Powder Metallurgy & Sintered Parts worked example

Cost Per Sintered Part at 58% good-part yield factor: a worked example

This worked example runs the cost per sintered part numbers for a tougher week than the baseline: 58% good-part yield factor instead of the typical 80%. Cost Per Sintered Part is the fully loaded cost to make one acceptable powder-metal component, blending variable conversion cost, a yield adjustment for scrap, and fixed tooling and setup spread across the lot.

The inputs for this scenario

  • Parts in the production lot: 100 units (held at the documented default)
  • Conversion cost per part: 45 $ / unit (held at the documented default)
  • Good-part yield factor: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed tooling & setup cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Cost Per Sintered Part 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 good-part yield factor sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • Use it when quoting a PM part, comparing lot-size scenarios, or checking whether a yield improvement justifies a tooling or process change. 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.

  • Weighted cost: 2,860 $ (headline result)
