This two-day seminar is based on Screw Rotation Physics and is specifically designed for plastics practitioners and professionals who need to understand the technology of single-screw extruder design and analysis.
The course will cover basic extruder design, screw design fundamentals, and extruder operation as they apply to stand alone extruders, injection molders and “compounding/mixing” in single screw devices. Topics to be covered are solids conveying, melting, metering, mixing, viscosity effects, material degradation and temperature rise in single-screw extruders.
Numerous troubleshooting case studies will be presented that deal with topics such as black specs, gel contamination, flow surging, and the effect of power-law polymers on predicted rate.
Seminar Takeaways |
- Why metering section must control rate

- Temperature control
- Metering of power law polymers
- Sources of gels and black specks
