Casting Yield & Pouring Weight Calculator
Calculate casting yield (net ÷ poured) or the poured/melt weight from net weight and yield — the figure that drives melt cost and gating design.
Method
Typical yields
| Process | Yield |
|---|---|
| Investment casting | 50–70% |
| Sand casting | 55–75% |
| Die casting | 60–85% |
Frequently Asked Questions
What is casting yield?
The ratio of finished (net) casting weight to total poured (melt) weight, expressed as a percentage. The rest is gating, runners and risers.
How do I improve casting yield?
Optimize gating and risering, use chills and exothermic sleeves, and consolidate parts — higher yield means less remelt and lower cost.
What is a good yield?
Investment casting is typically 50–70%; higher is better but must still feed the casting soundly.
Why does poured weight matter?
You pay to melt the full poured weight, so it drives material and energy cost more than the net part weight.
