Extrusion 1 Machine Setting
Cost:
€995 (10% discount for Plastic Ireland members)
Inclusive of course manual, lunch and refreshments.
This course is a very practical introduction to extrusion, the major focus of the course is to practice the correct techniques to start and stop an extruder, set up correctly using the correct tooling, and avoid the common issues such as degradation, ovality, concentricity issues, leaks from the die head, etc.
COURSE CONTENT
Overview of Extrusion
Safety in extrusion – heat, pressure, electrical and material degradation issues.
Overview of the various parts of an extrusion line.
Mixing and shear heating
How to handle tooling safely
How to start up and shut down the machine
How to select the correct die and calibrator sizes to avoid oval tubing
How to select the correct barrel and cooling bath temperatures
How to select the correct filter packs/ breaker plates and where to use
Start-up and Shut-down Procedures
Correct procedure to shut down an extruder
Ensuring tooling is correctly cleaned and handled
Preventing tooling damage
Correct procedure to disassemble the die
Screw removal and cleaning procedure
Correct procedure to clean and reassemble the die
Correct die tightening procedure
Centring the die to achieve concentricity
How to get the wall thickness
Achieving product Specifications
Correct threading up procedure and points to watch for
How to check and adjust the product to achieve specification
Quality Control
The importance of quality control procedures
How to set up and record control charts
Sampling procedures and sample sizes
How to read control charts to check for product drifting out of specification
Troubleshooting
How to analyse a defect to find the cause
Understanding basic extrusion problems:
- Unstable melt/ Die flow problems
- Sharkskin/ Melt Fracture
- Gels - Degradation (heat/ mechanical)
For this training, we use the facilities of the CNMR centre.The centre has the following extrusion equipment:
Sheet Extrusion - Width<600mm - Thickness <700mm
Cast Film - Width <600mm - Thickness>30um
Pilot Blown Film - Layflat <50mm - Thickness 50 - 250um
Compounding - 50mm single screw - 19mm twin screw Tube & Profile
Where possible we restrict extrusion course numbers to just six places. Our courses can be run in-company if required, or we can modify any course to your needs.
FETAC (NCVA/ CETEFOP) certification is included in the course costs - The FETAC approved examination conducted at the end of the course counts as one credit towards our Vocational Certificate in Polymer Processing
Who Should Attend?
This course is suitable for Operators/ Technicians who have had no formal extrusion training, or anyone who needs an understanding of the extrusion process. No prior experience in this area is assumed.

*This programme is a FETAC component (minor) award, certified at Level 5 on the national framework of qualifications (www.nfq.ie ).
The assessment at the end of the programme, if successfully completed, will lead to one credit towards a major(compound) award, of which 8 credits are needed in total. Please see How to achieve a FETAC major award with FPT. Some of our programmes have assignments as part of the assessment which should be completed by the learner after the programme has finished. Full instructions, timelines and ongoing guidance will be given by the course tutor. Most assessments are completed during the programme and results will be made available to learners as soon as they have gone through our Quality Assurance procedures and final submission to FETAC.
