A Research on the Relationship of Screw Speed and Extrusion Pressure

Abstract:

When extrusion molding, the pressure fluctuations within the nose is the largest problem in the extruder production. In the present, we use mainly to change speed to adjust the pressure fluctuations, but knowledge is still relatively scarce on relation between the speed and pressure. By CFX fluid simulation of flow field distribution in extruder based on PVC production, we obtain the law of pressure with the change of speed, which provide guidance for the control of press inside the extruder.
