Define the part purpose
Explain whether the part is for design review, fit validation, a functional test, replacement, or repeat production. Identify mating surfaces and the features that control assembly. A clear purpose helps set realistic material and inspection requirements.
Specify the plastic grade
Name the exact resin grade and condition when required by the design. If the grade is open, state which properties matter and how an alternative will be approved. Do not assume different commercial or generic names are interchangeable.
Prepare the model and drawing
Provide matching files with units, part number, revision, quantity, datums, critical dimensions, threads, and any inserts. State the finish, color, transparency, or other appearance requirement where it affects acceptance.
Compare machining and molding purpose
Clarify whether the prototype needs to match the geometry, material, or process of a later molded part. A machined sample does not automatically reproduce the behavior of a molded part; confirm the method is suitable for the test being performed.
Agree on inspection and quote scope
List acceptance criteria, requested measurements, records, packaging, and delivery assumptions. Ask the supplier to confirm what finishing or secondary operations are included and to identify exclusions.
