Worked example

Inputs

Casting volume: 100 cm³
Cooling surface area: 100 cm²
Calibrated mold constant: 2 min/cm^n
Calibrated exponent: 2

Expected results

Casting modulus: 1 cm
Estimated solidification duration: 2 min

How to use this tool

Enter every input in the labeled units; use measured or independently specified properties.
Check the stated model assumptions before calculating.
Interpret the output as a model estimate and verify it independently for the intended application.

Try this example

{
  "volume": 100,
  "area": 100,
  "constant": 2,
  "exponent": 2
}

Accuracy and scope

Empirical mold/material calibration required; excludes feeding, hot spots and shrinkage-porosity assessment. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
