Extruder Screw is the heart of the extruder and it is very important to specify the correct design and construction materials. Many extruders are supplied with general purpose designs and many others are supplied with designs that are far from optimized. Extrusion screws tend to have greater shear capability, resulting from the increased use of barrier designs and the utilization of a grooved feed zone in the barrel. A shallow feed zone channel in the screw in combination with a grooved feed section in the barrel also creates shear and a more aggressive feeding of the material.
