Dynamics Analysis of the Melt Conveying Process in a Novel Extruder

Abstract EN

This study investigates dynamics of the melt conveying process in a novel extruder in which a polymer experiences a primarily elongational deformation field.

The working principle of the novel extruder is completely different from that of conventional screw extruders.

At the last stage of polymer processing in the proposed novel extruder, melt is conveyed through feeding and discharging processes.

Here we present a mathematical model to analyze dynamics in the melt conveying process.

Melt extrusion is primarily influenced by the position of vane chamber and the structural parameters of the novel extruder such as eccentricity.
