Abrasive wear manifests itself differently depending on which part of the screw/barrel is affected (e.g. feed section, melting/mixing sections, die pumping section). In each of these cases, the results of wear are described in terms of how extruder wear affects product quality and/or productivity. Every compounding machine operator and plant engineer should know how to recognize the symptoms of abrasive wear!
This webinar details the procedures for conducting wear measurements on extruder screws and barrels, which should be an integral part of your preventive maintenance program. Techniques and tooling are described for obtaining an accurate picture of the condition of your machine, critical for proactive replacement of components prior to failure.READ MORE
