Powder Metallurgy & Sintered Parts worked example

Powder Loss Rate at 99% target maximum loss rate: a worked example

Push target maximum loss rate up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when powder loss rate in powder metallurgy and sintered parts needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Powder lost or scrapped (mass or parts): 8 units (unchanged)
  • Total powder charged or parts run: 250 units (unchanged)
  • Target maximum loss rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Powder Loss Rate rate = affected amount รท total amount) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for gap to target.
  • At this operating point the engine returns 8 count for affected count.
  • At this operating point the engine returns 250 count for total count.

How this compares with the baseline

  • Against the tool's baseline example, where target maximum loss rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes powder loss as a percentage of total powder charged (or parts run) and shows the gap between that rate and your target loss ceiling. 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

  • Rate: 3.2 % (headline result)
  • Gap to target: 95.8 points
  • Affected count: 8 count
  • Total count: 250 count
