Potting Material Usage with potting compound dispense rate of 30 units / hr: a worked example

What does the result look like when potting compound dispense rate reaches 30 units / hr? The full calculation is worked below with real intermediate numbers. Use it when budgeting epoxy, silicone, polyurethane, or gel potting material for inverter, converter, drive, or motor control builds.

The inputs for this scenario

  • Potting compound dispense rate: 30 units / hr (raised for this scenario; the documented default is 12)
  • Potting line runtime: 8 hr (unchanged)
  • Potting compound cost: 3.5 $ / unit (unchanged)

Working through the calculation

  • Applying the documented formula (Potting material consumed = potting dispense or use rate × potting production runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 840 $ for potting material run cost, the number this scenario is built around.
  • At this operating point the engine returns 240 units for potting material consumed.
  • At this operating point the engine returns 8 hr for potting production runtime.
  • At this operating point the engine returns 3.5 $ / unit for potting material cost.

How this compares with the baseline

  • Against the tool's baseline example, where potting compound dispense rate sits at 12 units / hr and the headline result is 336 $, this scenario comes in 150% above the baseline at 840 $.
  • A figure at this level is achievable when potting compound dispense rate is genuinely sustained, not just peaked for a shift. It assumes a steady dispense rate and ignores mix-ratio waste, purge shots, and pot-life scrap, so real consumption often runs higher.

Results at a glance

  • Potting material run cost: 840 $ (headline result)
  • Potting material consumed: 240 units
  • Potting production runtime: 8 hr
  • Potting material cost: 3.5 $ / unit
