Foundry & Forging calculator

Casting Yield Calculator

Calculate casting yield by comparing finished good casting weight or good casting count against total poured or produced weight/count. 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.

What this calculator does

  • Calculate casting yield by comparing finished good casting weight or good casting count against total poured or produced weight/count.
  • 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.
  • Measures how effectively poured metal turns into accepted castings.

Formula used

  • Casting Yield rate = good casting output ÷ total poured or produced metal × 100
  • Casting Yield gap to target = calculated rate - target casting yield

Inputs explained

  • Good casting output: Enter accepted casting weight or good casting count after shakeout, cutoff, cleaning, inspection, and rework decisions.
  • Total poured or produced metal: Use total pour weight, melt issued, or castings produced for the same alloy, part number, heat, mold line, or lot.
  • Target casting yield: Use the routing standard, quote assumption, historical yield, or improvement target.

How to use the result

  • Use for daily foundry KPIs, estimating, and process improvement.
  • This calculator is an estimating tool. Results can change with alloy chemistry, furnace practice, ladle losses, mold design, gating and riser layout, core condition, pattern allowance, die temperature, press condition, inspection criteria, rework rules, energy rates, labor standards, and actual shop performance. Validate safety-critical, metallurgical, tooling, press-capacity, and customer-spec decisions with qualified engineering, metallurgy, OEM data, and the applicable control plan.

Common questions

  • What information do I need before using the Casting Yield? Use good casting output, total poured or produced metal, and the target yield on the same weight or count basis.
  • What does the result mean? It shows actual casting yield and the gap to the target yield.
  • When is the result only an estimate? This calculator is an estimating tool. Results can change with alloy chemistry, furnace practice, ladle losses, mold design, gating and riser layout, core condition, pattern allowance, die temperature, press condition, inspection criteria, rework rules, energy rates, labor standards, and actual shop performance. Validate safety-critical, metallurgical, tooling, press-capacity, and customer-spec decisions with qualified engineering, metallurgy, OEM data, and the applicable control plan.
  • What decision can I make from the result? Use it to improve gating/riser design, quote material usage, track melt yield, or flag scrap and rework problems.
