Effects of Geometry Variations on the Mixing Ability of Shear-Mixing-Type Screw Head

Description

In the single screw plasticizing unit of an injection molding machine the preparation of a melt cushion during the plasticizing process, with both a good thermal and optical homogeneity is a challenging task. Thus it is common to use mixing heads to improve the melt homogeneity in the screw chamber. However, due to the complex flow patterns in mixing heads the optimization of the mixing head geometry with respect to its mixing ability is cumbersome. In the presented work a DOE (Design of Experiment) study has been performed to analyze effects of geometry variations and processing conditions on the mixing ability of a so called Shear-Mixing-Head by means of CFD methods.
