Powder Metallurgy & Sintered Parts worked example

Labor Per Batch at 58% operator attendance and staffing factor: a worked example in powder metallurgy & sintered parts

Suppose operator attendance and staffing factor falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Labor Per Batch quantifies the direct labor a powder metallurgy shop spends to press, sinter, and finish one production batch.

The inputs for this scenario

  • Parts produced per batch: 100 units (held at the documented default)
  • Direct labor rate per part: 45 $ / unit (held at the documented default)
  • Operator attendance / staffing factor: 58 % (the input this scenario stresses; the baseline uses 80)
  • Batch setup & changeover labor: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Labor Per Batch cost = quantity × rate × capture factor + fixed cost.
  • Weighted cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Per piece value works out to 28.6 $ / piece at these inputs.
  • Captured value works out to 2,610 $ at these inputs.
  • Fixed adjustment works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where operator attendance and staffing factor sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • It computes total batch labor from a per-part labor rate scaled by an operator staffing factor, plus a fixed setup and changeover labor charge. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
