The ITXtrude© program is a simulation package
incorporated into session 7 of ITX©. ITXtrude©, allows students to determine
important parameters of the extrusion process, such as shear rate, solids
conveying rate, melting rate, drag and pressure flow rate, and characteristics
curves (see image 1 below). A user friendly, point-and-click approach
allows the user to apply this information to actual extrusion operations and
to make sophisticated calculations without having to struggle through complex
equations. The screen for the characteristic curves actually shows
an animation of a rotating screw, while also graphically showing the output
versus pressure curves for the extruder and the die (see images 2 and 3 below).
