Dynamics that Affect the Shrinkage of Injection Molded Parts
All mold engineers know, shrinkage is an unfortunate fact of life. All plastics shrink as they cool from viscous liquids to solids, and every type of plastic shrinks in a slightly different way. And while eliminating shrinkage is impossible, minimizing it is essential for molding parts accurately.
