Gaskets, Seals, O-Rings & Elastomer Components worked example

Labor Per Batch at 110% labor allocation share: a worked example in gaskets, seals, o-rings & elastomer components

Push labor allocation share up to 110% and the picture changes. This example computes every intermediate figure at that operating point. Use it when estimating batch labor for setup, press tending, sheet feeding, demolding, trimming, post-cure handling, inspection, count packing, or lot documentation.

The inputs for this scenario

  • Batch labor hours: 18 hr (unchanged)
  • Loaded labor rate: 58 $ / hr (unchanged)
  • Labor allocation share: 110 % (raised for this scenario; the documented default is 100)
  • Fixed setup labor cost: 220 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable batch labor cost = batch labor hours × loaded labor rate × labor allocation share) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,368 $ for total labor per batch, the number this scenario is built around.
  • At this operating point the engine returns 76.02 $ / piece for labor cost per entered labor hour.
  • At this operating point the engine returns 1,148 $ for variable batch labor cost.
  • At this operating point the engine returns 220 $ for fixed setup labor cost.

How this compares with the baseline

  • Against the tool's baseline example, where labor allocation share sits at 100% and the headline result is 1,264 $, this scenario comes in 8.26% above the baseline at 1,368 $.
  • It adds the variable run labor for a batch to the fixed setup labor, giving the total labor dollars to produce one batch of elastomer parts. 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.

Results at a glance

  • Total labor per batch: 1,368 $ (headline result)
