Modular Co-rotating Intermeshing Twin Screw Compounding Extrusion System with Multiple Feeds and Vents
Procedures are described for computation of pressure, fill factor and temperature profiles in a molular co-rotating twin screw extruder with multiple feed ports and vents. This is a modification of our earlier Akro Co-Twin Screw software. Sample calculations are given for non-isothermal flow simulation of compounding of thermoplastics with talc. It is shown that the effect of temperature on viscosity plays a significant role in pressure fill factor, and temperature profiles and in overall temperature rise.
