About the Seminar
The seminar covers twin screw extrusion compounding in a broad sense. Material issues will be covered as well as machinery issues. Various types of compounders will be discussed; however, the main focus will be on co-rotating twin screw extruders. Functions of a co-rotating TSE will be discussed in detail to develop a good understanding of what happens inside a TSE and how the process can be influenced by process conditions and machine geometry.
Screw design for TSE will be discussed in detail. Also, scale-up of TSE will be covered with several examples. Operation and optimization of TSE will be part of the seminar. Troubleshooting will be an important section of the seminar. Attendees are encouraged to bring extrusion problems to the seminar so that these can be discussed in the troubleshooting section. Finally, maintenance issues will be covered such as gear box maintenance, screw and barrel sections, and preventive maintenance.
Who Should Attend this Seminar
This is designed for technicians and engineers that work on twin screw compounders and for maintenance personnel. They will learn to set up and run the machine correctly and to optimize the process. Attendees will learn how to correctly arrange screw elements along the shaft to achieve certain process objectives. Attendees will also learn troubleshooting techniques and to recognize and solve various extrusion problems. People involved in maintenance will learn proper maintenance procedures and how to set up preventive maintenance.
