Introduction to Twin Screw Configuration and Design

This is a Past Course

Recorded on May 14, 2019

Address complex compounding challenges (melt disturbance, surging…) by accelerating your learning curve w.r.t. extruder screw design & configuration in accordance with various polymer systems (biopolymers, additives, fillers...)

Expert Kenneth Russell will unravel the mystery of screw design. He will explore how different element designs function to ensure proper distribution & dispersion of ingredients & materials. He will also share practical tips to promote unit operations like polymer melting, mixing, devolitalization... to achieve high quality & productivity.

Why should you view this course?

You will agree that screw design is critical in ensuring that the polymer compound is made properly. But it is a complex challenge… especially, while compounding new materials. A proper design can ensure that all the ingredients are distributed properly, agglomerated materials are properly dispersed and the compound is processed at the correct melt temperature.

Not abiding to these key factors may hamper product quality and productivity. Stop trial and error and accelerate the learning curve with practical insights and a process based approach. Join now to:

  • Demystify screw design & configuration with a better understanding of extrusion science and compounding process parameters

  • Easily adapt your extruder to suit new material by better understanding how different element designs function to promote unit operations such as solids conveying, polymer melting, mixing, devolitalization, pumping…

  • Address complex challenges & troubleshoot compounding instabilities (melt disturbance, surging…) by implementing the tips & tricks from the expert

Good technical overview of compounding

Raleigh D. , from Solvay

Good fundamental approach to systematic design for twin screw configuration

Kwok N. , from SureWin

Excellent! The basics are good explained, nothing was missed. Also the screw examples are helpful!

Tim L. , from Clariant Palstics & Coatings Germany

Being a twin screw extruder user it was very useful to me. I learnt about technical specifications of screws, vents, compounding elements, etc.
