<p>EXTRUDER SCREW The extruder screw has a solid feed section followed by a solid-melt transition section, followed by a melt metering section. A solid feed channel extends from the feed end of the extruder screw up to a point within the solid-melt transition section. A solid-melt channel extends longitudinally from the beginning to the end of the solidmelt transition section. A melt channel begins within the solid-melt transition section just after the end of the solid feed channel and extends longitudinally to the end of the melt metering section.</p> |
