Extrusion Equipment Engineering for PLA: Theory and Practice
This workshop will provide and approach for properly engineering extruder screws and dies for processing PLA resins. The important material properties will be discussed, and the appropriate design criteria will be defined. Then, we will demonstrate how we apply the design criteria to perform engineering calculations for single screw extruder, and flow channel, design and optimization. The above will be taught through a troubleshooting approach in which poor designs are investigated and new designs are proposed and then verified via simulation and empirically.
Outline of Workshop:
• Introduction to PLA rheology
• Process Design Criteria
• Extruder Performance and Mixing
• Adaptor and Die (Flow Channel) Optimization
• Troubleshooting
