How to Use Chvorinov’s Rule Calculator

Using the Chvorinov’s Rule Calculator involves the following steps:

  1. Enter Mold Constant (B): Input the mold constant specific to the casting material and process.
  2. Enter Volume of the Casting (V): Input the volume of the casting in cubic centimeters (cm³).
  3. Enter Surface Area of the Casting (A): Input the surface area of the casting in square centimeters (cm²).
  4. Calculate Solidification Time (T): Click on the calculate button to obtain the estimated solidification time.

The calculator applies Chvorinov’s Rule formula: T=B×(VA)T = B \times \left(\frac{V}{A}\right)T=B×(AV​), where BBB is the mold constant, VVV is the volume of the casting, and AAA is the surface area of the casting.
