Stamped Parts: A Buyer's Guide from Drawing to Production

This guide is for engineers and purchasers sourcing a new stamped part that needs new tooling. It walks through the decisions in the order they usually arise, from the first drawing review to the first shipment. Each section summarizes one step and links to a detailed article. Read it before you send an RFQ, so you know which information will shape the quote.

What will an engineer question on my drawing?

Before any tooling is discussed, a stamping engineer checks the material callout, bend radii, hole sizes and edge distances, and tolerances, roughly in that order. The resulting design-for-manufacturability (DFM) feedback is not a rejection. It lists features that cannot be stamped as drawn, features that cost more than a small change would, and tolerances that look like CAD defaults. Feedback at this stage is far cheaper to act on than a problem found at die tryout. How a stamping engineer reads your part drawing

Should I start with soft tooling or hard tooling?

Soft (prototype) tooling costs less and is built faster, but it is designed for a limited number of cycles. Hard tooling uses hardened tool steel and runs far longer, at a higher upfront cost. Volume matters, but so does design maturity: a part still in customer approval or fit validation is usually a soft-tooling candidate. Skipping soft tooling is reasonable when the design is proven and volume is confirmed. Soft tooling vs hard tooling for stamped parts

How is the production die designed?

Progressive die design follows a sequence: part analysis, strip layout, station sequencing, die set and structural design, then simulation and tryout. The strip layout sets material utilization, which is often the biggest lever on per-piece material cost. Fixing material and major geometry early avoids costly die rework later. How a progressive die is designed

Why does the per-piece price depend on volume?

Unit price equals the variable cost per piece (material, cycle time, secondary operations) plus tooling cost divided by order quantity. This is why a quote without a stated volume is not meaningful. Tooling is amortized against the total committed quantity, so splitting deliveries into scheduled releases changes cash flow, not the unit-price math. A volume range with tiered pricing is a normal request. Tooling amortization and unit price

What must be checked before production is released?

A First Article Inspection (FAI) documents the first parts from a new or modified die against the drawing. A thorough report covers a full dimensional report, material certification, process documentation, cosmetic results, functional tests where applicable, and any non-conformances with corrective action. It does not replace ongoing production inspection. State in the RFQ whether an FAI is required and in what format. First article inspection for stamped parts

How long will it take from RFQ to first shipment?

The stages run in sequence: quoting, tooling design and build, tryout and first article inspection, first article approval, production, QC and packaging, and shipping. On a new part, tooling and tryout usually take the largest share of the time, often more than the production run itself. A complete RFQ and a quick first article review are the most effective ways to shorten the timeline. Repeat orders on qualified tooling skip the tooling stages.

Where to start

Send your part drawing (a 3D model helps), material and thickness, tolerances, expected annual volume or a range, and whether you need an FAI report through our RFQ form. Mention any target ship date and whether the design is still changing. We return DFM feedback and a stage-by-stage timeline, coordinated with our tooling partners before any die design starts.
