How to Prepare an RFQ for Custom Industrial Components
A clear RFQ helps suppliers select a realistic process, identify technical risk and quote the correct production quantity.
1. Identify the component and application
Provide the part name, equipment or assembly, function, mating interfaces and whether the requirement supports new production, automation, maintenance or replacement.
2. Send the best technical reference available
A 2D drawing and 3D model are ideal. A physical sample, damaged part, marked photographs or dimensions can also start the review when original drawings are unavailable.
3. Separate critical requirements from preferences
Identify functional dimensions, datums, fits, surface finish, heat treatment, coating and inspection items. Avoid applying tight tolerances to every feature without a functional reason.
4. State material and working conditions
Provide the specified grade when known. Otherwise describe load, wear, impact, chemicals, temperature, moisture, speed and contact materials so feasible options can be compared.
5. Give realistic quantity information
Include prototype or first-article quantity, initial production quantity, estimated annual demand, expected order frequency and number of machines or sets. This is especially important for tooling- or setup-intensive parts.
6. Define inspection and delivery expectations
State required reports, material documents, critical measurements, packaging, target delivery and any applicable standard before quotation.
RFQ checklist
Part or application; drawing, model or sample; revision; material; initial and annual quantity; critical dimensions; working condition; inspection; finish; target delivery; and contact details for technical questions.
