Dear all, I like to know how to use volumetric shrinkage. Is it directly related to mold shrinkage? Attached is a picture of a sample part for your reference.
I like to know how this result is compared with the shrinkage values in the material databse. Please share your views.
Regareds, JK.
Well by definition the Volumetric Shrinkage is the sum of Parallel Shrinkage, Perpendicular Shrinkage and Thickness Shrinkage. Usually, the thickness shrinkage dominates here so the linear shrinkage is much less than 1/3 of the volumetric shrinkage. The distribution of the volumetric shrinkage between those three linear shrinkages is dependent upon many factors but usually, yes, the higher the volumetric shrinkage the higher are the linear shrinkages (at least for unfilled materials).
