The difference between a weak enquiry and a strong one is usually not the part. It is whether the factory can separate “nice to know” from “must be true.” A buyer who marks critical features, visible surfaces, material and quantity can usually get a more meaningful quote faster.
Score your RFQ before sending it
Use this rough 100-point self-check. The goal is not to impress anyone. It is to make the first engineering review faster.
| Item | Weight | Why it matters |
|---|---|---|
| Drawing, sketch or 3D file | 20 | Allows process split, tooling and inspection review |
| Material confirmation | 10 | Stainless, brass, titanium, copper or iron changes tooling and cost |
| Quantity split | 10 | Prototype and production use different setup and inspection logic |
| Finish by area | 10 | Polish, PVD, brushing, plating and etching are not interchangeable |
| Critical dimensions | 20 | The buyer must say which features control fit or performance |
| Target date | 10 | Some drawings need an earlier sample checkpoint |
| Destination and role | 10 | Helps confirm receiving inspection, packaging and compliance scope |
| Application boundary | 10 | Liquid, pressure, food, medical or safety use changes review |
What to send
- STEP, STP, PDF or DWG drawing
- Material specification and any material certification expectation
- Prototype quantity and production quantity
- Finish by area, color, PVD, plating or etching notes
- Critical tolerances, not just the global tolerance
- Target date, destination and receiving inspection requirement
- Any leakage, pressure, food, medical or safety boundary
What a useful reply should include
The buyer should expect: manufacturability notes, suggested process split, finish recommendation, quantity-based price logic, sample expectation and one clear next action. If the reply only says “send more details,” the RFQ was usually too open.
