International Seminars |
|
These seminars have been
developed specifically for plastics industry professionals (managers,
designers, engineers) to gain a clear understanding of the current
state of the art in simulation for plastics processing and what it
can do to improve your company’s efficiency. John Perdikoulias
is the vice president of Compuplast, a company that provides advanced
CAE tools and services to the polymer processing industry. He is a
Licensed Professional Engineer with two graduate degrees in the area
of polymer extrusion and coextrusion. He also has more than 15 years
of "hands on" experience in polymer processing equipment
design and product development. His background results in a seminar
that provides the required balance of theory and practical information
for the attendees to gain a truly useful understanding of CAE analysis.
Extrusion Process Analysis, Design and Troubleshooting with CAE.
8:30 a.m. - 11:30 a.m., Wednesday March 24
Cost: $149 or any two Compuplast seminars for $199
This seminar will give attendees new insight and understanding into
the behavior of polymer melt within the extrusion equipment. With
the aid of unique visualization experiments on special extruders and
dies and advanced CAE simulation software (FLOW 2000), the attendees
will gain a proper understanding of the extrusion process and learn
what are the important factors that need to be considered for optimization.
Practical case studies will be used to demonstrate the application
of improved process understanding towards equipment design and troubleshooting.
The relationship between material characteristics and process limitations
is also a major theme.
Who Should Attend: This course is intended for process engineers,
plant managers, screw and die designers and anyone else interested
in learning how to optimize the extrusion process and gain a better
understand of the process.
The topics presented include....

How the extruder feeds, melts and
pumps.
Direction visualization of extrusion process with special glass
window extruder.
How to characterize materials properly and why Melt Index is
not sufficient.
The difference between smooth bore and grooved feed extruders.
The difference between conventional and barrier screws.
How to select which type of extruder/screw combination is best
for your process and material.
How to estimate extruder efficiency
How to get the "true" melt temperature.
The most common problems associated with breaker plates and
screen changers.
How to size an extruder adaptor properly.
The principles behind extrusion die design.
Flow visualization in spiral dies

Some coextrusion problems and their solution with CAE analysis. |
Applied CAE for Profile Die Design
1 p.m. - 4 p.m., Wednesday March 24
Cost: $149 or any two Compuplast seminars for $199
This presentation will provide the attendees with the basic knowledge
required to understand how computer aided engineering (CAE) analysis
can be used for Profile Die design. Several practical examples will
be used to show how CAE analysis is performed and what are the current
benefits and limitations. Attendees will also be introduced to the
new FLOW 2000, Profile Die simulation software from Compuplast and
shown how it can significantly reduce the time and cost for developing
a complex profile die.
Who Should Attend: This course is intended for plant managers, engineers,
designers or anyone involved with profile extrusion or responsible
for profile die design and reduced development costs.
The topics will include.

Material characterization
and shear viscosity
Why traditional flow balancing techniques are inefficient
The Cross Flow Minimization Method ™ of die design
Determining the maxim extrusion rate and process limitations
Cooling analysis for Calibrator Design |
CAE for Thermoforming and Blow Molding
8:30 a.m. - 11:30 a.m., Thursday March 25
Cost: $149 or any two Compuplast seminars for $199
This presentation will provide the attendees with the basic knowledge
required to understand how computer aided engineering (CAE) analysis
can be used to help reduce development costs in blow molding or thermoforming.
Several practical examples will be used to show how CAE analysis is
performed and what benefits it can provide towards cost reduction
during product and mold development. Attendees will also be introduced
to the new B-SIM, blow molding simulation software and T-SIM thermoforming
simulation software from Accuform.
Who Should Attend: This course is intended for plant managers, engineers,
designers or anyone responsible for the design or the production of
blow molded or thermoformed parts and molds.
The topics will include.

NOTE: The following planned seminar
has been cancelled (March 18, 2004).
Advanced Injection Molding Troubleshooting and Simulation Seminar
by Paulson Training
8:30 a.m. - 3:30 p.m., Thursday March 25
Cost: $199
This dynamic 1-day seminar led by Umberto
F. Catignani is the most engaging and practical injection molding
seminar in the marketplace today. The use of seasoned instructors,
eye-catching 3-D video and graphics that detail the inner workings
of the process, and Paulson’s unique injection molding simulation
software, SimTech make it possible to understand and problem solve
the injection molding process like never before.
Attendees are assumed to have practical knowledge and experience
in operating an injection molding machine. This seminar will explain
the “why” of how a defect is caused and the “how”
of all the ways to fix it. The seminar will deepen your understanding
of how the machine controls affect specific part properties. You’ll
learn to analyze and predict the result of process changes before
they’re made. Through the use of SimTech molding simulation
software, attendee’s will be able to practice mold dozens
of real-world scenario’s that will form a foundation for real
understanding of the injection molding process.
Outline of Seminar Content:
| • |
Review of molding
machine operating controls and their function (attendees should
be experienced in this area) |
| • |
Plastic flow behavior as it relates
to the injection molding process. Understanding the process
from the plastic’s point of view is mandatory for accurate
troubleshooting. This includes:
•
•
•
•
• |
Plastic temperature
Plastic pressure
Plastic flow rate
Plastic cooling rate
Plastic viscosity |
|
| • |
The Injection Molding Process is
examined for the exact purpose and operation of each machine
control as it relates to:

How each control affects the machine and the plastic |
|
| • |
Viewing Injection Molding as a
heat transfer process – not a forming process.
•
