Foundry & Forging worked example

Casting Yield at 83% target casting yield: a worked example

This scenario runs the casting yield calculation on the strong side: 83% target casting yield, with every other input held at its documented default. Use it when a foundry manager, process engineer, or estimator needs to quantify how much poured metal becomes saleable castings after gates, risers, scrap, and rework.

The inputs for this scenario

  • Good casting output: 4,200 lb (unchanged)
  • Total poured or produced metal: 6,000 lb (unchanged)
  • Target casting yield: 83 % (raised for this scenario; the documented default is 72)

Working through the calculation

  • Applying the documented formula (Casting Yield rate = good casting output ÷ total poured or produced metal × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 70 % for casting yield rate, the number this scenario is built around.
  • At this operating point the engine returns 13 points for casting yield gap to target.
  • At this operating point the engine returns 4,200 count for good casting output.
  • At this operating point the engine returns 6,000 count for total poured or produced metal.

How this compares with the baseline

  • Against the tool's baseline example, where target casting yield sits at 72% and the headline result is 70 %, this scenario lands almost exactly on the baseline at 70 %.
  • Use it per heat, per pattern, or as a plant rolling average to see how much of your melted metal actually becomes shippable product. 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

  • Casting Yield rate: 70 % (headline result)
  • Casting Yield gap to target: 13 points
  • Good casting output: 4,200 count
  • Total poured or produced metal: 6,000 count
