Question

difference between solid and liquid shrinkage

Answer 1

shrinkage during solidification, and (c) shrinkage in the solid state. ... difference between the specific volume of the solid metal and of the liquid metal at the melting point is the shrinkage during solidification.

Answer 2

Explanation:

Liquid shrinkage is the contraction that occurs as the alloy cools but remains in its liquid state. This is not normally significant from a casting design perspective.

Solid shrinkage is the continued shrinkage that occurs as the solid metal casting cools to ambient temperature in its solid state. This is also significant from the designer’s point of view. It is known as “Patternmaker’s Shrinkage” and must be compensated for within the tooling or mould design to ensure that the specified final overall dimensions are achieved.
