Principles of Extruder Die Design

This course covers the theory and practice of designing dies for extrusion systems. The program reviews the importance of die conductance during the entire extrusion process and not only in shaping the product; the die design process, along with the calculation of die conductance is explained; issues such as product curvature, co-extrusion dies, cutter and knife design, and the effect of die-plate wear are all considered. This course is relevant to the production of all types of extruded products including expanded snacks, breakfast cereals, pastas and third generation snack pellets, pet foods and aquafeeds.
