Mold Cavitation Output at 99% effective cavitation efficiency: a worked example

This scenario runs the mold cavitation output calculation on the strong side: 99% effective cavitation efficiency, with every other input held at its documented default. Use it when a mold has blocked cavities, short shots, knit-line rejects, flash problems, venting issues, or cavity imbalance and the team needs a defensible output rate.

The inputs for this scenario

  • Molded parts completed: 1,850 parts (unchanged)
  • Mold runtime: 8 hr (unchanged)
  • Effective cavitation efficiency: 99 % (raised for this scenario; the documented default is 92)

Working through the calculation

  • Applying the documented formula (Raw mold cavitation output = molded parts completed รท mold runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 229 units / hr for effective mold cavitation output, the number this scenario is built around.
  • At this operating point the engine returns 231 units / hr for raw molded output rate.
  • At this operating point the engine returns 99 % for effective cavitation efficiency.
  • At this operating point the engine returns 8 hr for mold runtime.

How this compares with the baseline

  • Against the tool's baseline example, where effective cavitation efficiency sits at 92% and the headline result is 213 units / hr, this scenario comes in 7.61% above the baseline at 229 units / hr.
  • Use it to set or audit a molding rate standard, or to compare two tools on a common units-per-hour basis. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Effective mold cavitation output: 229 units / hr (headline result)
  • Raw molded output rate: 231 units / hr
  • Effective cavitation efficiency: 99 %
  • Mold runtime: 8 hr
