How to Prepare a Die Casting RFQ

Send the most complete controlled file set available. A 3D model supports geometry and tooling review, while a 2D drawing defines dimensions, tolerances, finish and inspection requirements.

If the project is confidential, an NDA can be reviewed before files are exchanged. File names and revisions should be clear so the supplier quotes the correct version.

• STEP, STP, IGS or X_T for 3D
• DWG, DXF or PDF for 2D definition
• ZIP for multi-file packages
• State the drawing revision clearly

The quotation depends on annual volume, order pattern and delivery target as much as on the part geometry. Provide the expected annual quantity, the first order quantity and any seasonality.

Also state the target market and any packaging, labelling or logistics requirement, because these affect cost and production planning.

• Annual quantity and first order
• Delivery target and schedule
• Packaging and labelling needs
• Target market and destination

List the inspection documents required for the project, such as dimensional reports, material records, first-article documents or PPAP files. These should be agreed before the quotation is finalized.

State critical dimensions, sealing or functional tests, and any traceability requirement. This lets the supplier quote the inspection effort accurately rather than estimating it later.

• Dimensional and material records
• First-article or PPAP requirements
• Leak, sealing or functional tests
• Traceability and certification needs

A useful response explains what is feasible, what needs to change and what remains uncertain. It should state the tooling and process assumptions behind the price.

It should also list the missing information needed for an accurate quotation. If the response only contains a price without engineering comments, the project risk has not really been reviewed.

• Feasibility and risk comments
• Tooling and process assumptions
• List of missing inputs
• Clear next step and sample plan
