About the Seminar
The seminar covers extrusion theory and teaches how theory can be applied to solve real extrusion problems and to optimize the process. Equipment issues and polymer properties will be covered. Extruder functions and quantitative analysis will be discussed in detail. This will be applied to screw and die design and to troubleshooting. Attendees will learn to calculate solids conveying rate, melting rate, pumping rate, diehead pressure, onset of melt fracture, temperature by viscous dissipation, etc. Attendees will be expected to answer a number of homework questions between the first and second day. These questions will be discussed the second day.
Who Should Attend this Seminar
This is designed for technical personnel who want to develop a better understanding of extrusion and learn to perform quantitative analyses and calculations. People that teach extrusion within their company will benefit from this seminar. Technical service personnel will be better equipped to advice customers and solve extrusion problems. This seminar is not recommended for people without an engineering degree.
