Who is this course for
This course is suitable for
- Extrusion Operators
- Technicians
- Engineers who are currently working in the extrusion industry
- Or who are planning to work in extrusion and who have had no formal extrusion training,
- Or anyone who needs an understanding of the extrusion process.
Learning outcomes
At the end of this course attendees will be able toc
- Explain the safety considerations associated with extrusion tooling including heat electrical and chemical substance hazards
- Explain how extruded component size can be controlled by process parameters such as air pressures, vacuum pressure, screw speed and haul off speed.
- Explain basic Statistical Process Control (SPC) concepts such as average, standard deviation, range, process capability (Cp) and mean shift (Cpl0).
- Create control charts to record drawing dimensions and monitor the extrusion process.
- Remove and clean a screw from a single screw extruder
- Remove a die from an extruder without compromising personal safety or risking tooling damage.
- Handle extrusion die tooling to include labelling, assembly, disassembly, and damage avoidance using protective storage.
- Demonstrate the effects on extruded component size of changes in process parameters such as air pressure, vacuum pressure, screw speed and haul off speed.
- Perform extrusion tooling assembly giving due consideration to assembly sequence, tooling selection, tooling condition, torque levels, details of tool sealing surfaces and surfaces in contact with plastic melt.
- Interpret production drawings to produce plastic extrusion components in accordance with design specifications
