Start with the part function
The supplier needs to know whether the part is a cosmetic enclosure, structural bracket, internal chassis, control panel or supplier rescue project. Function tells the reviewer which risks deserve attention.
Separate confirmed details from assumptions
If material, finish or tolerance is not final, say so directly. A useful quote can list assumptions and alternatives instead of hiding uncertainty in a single price.
Use drawings for requirements, not only geometry
A STEP file shows shape, but the PDF drawing should carry tolerances, finish notes, hardware callouts, critical dimensions and inspection needs.
| Input | Why it matters |
|---|---|
| Part type | Frames the likely process route and DFM risks. |
| Material and thickness | Controls laser settings, bend radius, weight, finish and cost. |
| Quantity tiers | Separates prototype, pilot and repeat production assumptions. |
| DXF, STEP and PDF files | Gives both geometry and manufacturing notes. |
| Finish and cosmetic zones | Prevents coating, masking and packing surprises. |
| Critical dimensions | Defines what must be checked before shipment. |
Next step
Use the guide to prepare a cleaner inquiry, then attach the best available files through the RFQ form. If an item is unknown, say so directly so the first reply can separate quote assumptions from confirmed requirements.
