June 17&18, 2020 - It's a "hands-on" seminar, not a conference!

Learn about the latest technical developments and research for melt extrusion, melt and wet granulation technologies for both pharmaceutical and nutritional products

Leistritz will host its' annual Life Science Twin Screw Seminar on June 17-18, 2020. This "hands-on" seminar starts with the basics and explains why twin screw extrusion is the preferred continuous manufacturing method to make consistent, repeatable products.


In addition to Leistritz staff, outside experts from industry and academia will contribute to the program.

Some of the topics will include:

  • Twin screw extrusion theory for melt extrusion, wet and melt granulation technologies
  • Comparison of co-rotating and counterrotating twin screw extruder systems
  • How to specify, stage, disassemble, clean, reassemble and design screws
  • Downstream systems: sizing, cooling, drying and conditioning
  • Upstream equipment: feeding, material handling and containment
  • Staging of unit operations in an extrusion system to facilitate a continuous process
  • Scale-up of the extrusion process, R&D, pilot scale and production
  • Cleaning and maintenance of extrusion equipment in a cGMP environment
  • Advantages of continuous extrusion as compared to batch processes
  • Mixing techniques for poorly soluble and heat/shear sensitive API's
  • New emerging extrusion technologies, i.e. supercritical foaming and co-extrusion


A preliminary list of outside speakers includes:

  • Feng Zhang, University of TX @ Austin
  • Mike Thompson, McMaster Univ.
  • Tony Listro, Foster Delivery Science
  • Sharon Nowak, Coperion K-Tron
  • Tom Durig, Ashland
  • John Ciasulli, Frewitt USA
  • Firouz Asgarzadeh, Evonik
  • Jim DiNunzio, Merck
  • Costas Gogos, Polymer Processing Institute
  • Steve Pafiakis, Bristol-Myers Squibb
  • Others to be added


"Hands-on" demonstrations at Leistritz process laboratory will include:

  • nano-16 twin screw extrusion system processing 50 gram batch samples
  • Film/lamination extrusion system for transdermal and dissolvable film applications
  • Foaming of an extrudate via sCO2 injection
  • Hot-face cutting of nutritional products
  • 3D filament and tube extrusion
  • Melt and wet granulation systems

A hot face pelletization demo is integrated into the program

A specialty melt granulation process will be publicly displayed for the 1st time!

Co-rotating and counterrotating twin screw extruder technologies are integrated into the seminar

Handout materials: In addition to copies of the presentations each attendee will receive a copy of the textbook Pharmaceutical Extrusion Technology, 2nd Edition.

Place: Classroom sessions are at the Holiday Inn Select in Clinton, NJ USA, and demonstrations at the nearby Leistritz Process Laboratory.

Price: $800 before May 18, 2020; $900 thereafter
