BUYER GUIDE
What Should Be on a Metal Stamping RFQ Checklist?
Published by Beizhou Metal · General buyer guide
A stamping RFQ needs enough information to evaluate both the part and its tooling or process assumptions. No supplier can confirm feasibility, tooling cost, or production timing from a generic checklist alone.
Part and revision
Provide the current 2D drawing and 3D model when available, material grade and thickness, finish, critical dimensions, and application constraints. Identify the governing revision and open design questions.
Demand profile
State prototype or tryout quantity, initial order quantity, expected annual demand, forecast horizon, release pattern, and required packaging. Label forecast quantities as planning estimates, not purchase commitments.
Tooling scope and ownership
Ask what tooling concept and scope are included, who pays for design and tryout, who owns the tooling, where it will be stored, how maintenance and modifications are handled, and how tooling can be transferred.
Material and process review
Clarify exact material specification, condition, any approved substitution path, and the proposed process route. The selected supplier must confirm feasibility for the drawing; no thickness, press capacity, or tolerance limit is implied here.
Acceptance and records
Define sample approval, critical dimensions, inspection methods, traceability, material documents, finish criteria, nonconformance handling, and change notification. Request only records that support the contract and risk.
Commercial and delivery assumptions
Separate tooling, tryout, recurring unit price, inspection, finishing, packaging, freight, and lead-time assumptions. Compare bids using the same quality and delivery scope.
A practical buyer worksheet
| Material description | Information to confirm | Avoid assuming |
|---|---|---|
| Aluminium / aluminum | Specified alloy, temper, thickness and finish | Do not treat a generic aluminium name as a full specification. |
| Cold-rolled steel sheet | Grade, condition, thickness and required surface | Do not treat a commercial material nickname as a complete grade. |
| Hot-rolled steel plate | Grade, thickness, condition and intended stamping operation | Stamping hot-rolled plate does not mean hot forming. Hot-rolled describes the material condition, not the forming process. |
| High-strength steel sheet | Specified grade and condition, drawing and acceptance requirements | Do not assume all high-strength grades use the same forming route. |
This is a scope checklist, not a supplier capability or engineering approval. Discuss metal stamping, or contact us with a non-confidential outline.
Review note: This buyer guide is a general planning aid. Confirm project-specific engineering, supplier capabilities, commercial terms, and legal requirements before relying on them.
