Mould Shrinkage

The immediate shrinkage which a moulded part undergoes when it is removed from a mould and cooled to room temperature; the difference in dimensions, expressed in inches per inch between a moulding and the mould cavity in which it was moulded (at normal temperature measurement); the incremental difference between the dimensions of the moulding and the mould from which it was made, expressed as a percentage of the dimensions of the mould.
