摘要: The extrusion process is fundamental to the production of vast majority polymer and composite products in plastics industry. delivery a melt which homogenous composition temperature paramount for achieving high quality extruded products. However, melting stability can be difficult monitor/control via typical thermocouple measurements as they provide only single point measurement flow. Previous studies have shown that die changes considerably across based are not sufficient determine thermal homogeneity. In this work, profile monitored by mesh technique data obtained used formulate linear/nonlinear models predict effects settings on homogeneity screw extruder. A static nonlinear polynomial model developed, shows good agreement with measured provides straight forward approach investigating individual processing parameters flow
