Three questions to start
These are complete, practical field guides—not placeholder cards. Use them to prepare a clearer brief, compare material routes and evaluate production evidence before tooling begins.
Resin selection
Move from temperature, load, exposure and finish to an exact thermoplastic grade that can be molded and verified.
Read the material guide
Supplier evaluation
Verify capability fit, tooling ownership, quality release, change control and repeat-supply discipline.

Four useful RFQ inputs
A drawing is the starting point. Function, operating environment, expected volume and approval requirements give the team the context needed to assess process, material and tooling direction.

Align the part, tool and verification plan before production
A credible quotation should make assumptions visible: what is confirmed, what still needs validation and what evidence will be required for first-off approval.
