Leistritz Twin Screw Extrusion Workshop, November 28-29, 2018

Leistritz will host its’ annual Twin Screw Extrusion Workshop on Nov. 28-29, 2018 in NJ.  As always, classroom sessions are supplemented by “hands-on” twin screw extrusion operating experience. A partial list of topics is as follows:

  • Co-rotating and counterrotating twin screw extrusion technology
  • High speed, energy input (HSEI) twin screw extruder theory and design
  • Comparison to low speed, late fusion (LSLF) designs
  • Screw design and process techniques
  • Techniques for dispersive and/or distributive mixing
  • Sequencing of multi-stage process operations
  • Devolatilization process techniques and practices
  • Scale-up of the twin screw extrusion process
  • Feeder and material handling for pellets, powders and liquids
  • Gear pumps and screen changers
  • Pelletizing: strand cut, water ring, and underwater
  • Direct extrusion for sheet, film, fibers and profiles
  • Reactive processing
  • Process troubleshooting
  • Control and monitoring options
  • Screw assembly and disassembly
  • Twin screw extruder maintenance tips and procedures

“Hands-on” demonstrations at Leistritz NJ process laboratory will include:

  • Co-rotating and counterrotating twin screw extruders
  • Devolatilization via extrusion: ambient, vacuum assist, multi-stage
  • Downstream addition of fillers, fibers and additives
  • Direct sheet/film extrusion with gear pump front-end
  • Foam extrusion via supercritical injection
