Valve Body Casting Yield at 66% target casting yield: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target casting yield to 66%, then walk the calculation through step by step. Calculate valve body casting yield rate and gap to target from accepted castings vs. total castings poured, helping foundry and quality teams track performance and trigger corrective actions.

The inputs for this scenario

  • Accepted valve body castings: 87 castings (held at the documented default)
  • Total valve body castings poured: 100 castings (held at the documented default)
  • Target casting yield: 66 % (the input this scenario stresses; the baseline uses 92)

Working through the calculation

  • The calculation starts from the formula this tool documents: Casting yield rate = accepted castings / total castings poured x 100.
  • Valve body casting yield rate works out to 87 % at these inputs, and this is the headline figure for the scenario.
  • Gap to target yield works out to -21 points at these inputs.
  • Accepted castings works out to 87 count at these inputs.
  • Total castings poured works out to 100 count at these inputs.

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 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target casting yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It is a simple acceptance ratio and does not weight castings by size or value, so a low yield on heavy high-alloy bodies costs far more than the same percentage on small carbon-steel bodies.

Results at a glance

  • Valve body casting yield rate: 87 % (headline result)
  • Gap to target yield: -21 points
  • Accepted castings: 87 count
  • Total castings poured: 100 count
