What to specify in your RFQ

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

  • Molding process

    Specify compression, transfer, injection, liquid injection or dip molding so the supplier can confirm equipment and tooling fit.

  • Material / compound

    List the elastomer (e.g., silicone, NBR, EPDM, neoprene) and any required hardness, color or chemical resistance.

  • Part drawings and critical dimensions

    Provide detailed drawings with tolerances, cross-sections and critical functional dimensions for tooling and quality planning.

  • Secondary operations

    State if you need rubber-to-metal bonding, machining, assembly, or post-curing so the supplier can confirm capabilities.

  • Volume and stages

    Give expected annual quantity, typical batch size and whether you need prototype, low-volume or high-volume production.

  • Tooling expectations

    Specify who owns tooling, expected tool life, and lead-time targets; include preferred tool materials or maintenance requirements.

  • Quality and certifications

    List required quality standards or certifications (e.g., ISO 9001, IATF, RoHS, specific material certifications) upfront.

Sourcing FAQ

How do I verify a rubber molder's capability?
Request examples of similar parts, details on molding processes and press sizes, tooling photos or references, and any relevant quality certifications.
What drives lead time for molded rubber parts?
Tooling design and manufacture, material lead times, required curing/post-processing, and current shop load all affect lead time; prototypes typically take less time than production tooling.
What minimum order quantities (MOQs) should I expect?
MOQs vary by process and supplier: prototype runs can be single-digit parts, while production runs and amortized tool costs commonly push MOQ higher — ask suppliers for quantity break pricing.
Which certifications matter for sourcing rubber molded parts?
Commonly requested items are ISO 9001 for quality management, material-specific certifications (e.g., biocompatibility for medical silicones) and customer-specific approvals; request documentary evidence.
