Extrusion Flow Stability
Vol. 26 #1, March 1999
Poor extrusion stability can be caused by feed bridging in the hopper or insufficient inlet pressure to the extruder. If feed bridging is the cause, then the feed hopper level should be kept to a minimum. If too low an inlet pressure is the cause, then the feed hopper level should be maximized. Therefore, for debugging flow stability problems, extremes of feed hopper level should be tried.
