Metal stamping is the one process where the part on the drawing is almost never the expensive thing. The press cycle that punches a bracket out of a coil takes a fraction of a second and costs almost nothing per piece — the money is in the die that makes it possible and the volume you spread that die over. That is exactly why metal stamping cost trips up shops used to quoting machined or fabricated work: you cannot price a stamped part by looking at the part. You have to price the tool, the material strip, and the press time as three separate engines, then divide the tooling across the run. Quote it like a milled part and you will either scare off the customer with a tooling-loaded unit price or quietly eat a die that never gets paid back.

This guide builds a stamping quote from those three engines — tooling, material, and press time — and shows how the per-part number swings with volume, so a 1,000-piece order and a 500,000-piece order get the price each actually deserves instead of the same flat figure.

The three cost engines of a stamped part

A stamped part has three cost blocks that behave completely differently, and the mistake is treating them as one.

• Tooling — the die that forms the part. A one-time (or amortised) cost that does not change with volume, only with how many parts you spread it over.
• Material — the coil or sheet, costed by the strip the part consumes after layout, including the skeleton scrap, not the net part weight.
• Press time — the burdened press rate divided by strokes per minute, often a tiny number per part on a fast progressive die.

Tooling is fixed per program. Material and press time are per part. The whole art of a stamping quote is keeping them apart so you can see what the unit price is really made of at any given volume.

Tooling: the cost that lives outside the part

Die cost is the single biggest variable in a stamping quote and the one customers least expect to pay for up front. A simple single-station blanking die for a flat washer might be a few thousand euros; a multi-station progressive die that blanks, pierces, forms, and cuts off in one strip can run €15,000 to €80,000 or more depending on stations, tolerances, and material. Treat that number as a separate line, quoted once.

The trap is amortisation. If you fold tooling into the unit price, the per-part figure becomes a hostage to the volume assumption — and customers shop on unit price. Look at what a €18,000 die does to the part price at different run sizes:

Annual volume	Die cost	Tooling per part
1,000	€18,000	€18.000
10,000	€18,000	€1.800
50,000	€18,000	€0.360
250,000	€18,000	€0.072
1,000,000	€18,000	€0.018

Same tool, same part — a price that ranges from €18 to under two cents per piece purely on volume. This is why stamping is a volume game: below a few thousand parts the tooling dominates and another process (laser, turret punch, machining) is usually cheaper, and only at scale does the stamped unit price collapse to the figure that wins the long-run contract. Quote tooling separately, state the volume your unit price assumes, and you stop arguing about a number that means nothing without its run size.

Tonnage: sizing the press before you can rate it

You cannot quote press time until you know which press the job runs on, and that comes down to tonnage. The force to blank or pierce a part is its cut perimeter times the material thickness times the shear strength:

1. Measure the total cut perimeter — outer profile plus every pierced hole and slot (mm).
2. Multiply by material thickness (mm).
3. Multiply by the material's shear strength (N/mm², roughly 0.8 × tensile — about 350 for mild steel, 520 for stainless, 180 for soft aluminium).
4. The result is blanking force in newtons; divide by 1,000 for kN, and by ~9.81 for metric tonnes.

A part with a 300 mm cut perimeter in 2 mm mild steel needs 300 × 2 × 350 = 210,000 N ≈ 210 kN ≈ 21 tonnes of blanking force. Add forming, drawing, and a safety margin, and you are sizing a press in the right class. Tonnage decides the machine; the machine decides the burdened hourly rate. A 40-tonne mechanical press does not cost the same per hour as a 400-tonne one, and the machine shop hourly rate calculation applies exactly the same way here — build a burdened rate per press, not a shop-wide blend, or you overprice the small work and underprice the big.

Material: the strip, not the part

Like any flat-stock process, stamping is costed from the material consumed, not the material in the finished part. The driver is the strip layout: how the part nests along the coil, the width of the strip, the pitch between hits, and the skeleton scrap left behind. A part with a 60 mm footprint stamped on a 75 mm strip at an 80 mm pitch consumes a 75 × 80 mm rectangle of coil per hit — and the difference between that and the net part is pure scrap you paid for.

