The material-inherent specific volume behavior of polymers is highly important for producing dimensionally accurate injection molded parts since the shrinkage and the shrinkage-induced warpage are attributable to the specific volume behavior. Thereby

In the extrusion of plastics, the thermal and material homogeneity of the plastic melt at the die entry are of high importance for the extrudate quality. While static mixers are widely used to improve the melt homogeneity, previous attempts at optimi
