Casting Yield in Percentage Calculator

Casting Yield Percentage Formula:

\[ Y\% = \frac{W_a}{W_m} \times 100 \]

Casting Yield Percentage:

1. What is Casting Yield Percentage?

Definition: Casting Yield Percentage is the ratio of usable castings obtained from a production run to the total number of castings attempted, indicating manufacturing efficiency.

Purpose: It helps foundries and metal casting professionals measure material utilization efficiency and identify potential cost savings.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Y\% = \frac{W_a}{W_m} \times 100 \]

Where:

\( Y\% \) — Casting Yield Percentage
\( W_a \) — Actual Mass of Casting (kg)
\( W_m \) — Total Mass of Metal Poured in Mould (kg)

Explanation: The actual mass of good castings is divided by the total metal poured, then multiplied by 100 to get a percentage.

3. Importance of Casting Yield Percentage

Details: Higher yield percentages indicate more efficient material usage, reducing waste and production costs.

4. Using the Calculator

Tips: Enter the actual mass of good castings and total mass of metal poured in kilograms. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a good casting yield percentage?
A: Typically 60-85% is good for most casting processes, with investment casting often achieving 90%+.

Q2: How can I improve my casting yield?
A: Optimize gating systems, reduce pouring weight, improve mold design, and minimize scrap rates.

Q3: Does this include runners and risers?
A: No, the total mass includes all metal poured (castings + runners + risers + scrap).

Q4: Why is my yield percentage low?
A: Common causes include excessive gating systems, high scrap rates, or oversized pouring weights.

Q5: How often should I calculate casting yield?
A: Regularly monitor (weekly/monthly) to track process improvements and identify issues early.
