Leistritz Extrusion is hosting a Bioplastics Twin-Screw Extrusion Workshop at The Polymers Center. Classroom sessions conducted by Leistritz staff will be supplemented by interactive extrusion system demonstrations, as well as screw assembly, equipment cleaning, and maintenance procedures.
Bioplastic and natural-fiber formulations are heat and shear sensitive, and often require multi-stage venting. On the first day, topics tailored specifically to processing bioplastics will be discussed. This will be followed on day two with hands-on demonstrations at The Polymers Center lab illustrating some of those issues. The topics include:
- Co-rotating and counter-rotating twin-screw extrusion technology;
- techniques for dispersive and/or distributive mixing (with minimization of heat/shear);
- sequencing of multi-stage process operations;
- devolatilization process techniques and practices;
- scale-up of the twin-screw extrusion process;
- feeders 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;
- foaming of bioplastics;
- co-extrusion;
- process troubleshooting;
- twin-screw extruder maintenance tips and procedures;
- control and monitoring options.
