Study on filling patterns of engineering polymers In geometrically balanced injection molds

Filling patterns and imbalances which occur during injection molding of engineering plastics, e.g. Polyoxymethylene (POM), have been studied. Four different geometries of runner systems have been applied for experimentation. Autodesk Moldflow software has been used for finite element method (FEM) simulations of imbalance phenomenon. Evolution strategies have been suggested for optimization of runner systems in multi-cavity injection molds
