Overview
This seminar has been developed to help train
extrusion process personnel and equipment designers on how the polymer
properties (rheological and thermal) interact with the equipment and
process conditions in the extrusion process and how this relates to the
final product. Upon completing this course, the attendees will have a good
understanding of practical rheology and what can (and cannot) be applied
to the quantitative study of an extrusion process. Explaining why
certain extrusion “phenomena” occur is a major overall theme during
this seminar, which is presented from an industrial point of view with
many “case-study” type examples. The availability of powerful CAE tools for extrusion is
rapidly changing extrusion equipment design from what once was an
intuitive craft into a science. The "Hands-On" portion of seminar will
have the attendees using a “Virtual Extrusion Laboratory” of
simulation software to simulate a wide variety of extrusion processes and
equipment. The effect of design variables, processing conditions and
material changes will be demonstrated with emphasis on process
optimization and troubleshooting.

Who Should
Attend
This course is intended for anyone or who is currently
(or training to become) responsible for the design or performance of an
extrusion process. Extrusion screw and die designers, process engineers,
technical service personnel, research and development personnel and
particularly, those responsible for troubleshooting extrusion processes
will obtain the most benefit from the information presented. The topics
that will be covered will be applicable to all areas of extrusion
including pipe and tubing, film and sheet, wire and cable coating, blow
molding, profile extrusion, etc. The attendees are urged to bring along
some of the extrusion problems that they are currently faced with and
would like to have addressed during the course.

What You Will Learn
This seminar will show attendees how to properly evaluate
and analyze extrusion equipment using sound engineering principles.
Process Engineers will learn how to properly analyze and troubleshoot
their equipment in order to optimize performance. Designers will learn
about the most important design criteria that should be used for extrusion
equipment. Attendees will also gain valuable "Hands-On"
experience with the most advanced set of CAE tools available for
extrusion.
The seminar will introduce practical rheology (polymer
flow behaviour) in a clear and straightforward manner as it applies to the
process operations that will be presented. The focus is on the rheological
characteristics of the polymers that are most important to the
understanding of the extrusion process and to the design of the equipment.
After this seminar, the attendees will be better qualified to select
materials and to differentiate between equipment design, which can be a
big benefit during future product development or equipment specification
and selection.
Some Comments from past short course participants:
"This course was so useful for my job. These are the
types of courses we need more of. This was money well spent."
"I believe this was the most interesting, well
organized, and valuable internal course I've had the pleasure of
attending. Thanks"
"Excellent instructor. Well-organized course."
"Very well organized, very practical. Better than the
previous Rheology course I took!"
"One of the best courses I have attended in years.
Application of Rheology was very practical in this course."
"I really enjoyed this course. It was very relevant
and provided a lot of useful information and insight. The speakers
were excellent!"
"Very good! I learned a lot about "real
world" applications of rheology for PE."
"Found course very useful, liked that it was very
application related (I.e. extruder, dies, screw) and that there
were many real world (practical) examples given. Presentation
slides were excellent. Windowed extruder slides very useful."

Day 1 Morning: Polymer Rheology
The attendees will learn about the most important
rheological measurements (such as shear viscosity), what they mean, how they
are obtained and, most importantly, how they affect the extrusion process.
Attendees will be shown how to use the CompuplastÒ
Materials module to fit viscosity data to models and then use the
data for calculations. The attendees will also be shown how to use the
CompuplastÒ ExtrusionCalculatorÔ
to perform many useful calculations and analyze and troubleshoot a wide
variety of extrusion equipment. |

Day 1 Afternoon: The Extruder
This part of the seminar will describe the functions and
the requirements of an extruder using both a combination of theory and
videos of experiments performed on glass window extruders. The main
principles of operation are reviewed and design parameters explained from
a CAE point of view.
Attendees will use the Virtual Extrusion LaboratoryÔ, Extruder
Module to simulate single screw extruders and see how operating speed and
material characteristics can affect the quality of the melt that is
produced by the extruder. They will also be shown how the
simulation can be used to analyze or troubleshoot existing screw designs
and extruder operating conditions or to evaluate new design proposals. |

|
|
Day 2 Morning: Mono-Layer Die Analysis and Design
This section of the course will focus on the requirements of
extrusion dies. Design parameters and criterion will be provided for a wide
variety of processes and materials. Topics will include flat die design,
spiral die design, pipe and tubing die design and coating applications The
attendees will be shown how to use the Virtual Extrusion LaboratoryÔ
, Flat Die Module for
analyzing flat dies commonly used to sheet and film production |
 |
|
Day
2 Afternoon: Mono-Layer Die Analysis and Design Continued
The attendees will continue with mono-layer die analysis
and design for annular. The various types of annular dies will be
presented with emphasis on the advantages and disadvantage of each
type. The attendees will be shown how to evaluate various types of
annular dies including spiral mandrel
type dies, commonly used for blown film, pipe and blow molding
applications, with the aid of the Virtual Extrusion LaboratoryÔ, Spiral Die Module. The
emphasis will again be on how to quantify the performance of these dies
and why good polymer distribution is not necessarily the best criteria to
use. Video presentations of visualization experiments will be used to help
explain the concepts.

|
Day 3 Morning: Profile Die Design
One of the most challenging aspects of extrusion is the efficient
design of profile dies. This part of the short course will focus on
explaining why profile dies appear to be difficult to design and offer a
solution to this problem. Compuplast has developed a unique approach to the
problem that has been proven to reduce most profile die development time by
at least 50%. The attendees will be shown the Compuplast® Cross Flow
Minimization Method Ô
for profile die design and how to apply the CFMMÔ
using the Virtual Extrusion LaboratoryÔ, Profile Die module. |
 |
| Day
3 Afternoon: Co-Extrusion Die Analysis and Design
The next topic in the course will be about coextrusion. An overview
of the most common problems associate with coextrusion flow fields will be
presented along with their possible solutions. The attendees will be given
some criteria and shown how the coextrusion flow fields can be analyzed
and optimized with the
CompuplastÒ ExtrusionCalculatorÔ
. The short course will conclude with a general discussion on
troubleshooting degradation and gels. This presentation will
re-enforce the concepts presented early in the course as well as provide
some guidelines for operating the equipment so as to minimize the
potential for polymer degradation.
The course should be finished by 4:00 pm pm |
