Why does the quantity change the price so much?

Because the tooling is a fixed cost divided by it. A $12,000 die over 50 parts is $240 a part; over 5,000 it is $2.40. Nothing else in the cost varies by two orders of magnitude, which is why the quantity is the first thing to establish on any die-cut quote and why two quotes for the same part can differ tenfold without either being wrong.

When should I use a die-less process instead?

Below the crossover, which is roughly where the extra per-part conversion cost of cutting without a die times the volume equals the die cost. Knife cutting and waterjet cost more per part: slower, more machine time, but nothing up front. For a few hundred acoustic parts they usually win comfortably; by a few thousand the die is ahead. Running this page with the tooling at zero and a higher conversion cost gives the comparison directly.

Should tooling be amortised or charged separately?

Commercially either works, and they are not equivalent. Charging the die separately as a one-time line is cleaner, protects you if the volume never materialises, and makes the part price comparable across quantities. Amortising it into the part price is what customers usually prefer and it puts the volume risk on you, if they order 200 against a 2,000 forecast you have absorbed 90% of the die. This page shows the amortised view; the separate-line view is this page with tooling at zero, plus the die as its own quote line.

What is the 10% volume figure for?

It is the volume at which tooling stops being a material part of the price, which makes it a good anchor for a minimum order quantity or a customer conversation. Below it, the quote is meaningfully a tooling quote and the price is sensitive to volume assumptions; above it, the price is stable and the discussion moves to material and conversion where it belongs.

Does die wear matter?

On long runs, yes, and this page does not model it. A steel-rule die cutting abrasive faced material dulls and needs re-ruling, typically after tens of thousands of impressions. Where that will happen inside the quoted volume, add the expected refurbishment to the tooling cost. It is the same kind of one-time charge and belongs in the same line.

Why is material cost per part rather than per sheet?

Because that is the unit the rest of the quote is in, and because it keeps the nesting question in one place. The trim yield page turns sheets into a per-part material cost including the offcut, which is the number to bring here. Doing it the other way round makes the nesting loss invisible at exactly the point where someone is deciding whether the part is competitive.

Acoustic, Noise, Vibration & NVH Products calculator

Acoustic Component Cost and Tooling Amortisation Calculator

Cost a die-cut acoustic component with the tooling where you can see it. Enter the quantity the tooling is amortised over, the material and conversion cost per part, and the one-time die and tooling cost. The calculator returns the fully loaded cost per part, the total for the quantity, what the tooling adds to each part, and the volume at which tooling falls to a tenth of the price. For acoustic trim, gaskets and damping patches the die is frequently the largest single line in the part cost at anything short of production volume, and a quote that does not state its assumed volume is not really a quote.

What this calculator does

Cost a die-cut acoustic component with the tooling amortisation visible, and find the volume at which the die stops dominating the price.
Use it for quoting a die-cut acoustic component at several volumes, deciding between a die and a die-less cutting route for a new part, explaining why a prototype price is ten times the production price, setting a minimum order quantity that keeps tooling a sensible share, building the cost side of a quote before adding freight and margin.
Cost a die-cut acoustic component with the tooling amortisation visible, and find the volume at which the die stops dominating the price.

Formula used

Variable cost per part = material + conversion
Tooling amortised per part = die and tooling cost ÷ quantity
Fully loaded cost per part = variable cost + tooling per part
Total cost for the quantity = fully loaded cost per part × quantity
Tooling share = tooling per part ÷ fully loaded cost × 100
Volume where tooling falls to 10% = 9 × tooling cost ÷ variable cost per part

Inputs explained

Quantity to amortise over: The volume the tooling is being spread across: an order, a release, or an annual forecast. It changes the part price more than anything else on this page.
Material cost per part: Foam, fibre, barrier, facing and adhesive at the sheet consumption the nest actually uses, not the finished part area.
Conversion cost per part: Cutting, assembly, inspection and packing per part. The assembly labor page gives the labor share of this.
Die and tooling cost: One-time cost of the die, fixture and first-article approval. Steel-rule dies for acoustic trim commonly run $2,000–$20,000 depending on size and tolerance.

How to use the result

Best suited to quoting a die-cut acoustic component at several volumes, deciding between a die and a die-less cutting route for a new part, explaining why a prototype price is ten times the production price, setting a minimum order quantity that keeps tooling a sensible share, building the cost side of a quote before adding freight and margin.
Amortises linearly. If tooling is shared across several part numbers or carried across years, the real per-part charge is lower and needs allocating outside this page. Ignores die wear and refurbishment, which on long runs adds a periodic cost this page does not see. Does not model minimum order quantities or setup charges per release, which on small frequent releases can rival the tooling. No learning curve, so a first production run will cost more than shown. Not a price. Margin, freight and installation are on the quote margin page.
