## Short answer

How forge shops price die cost into quotes: amortize over committed quantity, build in rework and resink, and decide when the customer owns the tooling.

**Intro:** Forging die cost amortization means spreading the cost of designing and sinking the dies, plus expected rework and replacement, across the pieces you expect to forge, or charging it up front as separate tooling. The right method depends on committed quantity, die life, and who owns the tooling. Many forge shops lose money not on the first order but on the third, when dies need resinking and the original quote assumed they would last forever. This guide covers how to structure the die line in a quote and how to track real die life.

**Sections:**

#### What Goes Into Die Cost

**Body:** Die cost is more than the die blocks. It includes engineering and die design, the steel for the die blocks and inserts, rough and finish machining, EDM where cavities need it, heat treatment of the die steel, polishing, trim tooling, and tryout pieces forged to prove the dies fill and meet dimensions. Add the cost of the tryout material, press time during tryout, and any first-article inspection. If the part has a complicated parting line or deep ribs, the die machining and tryout often cost more than expected. Complexity also shortens life, because deep, narrow cavities wear and crack sooner than shallow ones.

**Bullets:**

- Die design and engineering time
- Die blocks, inserts and trim tooling
- Machining, EDM, heat treatment and polishing of the dies
- Tryout material, press time and first-article inspection

#### Amortize or Charge Up Front

**Body:** There are three common structures. The customer pays the tooling charge up front and owns the dies, which removes risk from the forge shop. The shop owns the dies and amortizes cost into piece price over a committed quantity. Or the cost is split, with a partial tooling charge and the rest in piece price. Amortizing is attractive for the customer but moves risk to you: if the program is cancelled after the first lot, the unrecovered balance is yours unless the quote contains a cancellation or minimum-quantity clause. For prototype and low-volume work, charge tooling up front. For long-term agreements, amortize but write protection into the terms.

**Bullets:**

- Customer-owned tooling with an up-front charge
- Shop-owned dies amortized into the piece price
- Split structure with minimum quantities and cancellation recovery

#### Die Life, Rework and Resink Allowance

**Body:** Die life is measured in good pieces per die set, and it varies with alloy, forging temperature, lubricant, press type and how disciplined the shop is with die preheat and cooling. Titanium and nickel alloys, which forge in narrow temperature windows, usually wear dies faster than carbon steel. Include an allowance for die polishing, weld repair and a resink or replacement at the expected end of life. If a die set is expected to last 10,000 pieces and the customer wants 50,000, the quote has to carry at least four additional sets or repairs. Record actual pieces per die set on every job so the next quote uses measured life rather than the estimator's hope.

**Bullets:**

- Pieces per die set by alloy and part family
- Polish and repair cycles between resinks
- Replacement cost at end of life, not only the first set

#### Tracking Die Life in Your ERP or Spreadsheet

**Body:** Most ERPs do not natively track forging die life well. Tools and fixtures modules can store a die as an asset with a life counter, but many shops keep die logs in spreadsheets or paper travelers. The gap matters because die cost per piece is both a quoting input and a margin driver. Capture the pieces forged against each die set at job close, the number of repairs, and the reason for retirement. With that history in place, a read-only AI assistant can answer questions like which part families wear dies fastest or which jobs ran past their quoted die life, with the underlying records cited.

#### When Amortization Math Is Overkill

**Body:** If your work is mostly open-die or standard shapes where tooling is generic, there may be no part-specific die to amortize at all. Likewise, when customers always own tooling and pay for it directly, the quote only needs a clean tooling line. Detailed amortization models are worth building when you carry your own dies, run long-term agreements, and have enough job history to measure die life by family. Otherwise a conservative tooling charge and a documented policy for resinks may be enough.

**Cta:** If your die history lives in spreadsheets and travelers, Netray can help index it so past die life and rework are available when you quote.

**Faq:**

#### How do forge shops charge for dies?

**Answer:** Commonly as a separate up-front tooling charge when the customer owns the dies, or amortized into the piece price when the shop owns them. Quotes for amortized tooling should specify the committed quantity and what happens to unrecovered cost if the program ends early.

#### How do you estimate die life for a new part?

**Answer:** Look at similar parts in the same alloy, with similar depth of cavity and press type, and use measured pieces per die set from past jobs. Add an allowance for polishing and repair. Without history, be conservative and revisit the number after the first production run.

#### Who owns forging dies?

**Answer:** It is a contract matter. Many customers pay for tooling and own it but leave it at the forge shop, while others expect the shop to carry cost in the part price. Put ownership, storage, maintenance responsibility and disposal terms in writing.
