A clear RFQ can make a big difference when sourcing custom metal parts. If key information is missing, suppliers may need several rounds of questions before preparing a quote. For buyers, this can also make supplier quotes difficult to compare.
A practical metal parts RFQ should include:
2D drawing and 3D CAD file
Part number and revision
Material and grade
Quantity
Critical dimensions and tolerances
Surface finish
Inspection requirements
Delivery date and shipping location
Material and quantity are especially important because they can affect both the manufacturing process and price. If future orders are expected, an estimated volume can also help suppliers recommend a suitable production method.
Not every dimension needs a tight tolerance. Mark the dimensions that affect assembly or product performance and use standard tolerances where possible. Unnecessary precision can increase machining and inspection requirements.
The manufacturing process also matters. Depending on the part, production may involve stamping, CNC machining, laser cutting, bending, welding, injection molding, or die casting. Some parts may also require dedicated tooling or molds.
The lowest price is not always the best option. Before making a buyer decision, check whether suppliers are quoting the same material, quantity, finish, inspection, packaging, and delivery requirements.
Ask suppliers to identify any assumptions, exclusions, and lead-time conditions. This makes different quotes easier to compare and reduces unexpected costs later.
