Abstract: The three-dimensional nonisothermal melt flow fields in metering section of injection and extrusion during plasticizing process were simulated by Polyflow. Comparisons of their temperature, viscosity, velocity and pressure fields showed that distributions of temperature and viscosity in extrusion were more homogeneous and more stable than injection. The back motion of screw is favorable for increasing melt transportation.
