How is the shrinkage allowance calculated?
Calculate the shrinkage percentage after determining the original size and the end size. Subtract the final size from the original size to find the amount of the shrinkage. Multiply the shrinkage rate by 100 to find the shrinkage as a percentage. In the example, multiply 0.25 by 100 to get 25 percent.

What is the purpose of a riser?

What is metal shrinkage?
Metal shrinks as it transforms from liquid to solid (known as solidification shrinkage) and undergoes additional thermal contraction as it cools to room temperature. Cast parts are therefore designed with shrinkage allowances to result in parts of the desired dimensions. Cast steel, for example, will shrink about ¼ in.
