Composites, Fiberglass & Advanced Materials calculator
Tooling Amortization Calculator
Use this calculator to connect mold cavities, planned pulls, tool availability, and first-pass yield to good parts produced for spreading tool cost.
What this calculator does
- Estimate good part capacity over composite mold or tool cycles for amortization planning.
- planning mold cost recovery across usable composite parts
- The result estimates good parts available to absorb mold or tool cost.
Formula used
- Gross tooling amortization = good parts possible per tool cycle × planned tool cycles for amortization
- Good tooling amortization = gross output × tool availability during amortization period × tool-cycle first-pass yield
Inputs explained
- good parts possible per tool cycle: Use cavities, panels per pull, blade sections per mold, or parts per press cycle.
- planned tool cycles for amortization: Use expected mold pulls, autoclave loads, press cycles, or production cycles over the amortization horizon.
- tool availability during amortization period: Account for mold cleaning, repair, release renewal, dimensional checks, maintenance, and schedule conflicts.
- tool-cycle first-pass yield: Use the percent of tool cycles expected to produce acceptable parts without scrap or major repair.
How to use the result
- Use it to set tooling amortization assumptions, quote low-volume parts, and compare single-cavity versus multi-cavity tools.
- 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 tooling amortization calculator for? Use this calculator to connect mold cavities, planned pulls, tool availability, and first-pass yield to good parts produced for spreading tool cost.
- What information should I enter? Enter good parts possible per tool cycle, planned tool cycles for amortization, expected process availability, and first-pass yield for the same mold, cell, oven, autoclave, or layup operation.
- What does the result tell me? The result estimates good parts available to absorb mold or tool cost.
- 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.
