<p>In an extrusion process, desired product quality parameters are maintained very accurately by manipulating the rotational speed of the screw associated with the extrusion process so as to maintain a desired ratio of feed rate to drag flow in the extrusion process and by manipulating the feed rate of the material to the extrusion process so as to maintain a desired energy input per unit of the material being processed.</p> |
