How do I calculate tooling cost per part?

Tooling Amortization divides the tool build cost by the parts it will produce over its life or the committed program volume, whichever is smaller. Mold Cost Per Part and Die Cost Per Part refine this by adding tool life limits, refurbishment intervals, and residual value. If a mold costs 80,000 dollars and the program is 400,000 parts, the amortized tooling is 0.20 dollars per part before any wear or maintenance is added.

When does adding mold cavities lower cost per part?

Mold Cavitation Economics weighs the higher build cost and larger press of a multi-cavity tool against the cycle time saved per part. More cavities cut the amortized machine time per part but raise tool cost and maintenance. It pays off at high volume, where the per-part machine time savings outrun the extra Tooling Amortization. At low volume a single-cavity tool usually wins because the cavity investment never amortizes.

How do I justify the ROI on a new fixture?

Fixture ROI compares the fixture build cost against the savings it generates: reduced setup and load time, lower scrap from better repeatability, and freed labor. Fixture Payback converts that into the number of parts or months to recover the build cost. A fixture that cuts two minutes of load time per part and Fixture Utilization stays high will pay back quickly at production volume; low utilization stretches payback and may argue for a simpler fixture.

How do I estimate tool life and its cost impact?

Die Life Estimator and Tool Life Cost project how many hits or parts a die or insert delivers before rebuild or replacement, based on material, tonnage, and wear rate. Insert Replacement Cost and Preventive Tooling Maintenance turn that wear into a per-part cost. Spreading a 12,000 dollar die refurbishment over a 500,000 hit life adds about 0.024 dollars per part, which belongs in the true cost model alongside amortization.

What does changeover cost me on a die or mold?

Die Changeover Loss and Mold Changeover Cost combine the changeover labor, the lost production time on the press, and any scrap during startup. Multiply the downtime by the machine hour rate to get the real cost of each swap. This is what SMED programs target: reducing a 90 minute mold change to 30 minutes recovers an hour of press capacity per changeover, which Tool Downtime Cost values against your production rate.

How do I know if my toolroom can keep up with demand?

Toolroom Labor Load and Tooling Capacity compare the maintenance, repair, and new-build hours required against the toolmaker hours available. Tooling Backlog shows the queue building up when demand exceeds capacity, which is an early warning of production tools going down without a repaired spare. Pair it with Spare Tooling Inventory and Tooling Repair Cost to decide whether to add toolroom capacity or outsource overflow work.

Manufacturing calculator category

Tooling, Fixtures, Dies & Mold Economics calculators

This category covers the economics of the hard tooling that makes parts: molds, dies, fixtures, and the toolroom that keeps them running. It is for tooling engineers, cost estimators, and toolroom managers who need to justify a tool build, spread its cost across the right volume, and stay ahead of maintenance and backlog.
