What to specify in your RFQ

Manufacturers quote faster and more accurately when your request covers these points.

  • Part dimensions and tolerances

    Provide finished part size, wall thickness, critical dimensions and required tolerances so the moulder can confirm machine capability and mold design complexity.

  • Material specification

    Specify polymer type, grade, color, filler or flame-retardant requirements and any food/medical-grade or high-temperature needs.

  • Mold requirements

    State whether you need the supplier to supply or manufacture the mold, expected cavity count, material (steel/Al), and expected lifetime/cycles.

  • Surface finish and secondary operations

    Declare required surface texture, painting, printing, ultrasonic welding, overmoulding or assembly operations the supplier must perform.

  • Quantity and ramp profile

    Give target annual and per-run quantities, expected future volume growth, and desired batch sizes so suppliers can quote tooling amortization and per-piece pricing.

  • Mechanical / regulatory standards

    List applicable standards (e.g., automotive OEM specs, RoHS, REACH, ISO 9001, IATF 16949, medical certifications) the parts must meet.

  • Lead time and logistics

    State desired prototype, sample and production lead-times, packaging, and delivery terms (EXW, DAP, DDP) to align supplier capacity and transport planning.

Sourcing FAQ

How do I verify an injection moulding supplier in Poland?
Ask for proof of in-house moldmaking and machine list (clamping forces), visit their plant or request recent customer references, and review quality certifications that match your industry.
What minimum order quantities (MOQs) should I expect?
MOQs vary: prototyping and small-series runs are common for companies with small machines, while mass-production suppliers amortize tooling and expect larger runs—specify quantities when requesting quotes to get accurate offers.
Which certifications matter for Polish injection moulders?
Commonly requested certifications include ISO 9001 and IATF 16949 for automotive; for medical or food applications, ask for ISO 13485 or relevant material traceability and hygienic processing evidence.
What drives lead time for injection-moulded parts?
Lead time is driven by mold design and manufacture, tooling lead-time, machine availability, required secondary operations, and material lead times; clarify prototype vs production schedules upfront.
