 Plastic shrinkage characteristics and influencing factors of thermoplastics is heated expansion, contraction after cooling, of course, after pressing the volume will be reduced. In the injection molding process, molten plastic is first injected into the mold cavity, after the end of filling the melt is cooled and solidified, i.e. contraction removed plastic parts from the mold, this contraction is called molding shrinkage. Plastic parts removed from the mold into the stable this time manhole cover mold, the size will still be minor changes, a change is to continue to shrink, shrink after this contraction is called.
