Abstract: A 3-D nonisothermal flow field was simulated using CFD package Polyflow. The influence of different parameters of metering section on the temperature of PC melt in the injection screw was analyzed. It showed that the descending order of the influence of parameters on axial melt temperature difference was flight clearance, the angle of the inclined plane, screw channel depth, the lead of the screw, and the width of the screw flight; while the descending order of the influence on radical melt temperature difference was screw channel depth, the angle of the inclined plane, flight clearance, the lead of the screw, and the width of the screw flight.

Key words: numerical simulation, injection screws, axial melt temperature difference, radical melt temperature difference
