Mold Cavitation Output at 66% effective cavitation efficiency: a worked example

This worked example runs the mold cavitation output numbers for a tougher week than the baseline: 66% effective cavitation efficiency instead of the typical 92%. Estimate effective molded seal output per hour from completed parts, runtime, and realistic cavitation efficiency.

The inputs for this scenario

  • Molded parts completed: 1,850 parts (held at the documented default)
  • Mold runtime: 8 hr (held at the documented default)
  • Effective cavitation efficiency: 66 % (the input this scenario stresses; the baseline uses 92)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw mold cavitation output = molded parts completed รท mold runtime.
  • Effective mold cavitation output works out to 153 units / hr at these inputs, and this is the headline figure for the scenario.
  • Raw molded output rate works out to 231 units / hr at these inputs.
  • Effective cavitation efficiency works out to 66 % at these inputs.
  • Mold runtime works out to 8 hr at these inputs.

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 28.26% below the baseline at 153 units / hr.
  • Use it to set or audit a molding rate standard, or to compare two tools on a common units-per-hour basis. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Effective mold cavitation output: 153 units / hr (headline result)
  • Raw molded output rate: 231 units / hr
  • Effective cavitation efficiency: 66 %
  • Mold runtime: 8 hr
