Extrusion die design

As stated above, extrusion die design is a complex task because the extrudate product dimensions depend not only on the die design (die shape), but also on the polymer properties and extrusion process parameters. The following are general recommendations for extrusion die design ...

Is this really so Has this been simply an exercise in intellectual beauty, satisfying the curiosity, or can one hope for a practical result Will the insights developed in explaining negative lead to an unexpectedly effective extrusion die design or processing technique When one of us (G. Kiss) was a graduate student at the University of...

More than 90% of PVC pipe is produced on twin-screw extruders. Two types of extrusion dies for pipe are shown in Figure 10.3. In the modern design (Figure 10.3a), a more uniform flow and less back pressure occurs. There are three important factors in extrusion die design the pressure drop, the shear rate, and the residence time.
