Tooling, Fixtures, Dies & Mold Economics worked example

Mold Cavitation Economics at 65% molding machine uptime: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop molding machine uptime to 65%, then walk the calculation through step by step. Estimate mold cavitation economics for tooling, fixtures, dies and mold economics using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Parts per mold shot (cavity count): 4 units / cycle (held at the documented default)
  • Rated mold shots before service: 480 cycles (held at the documented default)
  • Molding machine uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Molded part first-pass yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross mold cavitation economics capacity = mold cavitation economics output per cycle × available mold cavitation economics cycles.
  • Good mold cavitation economics capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross mold cavitation economics capacity works out to 1,920 units at these inputs.
  • Mold cavitation economics downtime loss works out to 672 units at these inputs.
  • Mold cavitation economics yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where molding machine uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to molding machine uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes every cavity runs and yields equally; a blocked or short-filling cavity, or family-mold imbalance, will make real good output fall below the estimate.
