Mix and meet with screw design experts!

Including an Afternoon Tour of
UMass Lowell Extrusion Process Laboratories
on Day 2

SPE Screw Design Conference Highlights
Event Highlights
  • Cocktail Reception on Day 1
    Mix-and-meet with the SPE Extrusion board, UML staff, speakers and attendees
  • UMass Extrusion Process Lab Tour on Day 2
    Take an afternoon tour of the UMass Lowell Extrusion Process Laboratory, transportation included
This program will allow you to gain insight into the art of screw design. More importantly, you’ll soon be able to help anyone responsible for an extrusion operation to evaluate an existing process or to prepare for future projects.
Co-hosted by the Society Plastics Engineers (SPE) Extrusion Division and the SPE Eastern New England Section, the SPE Screw Design Conference-Topcon will focus on screw design principles for single- and twin-screw extruders for any type of extrusion operation in any industry. Areas of focus will include screw designs for precision extrusion, melt temperature management, minimization of gels, and useful techniques and practices to process bioplastics, recycled materials and foamed parts. In addition to the technical sessions, there will be a reception on Day 1, and a Day 2 tour of the UMass Lowell Extrusion Process Laboratory.
