Shrinkage variation in the partTypes of shrinkage variationFrom region to region in the partThrough the thickness of the partDifferent shrinkage's parallel and perpendicular to the material orientation direction
Volumetric shrinkageDriving force behind all other shrinkage factorsModeled using PVT (pressure/volume/temperature)High cooling ratesLowers crystallinityOrientation due to fillingDifferent parallel & perpendicular shrinkageMold restraintNo shrinkage in the plane of element while in the moldTemperature differences through the thicknessCausing bending moments
