Course overview

In modern plastics manufacturing, production inefficiencies, quality issues, and material waste can quickly erode profitability. This course is designed to help you take control of the extrusion process, make informed decisions, and minimise costly errors.

Delivered in the classroom by industry experts, Exploring Plastics Extrusion provides a practical understanding of how to optimise single screw extrusion - from material behaviour and machine operation to downstream processing.

The course concentrates on the single screw extrusion process, with supporting modules covering compounding, rheology, and key application areas such as pipe, film, sheet, cable, and PVC profiles. Participants will gain the insight needed to troubleshoot effectively, improve consistency, and enhance overall process efficiency.

Learning outcomes

By the end of this course, you will be able to:
  • Spot and solve common extrusion faults before they escalate into downtime
  • Improve product quality and consistency across runs
  • Scale up R&D projects with confidence
  • Make informed choices on equipment purchases
  • Improve communication with suppliers, customers, and internal teams
  • Understand how different polymers behave during extrusion - and why

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
  • Understand the influence of rheology 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.
Troubleshooting 
  • Fault finding and practical solutions to common problems including:
  • Probable causes of surging, melt fracture, etc.
  • Difficulties encountered in handling rework, materials, feeding systems etc.

Who should attend

This course is ideal for professionals involved in the processing, quality control or technical management of extrusion operations.

It will be particularly valuable for:

  • Process and production engineers who want to optimise extrusion performance and troubleshoot issues effectively.
  • Technical managers and quality personnel responsible for ensuring consistent product standards and process reliability.
  • Customer and technical service staff who need a deeper understanding of extrusion processes to support clients and resolve technical queries.
  • Sales and purchasing professionals involved in specifying, selling or buying extrusion equipment and materials.
