Single Screw Fundamentals for Design and Optimum Processing

This is a two-hour workshop per session, but we have an additional 30 minutes in the schedule in case questions go longer.

This workshop provides a comprehensive foundation in Single Screw Fundamentals for Design and Optimum Processing. Participants will begin with an introduction to the basic single screw extruder and its functional parts, learning to convert screw geometry into useful mathematical calculations.

The curriculum connects extrusion performance directly to material science, examining molecular weight and distribution , basic polymer bonds , and primary degradation mechanisms. A core focus is placed on rheology and how polymer viscosity and shear thinning influence the process. The course explores the distinct functional zones of the screw, including:

• Solids Conveying: Analysis of the current model and its predictive limitations.
• Melting Zone: A look at the current melting model and the role of components like barrier screws.
• Metering Section: Focus on meter section calculations and the effect of die pressure on temperature.
