I was wondering if anyone knows if / what relationship exists between wearing ZME (WP thermal mixing element) elements and the resulting tensile strength of a given product. Is it a gradual effect as seen with a single screw mixer, or is it immediate? We recently had an issue regarding a 50% loss in physicals on a glass-filled PA6; needless to say the FG supplier claims that their strand integrity is above board. Despite the PdM program that is peformed qurterly on the extruder screws, the focus is shifting to the ZME elements. If anyone has any similar experiences or any knowledge regarding this issue, it would be greatly appreciated.
