RFQ detail What to share Why it matters
Drawings & revision Current 2D drawing and 3D CAD, part number, drawing revision and units. Identify which file controls conflicting dimensions. Keeps pricing tied to one design.
Operating conditions Continuous and peak temperature; chemical identity, concentration and contact time; load, motion and electrical needs. For wear parts, add mating surface and lubrication. Defines the conditions each candidate material must withstand.
Material & form Exact grade, filler and color if specified; finished part or stock shape. If the grade is open, state required performance and restricted substitutions. Defines the material and supply scope.
Quantity & timing Prototype quantity, first order, repeat demand and required delivery date. List each quantity stage separately. Connects setup and production costs to each order size.
Tolerances & finish Critical dimensions, datums, fits, sealing surfaces and finish requirements. Explain each critical feature's function. Focuses machining effort on assembly performance. Blanket tight tolerances can add unnecessary cost.
Inspection & documents Required dimensional report, material identification, certificate of conformity and traceability records. Include measurement or conditioning requirements. Defines the acceptance basis and documentation scope.
Handling & delivery Protection for critical surfaces, cleanliness, packaging needs and delivery location. Defines delivered-part requirements and the shipping basis.

Buyer questions

Frequently Asked Questions

A drawing or sketch with the current revision, the material and grade if known, the quantity and a target lead time. If the material is open, tell us the operating conditions and we will recommend a grade.

PEEK, PPS, PI, PEI and PAI — as machined parts and fabricated components. Each material page covers typical properties, applications and limitations.

For the specific grade, yes — not a family-level sheet. Send the grade and the test basis you need through the contact form, and we will confirm what is available before you commit.

Certificate of conformance, inspection reports and batch traceability are available on request. List the documents when you send the inquiry so they are included in the quote.

It depends on material availability, part size and quantity. Send the drawing and we will give you a realistic date before you commit.

Start with operating temperature, then check chemicals, load and dimensional stability. Use the material selection tool, compare typical properties, then request the grade datasheet before you finalize the material call. If the answers still conflict, contact engineering support directly.
