Industrial Valves, Actuators & Flow Control calculator
Valve Body Casting Yield Calculator
Find the yield a foundry run achieves from accepted and poured casting counts. The shortfall shows how many more good castings the target asks for.
What this calculator does
- Casting yield from accepted and poured counts, with the target shortfall carried in castings.
Formula used
- Casting yield = accepted castings ÷ castings poured × 100
- Gap to target = target yield − casting yield
- Target accepted castings = target yield × castings poured ÷ 100
- Shortfall to target = target accepted castings − accepted castings
- Rejected castings = castings poured − accepted castings
Inputs explained
- Accepted Castings: Castings that passed the inspection rule for the run.
- Castings Poured: Castings poured for the run, accepted and rejected.
- Target Casting Yield: Yield rate the foundry run is measured against.
How to use the result
- Best suited to tracking a foundry run against target, sizing a gating fix before quoting, reporting casting yield to a customer.
- Scrap found after machining is outside the casting yield count. Mixed mold lines or alloys need one run per group.
Current U.S. benchmarks
- The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
Common questions
- What counts as an accepted casting? A casting that passes the inspection rule for this run, with no defect that sends it to scrap or rework. Keep the rule the same for accepted and poured counts.
- Why does the page block accepted above poured? More good castings than metal poured is impossible. Casting defects form as the metal cools, so accepted can only be a share of the poured count, never more.
- Is the gap to target in points or percent? Points. A 92% target against an 87% yield is a gap of 5 points, and the shortfall row converts that gap into castings for the same run.
- How does a target above 100% behave? It cannot be entered. The target is capped at 100%, because a yield above 100% would mean more good castings than castings poured, which is impossible.
