Valve Body Casting Yield at 99% target casting yield: a worked example

This scenario runs the valve body casting yield calculation on the strong side: 99% target casting yield, with every other input held at its documented default. Use this when tracking foundry performance on valve body castings, reporting yield to management, or deciding whether a casting supplier needs a corrective action request.

The inputs for this scenario

  • Accepted valve body castings: 87 castings (unchanged)
  • Total valve body castings poured: 100 castings (unchanged)
  • Target casting yield: 99 % (raised for this scenario; the documented default is 92)

Working through the calculation

  • Applying the documented formula (Casting yield rate = accepted castings / total castings poured x 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 87 % for valve body casting yield rate, the number this scenario is built around.
  • At this operating point the engine returns 12 points for gap to target yield.
  • At this operating point the engine returns 87 count for accepted castings.
  • At this operating point the engine returns 100 count for total castings poured.

How this compares with the baseline

  • Against the tool's baseline example, where target casting yield sits at 92% and the headline result is 87 %, this scenario lands almost exactly on the baseline at 87 %.
  • Use it for shift or lot yield reporting, comparing pattern or alloy performance, and triggering a root-cause review when yield drops below target. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Valve body casting yield rate: 87 % (headline result)
  • Gap to target yield: 12 points
  • Accepted castings: 87 count
  • Total castings poured: 100 count
