The company I work for extrudes plastic sheet. We recently had a fatigue failure of one of our extruder screws. The fatigue zone was roughly halfway through the screw. We have other, old machines that may also be wearing in this way. Does anyone know of a way to test the screw continuity while it's still in the extruder? I would like to be able to test the screws for cracks without having to pull and clean the screws. Any ultrasonic methods available?
Any guidance is appreciated.
