Course overview
This course will help you better understand the whole extrusion process, helping you to optimize your processes, troubleshoot and avoid problems.
Please note: This course will concentrate on the single screw extrusion process, both within the extruder and downstream. Areas such as compounding (single and twin screw) rheology, pipe extrusion, film, sheet, cable and PVC profiles will be addressed in short modules.

Course content
- The Basic Extrusion Process: What are we trying to achieve? 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.
Who will benefit?
- Process/production engineers
- Technical managers
- Personnel involved in quality control
- Customer/technical services
- Those responsible for selling or purchasing extrusion equipment
