MANUFACTURING – CATING & FOUNDRY CALCULATOR
Casting Yield
A precise tool.
What is the Casting Yield & How does it work?
In casting operations, the total poured weight (often called the gross weight) comprises the metal that will become the final part as well as the metal that remains in the gating system and risers.
The net weight of the usable casting is obtained by subtracting the gating weight and the riser weight from the gross weight. This net weight directly reflects the amount of material that can be machined or finished into a functional component.
Yield percentage is a key performance indicator for foundries because it quantifies material efficiency, influences production cost, and helps identify opportunities for process optimisation.
Y = frac{W_{net}}{W_{gross}} times 100
Y = casting yield (%)
W_{net} = W_{gross} – W_{gating} – W_{riser}
W_{gross} = total poured weight (kg)
W_{net} = W_{gross} – W_{gating} – W_{riser}
W_{gross} = total poured weight (kg)

Frequently Asked Questions
What is casting yield?
Casting yield is the percentage of usable metal from the total poured weight, reflecting material that can be machined into a functional component.
How do I calculate casting yield?
Subtract gating and riser weights from gross weight, then divide by gross weight and multiply by 100 to get the percentage.
Why is casting yield important?
Casting yield is crucial for assessing material efficiency and reducing waste in manufacturing processes.
Can casting yield be improved?
Yes, by optimizing gating systems, minimizing riser sizes, and improving pouring techniques to reduce metal loss.
What factors affect casting yield?
Factors include the design of the casting mold, pouring temperature, and the type of metal being cast.
How does casting yield impact production costs?
Higher casting yield reduces material waste and can lower production costs by using less raw materials.
What is a good casting yield percentage?
A good casting yield varies by industry, but generally, higher percentages indicate more efficient use of materials.
