Screw Design in Plastic Extrusion - PTFE Machinery

The basic extrusion screw has three distinct parts, each engineered to do a specific task. The feed section is in the rear of the screw, where plastic pellets are gravity fed from above and conveyed forward. The length to diameter ratio of the feed section is typically four or five to one, which is sufficient to build up the pressure needed to transport the plastic.

Understanding Screw Design for Film Extrusion Process ...

Therefore, for these applications the screw should be longer to accommodate the added sections. The typical L/D ratio for screws used for film extrusion processes is 30:1. For processes where degassing is required (the so-called two stage screw), usually screws with L/D ratio of greater than 32:1 are recommended. Flight Clearance

Analyzing and Troubleshooting Single-Screw Extruders

Improper design and operation of the melting section of the screw can lead to extrusion instabilities. For example, solid bed breakup [3] can cause solids to migrate downstream. These solids can wedge into other sections of the screw and cause the extruder to flow surge [2, 4] or cause the extrudate to have periodic changes in temperature.
