Function
What contacts, locates, slides, insulates or carries load?
Control material identity, machining risk and delivery documentation before deposit.
The same-looking part can need a different material, tolerance or inspection plan depending on load, wear, temperature, product contact and mounting.
What contacts, locates, slides, insulates or carries load?
Which dimension or surface causes downtime when it drifts?
What record lets your team approve the part and repeat the order?
This is where a cheap quote often becomes an expensive production problem.
| Variable | Hidden failure | Required input |
|---|---|---|
| Grade | PEEK or PPS is a family, not one specification | Name resin grade, filler and approved source |
| Cost | Material price magnifies scrap and revision risk | Freeze geometry before production stock is cut |
| Stability | Heat and machining history affect measurement | Agree conditioning and inspection method |
A quotation is comparable only when every supplier is pricing the same material, revision, evidence and delivery boundary.
A sample or measured-photo set can start the feasibility review, but the quotation must state which dimensions, interfaces and assumptions control production. A controlled drawing is preferred for repeat supply.
Tolerance is reviewed by material, geometry, size, wall section, datum scheme and measurement condition. Critical functional dimensions are separated from general features in the quotation and inspection scope.
Provide the destination city or postcode, required date, quantity breaks and preferred Incoterm. DAP vs local-delivered comparison; SST/import handling clarified before deposit.
State your preferred currency and delivery term in the RFQ. DAP vs local-delivered comparison; SST/import handling clarified before deposit.
