Abstract
The paper presents the phenomenon of injection shrinkage. The definition of shrink age and shrinkage types are presented. The main factors affecting shrinkage value of injection-molded part are discussed. Based on the experimental tests conducted using injection-molded parts made from polypropylene filled with glass fiber and talc, the dependence of injection-molded part shrinkage on filler content and selected param eters of the injection molding process has been determined.
