Casting Cleaning Labor with cleaning labor hours per hour of casting production of 7.5 hr / hr: a worked example

Push cleaning labor hours per hour of casting production up to 7.5 hr / hr and the picture changes. This example computes every intermediate figure at that operating point. Use it when cleaning room labor affects cost per casting, quote margin, or schedule capacity.

The inputs for this scenario

  • Cleaning labor hours per hour of casting production: 7.5 hr / hr (raised for this scenario; the documented default is 3)
  • Cleaning department runtime this run: 8 hr (unchanged)
  • Burdened cleaning labor cost: 38 $ / hr (unchanged)

Working through the calculation

  • Applying the documented formula (Casting Cleaning Labor consumed = cleaning labor hours per hour of production × cleaning runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,280 $ for casting cleaning labor run cost, the number this scenario is built around.
  • At this operating point the engine returns 60 units for casting cleaning labor consumed.
  • At this operating point the engine returns 8 hr for cleaning runtime.
  • At this operating point the engine returns 38 $ / unit for burdened cleaning labor cost.

How this compares with the baseline

  • Against the tool's baseline example, where cleaning labor hours per hour of casting production sits at 3 hr / hr and the headline result is 912 $, this scenario comes in 150% above the baseline at 2,280 $.
  • It computes the burdened cleaning-labor cost of a run by multiplying cleaning hours per production hour by runtime, then by the fully burdened hourly cleaning rate. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
