<p>HIGH OUTPUT EXTRUDER SCREW A high output extruder screw which produces high throughputs and increased melting efficiency. The screw has a feed, transition and a meter section. The transition section includes a series of alternating compression and relief zones. Each compression zone has a decreasing channel depth and each relief zone has an increasing channel depth. This promotes rapid melting of the polymer while maintaining low extrudate temperatures and allows higher screw speeds to increase throughput.</p> |