Material cost per part is therefore strip area (or weight) per hit times the coil price per unit, plus a realistic scrap factor — often 25–50% of the coil ends up as skeleton on a single-out layout, less if the layout is tight or multi-out. Good die designers fight for material utilisation precisely because at high volume a few percent of coil scrap dwarfs everything else in the quote. Quote from the strip, recover the scrap value if you sell it back, and the material line tells the truth.

Press time: strokes per minute, divided down

Press time per part is the cheapest-looking line and the easiest to get casually wrong. It is the burdened press rate divided by the production rate in parts per hour:

• A press running 120 strokes per minute on a single-out progressive die makes 7,200 parts an hour.
• At a €90/hour burdened press rate, that is €90 ÷ 7,200 = €0.0125 of press time per part.

That is why high-volume stamping unit prices look almost free on the machine side — the press cost is spread across thousands of parts an hour. But the rate has to be burdened (press depreciation, floor, power, maintenance, operator attention, and the feed/straightener line), and the parts-per-hour has to reflect real uptime, not nameplate speed: coil changes, jam clears, and in-die sensing all cut into it. On short runs the setup to hang the die and run the first-off can dwarf the running time — the same batch-divide logic that governs every quote in our manufacturing quote template.

A worked per-part build-up

Putting the engines together for the same part — €18,000 die, €0.42 material per part, €0.0125 press time per part, plus €0.05 secondary/handling — shows where the unit price actually comes from at each volume:

Annual volume	Tooling/part	Material + press + sec.	Cost/part	Price @ 35% margin
5,000	€3.600	€0.483	€4.083	€6.28
25,000	€0.720	€0.483	€1.203	€1.85
100,000	€0.180	€0.483	€0.663	€1.02
500,000	€0.036	€0.483	€0.519	€0.80

The variable cost barely moves; the whole story is tooling amortisation. (Price uses margin, not markup — price = cost ÷ (1 − margin %); the difference is explained in margin vs markup.) Present a quote like this and the customer sees immediately why committing to volume earns the lower price — and why a 5,000-piece order carries a unit cost six times the half-million run.

Where stamping quotes go wrong

The recurring errors all come from collapsing the three engines into one number:

• Burying tooling in the unit price. The customer compares your tooling-loaded €6 part to a competitor's tool-separate €1 part and you lose, or you win an order whose volume never amortises the die.
• Quoting from net part weight. Ignoring strip scrap understates material by 25–50% on every single piece — invisible on one part, fatal across half a million.
• Nameplate strokes per minute. Quoting at 120 SPM when real uptime delivers 80 silently underprices press time and capacity.
• Wrong process for the volume. Below a few thousand parts the die rarely pays back; a flat-blank job may belong on the laser or in a sheet-metal workflow instead. When the stamped part feeds a welded assembly, the cost flows on into welding and fabrication estimation.

From drawing to stamping quote, the same way every time

The slow, error-prone part of a stamping quote is reading the inputs off the print: material and thickness from the title block, the cut perimeter and hole count that drive tonnage, the bends and forms that decide the die complexity, and the flat-blank size that sets the strip. Under deadline pressure that reading gets shortcut — perimeter estimated, scrap ignored, a form missed — and the tooling class gets guessed.

QuoteBuddy reads the technical drawing and surfaces those inputs — material, thickness, geometry, perimeter, hole and feature count, and the operations the part implies — so the estimator works from a complete picture instead of a hurried scan, the way our AI drawing interpretation approach works across every process. The cost engine then builds the price from your press rates, material costs, tooling estimate, and target margin, keeping tooling, material, and press time as separate lines and showing the unit price at each volume — the same way every time, so two estimators quoting the same part land on the same number.

Start a 30-day trial and run a few real drawings through it — from upload to a complete, itemised quote with the tooling split out and the per-part price laid against volume. See whether the cost it builds matches what you would have quoted by hand, and where a buried die or ignored scrap was quietly costing you.
