KraussMaffei Berstorff, in collaboration with the Institute for Polymer Extrusion and Compounding at the Johannes Kepler University in Linz (IPEC), has conducted scientific investigations on mixing systems in several simulation series. Using the consistently positive results of the investigation to optimize its single-screw extruders, the company primarily aims to further enhance the final product quality.
Dr. Ing. Otto Skrabala, a development engineer at KraussMaffei Berstorff at the Munich location, said, “The investigation clearly shows that with our philosophy put into practice over many years, we have our finger on the pulse of the manufacturers. The use of balanced mixing elements in single-screw technology has for many years been our main principle, because it guarantees the customer’s manufacture of premium-quality products.”
The influence of two elementary geometries on the feed and mixing process was investigated using numerical simulations. Based on these investigations, scientifically sound design strategies can be formulated. Factors such as the speed distribution in the flow channel, the pressure consumption or even the temperature have a decisive effect on the quality of the extrudate and the end product. Perfect homogeneity can thus be achieved only through the use of balanced mixing elements.
Dr. Skrabla, concluded, “We will continually use the consistently positive results of the study in our development activities, with the primary aim of ensuring even higher product quality for the customer with the use of our single-screw extruder.”
