What to specify in your RFQ

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

  • Part dimensions and tolerances

    Provide exact part dimensions, critical tolerances, and any geometric features that affect mold complexity (thin walls, living hinges, threads).

  • Material (resin) and grade

    Specify the polymer type, grade, color, and any additive requirements (UV resistance, flame retardant, FDA compliance).

  • Annual and per-run quantities

    State target piece counts per production run and yearly volume to determine tooling type, cavity count, and cost amortization.

  • Tooling requirements and lifespan

    Indicate expected mold life (shots), preferred steel grade, surface finish, and whether prototypes or soft tooling are acceptable.

  • Functional and regulatory standards

    List applicable industry standards, certifications (e.g., RoHS, REACH, FDA), and any mechanical or electrical performance requirements.

  • Lead time and milestones

    State required dates for prototype, first article inspection (FAI), and full production so manufacturers can confirm capacity.

  • Packaging and secondary operations

    Note post-molding processes required (assembly, painting, ultrasonic welding, printing) and packaging/unitization needs.

Sourcing FAQ

How do I verify a China injection molding manufacturer?
Ask for factory photos, tooling shop evidence, a company business license, references or past part examples, and request an in-person or third-party audit if critical. Suppliers that explicitly state they are a mold maker and show tooling capacity are stronger candidates.
What drives lead time for injection-molded parts?
Tooling design and build time is the main driver—complex multi-cavity or high-precision molds take longer. Material availability, required secondary operations, and current factory workload also affect lead time.
What minimum order quantities (MOQs) should I expect?
MOQs vary by supplier and by whether you use prototype/soft tooling or production molds; low-volume proto runs can start from dozens to hundreds, while production tooling is commonly justified at thousands per year. Ask each supplier for their MOQ by tooling type and part complexity.
Which certifications should I request?
Request quality system evidence such as ISO 9001 and any industry-specific approvals (e.g., ISO/TS for automotive, FDA for food/medical contact). Ask suppliers to show test reports and material certificates for critical applications.
