Composites, Fiberglass & Advanced Materials calculator

Composite Tool Life Cost Calculator

Use this calculator to spread mold, plug, mandrel, fixture, trim tool, or cure tool cost over expected good pulls or production parts.

What this calculator does

  • Estimate cost assigned to composite molds or tools over their usable life.
  • allocating tool cost across composite production volume
  • The result estimates tool-life cost allocated to the selected production scope.

Formula used

  • Variable composite tool life cost = good tool pulls or parts planned × tool-life cost per pull or part × tool cost scope included
  • Total composite tool life cost = variable composite tool life cost + fixed tool maintenance and storage cost

Inputs explained

  • good tool pulls or parts planned: Use expected acceptable pulls, cycles, panels, blades, hulls, or parts over the tool-life horizon.
  • tool-life cost per pull or part: Use mold build cost, refurbishment cost, repair cost, or depreciation basis per good output.
  • tool cost scope included: Use 100% for full tool cost or less for one cavity, insert, fixture, trim tool, or customer scope.
  • fixed tool maintenance and storage cost: Include release refurbishment, repairs, dimensional recertification, storage, handling, and calibration.

How to use the result

  • Use it for quoting, tool replacement timing, refurbishment decisions, and low-volume program cost review.
  • Treat the result as a planning estimate until it is checked against the approved laminate schedule, material datasheets, ply books, resin batch records, tool condition, cure logs, inspection results, customer specification, and actual shop observations for the same part family and process.

Common questions

  • What is the composite tool life cost calculator for? Use this calculator to spread mold, plug, mandrel, fixture, trim tool, or cure tool cost over expected good pulls or production parts.
  • What information should I enter? Enter good tool pulls or parts planned, tool-life cost per pull or part, the included scope percentage, and any fixed tooling, setup, freight, qualification, or engineering cost assigned to the estimate.
  • What does the result tell me? The result estimates tool-life cost allocated to the selected production scope.
  • When is the result only an estimate? Treat the result as a planning estimate until it is checked against the approved laminate schedule, material datasheets, ply books, resin batch records, tool condition, cure logs, inspection results, customer specification, and actual shop observations for the same part family and process.
