Mold DFM and RFQ Checklist for Precision Parts
A sourcing checklist for mold design and manufacturing RFQs, covering part drawings, material, tolerances, surface finish, mold life, trial samples and approval evidence.
Quick assessment
Mold RFQs often fail when buyers send only a 3D model or product photo. A usable DFM and tooling quotation needs drawings, material, tolerance, surface finish, annual volume, mold-life target and sample approval rules.
Use this checklist before requesting tooling review for die-cast, plastic, stamped, CNC-assisted or assembled precision parts.
RFQ decision factors
- 2D drawings and 3D files should be reviewed together, not separately.
- Critical dimensions must be marked before the supplier designs inserts, gates, sliders or inspection fixtures.
- Material, shrinkage, plating, heat treatment and assembly forces can change tool design.
- Mold-life, cavity count and expected annual volume affect steel selection and cost.
- Trial sample approval should define dimensions, appearance, function and packaging evidence.
DFM and RFQ matrix
| Review area | Recommended action | Validation evidence |
|---|---|---|
| Drawings and files | Provide 2D drawing, 3D data, revision and critical dimensions. | Controlled revision, tolerance table and marked CTQ dimensions. |
| Material and process | Confirm material grade, surface treatment, heat treatment and assembly environment. | Material specification, finish requirement and process boundary. |
| Tooling structure | Review parting line, gate, slider, ejector, insert and venting assumptions. | DFM notes, mold-flow or tooling review record. |
| Inspection plan | Define sample size, key dimensions, gauge method and appearance criteria. | FAI report, CMM record, photos and defect limits. |
| Commercial basis | Confirm mold ownership, mold life, maintenance, spare inserts, sample quantity and launch schedule. | Quotation terms, acceptance standard and timeline. |
Verification workflow
- Review drawings and 3D data for consistency before quoting.
- Mark critical dimensions, assembly interfaces and appearance surfaces.
- Confirm material, finish, tolerance, expected volume and mold-life target.
- Ask for DFM notes on parting line, gates, sliders, ejectors, inserts and inspection method.
- Approve trial samples with dimensional, appearance, functional and packaging evidence.
- Record revision, acceptance criteria and change-control rules before launch.
Common RFQ risks
A low mold quotation can become expensive if the quote excludes DFM work, insert complexity, inspection fixtures, trial corrections, surface-finish risk or sample approval evidence. Buyers should compare mold quotations by engineering scope, not only by tool price.
Information needed before review
- 2D drawing and 3D file with revision.
- Material, surface finish and heat-treatment requirements.
- Critical dimensions, tolerance and inspection method.
- Expected annual volume, batch size and mold-life target.
- Sample approval standard, packaging need and launch date.
Engineering conclusion
A useful mold RFQ is an engineering package, not a price request. The more clearly buyers define DFM inputs and approval evidence, the faster a supplier can quote a realistic tooling route.
