Course Description

Course Content Densification, Mixing, Compounding, Reinforcement, Reactive Processing, or the production of a particular shape. Extrusion Theory - Feeding, Melting, and Pumping processes in single and twin screw machines, and the energy balance of the process. Rheology- its influence on the extrusion process. Extrusion Design - Aspects of design, choice and purchase of equipment. Twin Screw Extrusion - Different types of twin screw, their uses and compounding optimisation Mixing - Various mixing techniques exist, add on mixing heads, barrier screws and modular kneading elements. Scale-up - Sizing of a machine from laboratory trials, scale-up, and choice of equipment. Downstream- Compound, pipe, film, sheet, cable sheathing, profiles. Trouble shooting - Fault finding, practical solutions to common problems, i.e. probable causes of surging, melt fracture, etc., difficulties encountered in handling rework Materials, feeding systems, etc. Practical Demonstration Practical demonstrations will be used to illustrate aspects of the course. Attendees will learn: The Basic Extrusion Process - What are we aiming to achieve? The various elements of the extrusion process The theory behind feeding, melting and pumping Critical aspects of design, choice and purchase of equipment The essential differences between single and twin screw extrusion Important elements of mixing in theory and practice How to scale up both single and twin screw extrusion processes How different end products are produced An approach to trouble shooting with solutions to common problems
