755-9, EN 12020-2, ANSI H35.2 — plus critical dimensions |
| Cut length and length tolerance | Affects yield, sawing method and packaging |
| Annual volume and batch size | Drives price, die strategy and scheduling |
| Surface finish | Class, color, gloss, cosmetic faces, masked areas |
| Machining and assembly | Holes, threads, pockets, inserts, sub-assembly |
| Packaging | Film, interleaving, crates, labels, container plan |
| Delivery terms | Destination, Incoterms, target dates |
| Documents | Mill certificates, inspection reports, certificate of origin |
Tips for a better quote
- Mark critical dimensions rather than tightening every tolerance.
- Identify visible faces so surface quality is controlled where it matters.
- Share the function. A sentence about what the part does helps engineers suggest cheaper alternatives.
- Say if you are flexible on alloy, finish or design — you may save money.
- Give realistic volumes. Overstated forecasts lead to the wrong die strategy.
What a good quote should show
Ask for these items separately so quotes are comparable:
- Die cost (one-time) and die ownership terms.
- Unit price — per kg or per piece — and the weight per metre it is based on.
- Machining, finishing and packaging costs.
- Minimum order quantity per run.
- Sample lead time and production lead time.
- Payment and delivery terms.
Common mistakes
- Sending only a 3D model with no tolerances.
- Omitting annual volume, so price breaks cannot be offered.
- Specifying finishes without a class or color reference.
- Forgetting packaging — then receiving scratched parts.

Frequently asked questions
Can I get a quote without a drawing?
A budget estimate is possible from a sketch or sample with key dimensions, but a firm quote needs a dimensioned drawing so the die, weight and tolerances can be calculated.
Which file formats are best?
PDF for the dimensioned 2D drawing, DWG or DXF for the cross-section, and STEP for 3D models. Neutral formats avoid version problems.
Should I sign an NDA before sending drawings?
If your design is sensitive, yes — ask for a non-disclosure agreement before sending files. Reputable suppliers treat drawings as confidential either way.
