Specifying the proper feeder for your material handling system will ensure process performance levels are maintained to reduce material costs and reduce scrap; therefore improving process efficiency. During this webinar you will be introduced to different types of feeders and learn how each is applied to handle various material flow properties for each ingredient in a process.
The distinction between continuous and batch feeding will also be discussed and an explanation between volumetric and gravimetric control will be demonstrated.
After this webinar you will be able to ask the right questions when selecting a feeder for your next material handling application.
Primary topics (what the registrant will learn):
• Continuous vs. Batch Feeding
• Volumetric vs. Gravimetric Control
• PID Control Principle
• Basics of Weigh-Belt and Loss-In-Weight Feeding
• Volumetric Feeder Types
• Selecting the Right Feeder Type
• Available flow Aids
• Common Problems and Solutions to Improve Accuracy and Performance

Several factors should be considered when selecting a dilute phase pneumatic conveying system for plastics applications. Understanding the basics of pneumatic conveying can go a long way to ensure the best choices are made for an efficient and long lasting system. Two very important factors to consider are system pressure and product velocity. These two factors are strongly related but have independent functions. Paying careful attention to these can significantly extend the life of your pneumatic conveying system.
During this webinar you will learn the advantages and disadvantages of choosing a positive pressure system vs. a vacuum conveying system. We will present conveying techniques for bulk material delivery to storage, storage to process and finished product to storage packaging. We will also identity common problems that may occur with pneumatic conveying systems and present technical solutions. When choosing a supplier for your next conveying application, you will be certain you are asking the right questions.
• Basics of Dilute Phase Pneumatic Conveying Systems
• Pressure Drop Across a Conveying System
• Positive Pressure vs Vacuum
• Velocity in Pneumatic Systems
• Common Pneumatic Systems
• Common Problems and Solutions
Steve Broadbent, LSR/ELAST Project Engineer at ENGEL North America will present a comparison of different machine platforms in regards to processing LSR materials. A detailed description and explanation of recommended machine options specific to LSR processing will also be reviewed.
Primary topics
• Determine the correct machine platform based on market, molding environment and process
• Determine the correct clamp force based on part geometry and mold design
• Determine the correct screw diameter
• Importance of LSR specific options
There are lots of choices when it comes to granulators, but which one is right for you?
In this presentation, Jim Hoffman of Rapid Granulator will help to answer that question and many more on a brand neutral basis that you should be asking when looking for a granulator. It usually does not get as much attention as it deserves, and can cost you money in the long run.
Primary topics (what the registrant will learn):
- How to choose the right granulator for my needs.
- How can using a granulator help my company save money?
- Does rotor speed really matter?
- How do I know what horsepower is required?
- Why are there different cutting chamber styles?
More sophisticated tooling technologies are always evolving. One advancement that improves efficiency and speed is the hydraulic locking core pull cylinder.
By employing this method of actuating a core pull, molders can take advantage of smaller mold bases, and at the same time, reduce overall costs. This webinar will demonstrate how hydraulic locking core pull cylinders can actuate core pulls and mold slides in injection molds with much less design, machining, fitting and maintenance time than traditional slide assemblies.
Primary topics (what the registrant will learn):
• How do hydraulic locking core pull cylinders work?
• What are the advantages of using hydraulic locking core pull cylinders compared to other methods of actuating a core pull?
• What features, sizes and options are available?
• Tips for installation and operation
The seminar will explain the methodology to correctly choose the right screw size for the application at hand. Differences in the selection based on material processed will be explained in detail. A short side trip into plastic physics will provide the necessary explanation of the main differences between polymers and provide the foundation required to make the right selection.
Primary topics (what the registrant will learn):
- Proper screw size calculation, methods, formulas
- Understanding plastic density changes throughout the molding process
- Learn why residence time is not related to the "shot size" of the barrel
- Why percentages of barrel capacity is a rule of thumb at best
A single Central Dryer can dry several resins with different processing parameters in multiple hoppers. Learn the advantages of Central Drying and how integrating central conveying helps reduce material waste and improves quality/consistency. Payback scenarios for small and large Central Systems are included.
Primary Topics (what the registrant will learn):
• How Central Drying works.
• How Central Drying improves product consistency and productivity.
• How integration of Central Conveying reduces waste and can provide
validation/verification.
• Critical control requirements central systems.
• Payback and operational savings expectations.
A detailed and informative presentation explaining new molding processes that allow for ready-to-use part manufacturing in a single molding cell.
Instead of adding complexity and additional manufacturing steps offline and away from the molding cell, total cell integration improves the quality of the parts, while also reducing overall cost.
Processes to be discussed include:
Organomelt (use of composite structures combined with injection molding)
Functional Surfaces (integration of capacitive films and self-healing surfaces)
Primary topics (what the registrant will learn):
Benefits of in-mold technologies: improved part functionality, a different look, better quality, and reduced cost are a few to mention.
Beyond part cost: the multitude of cost benefits of in-mold technologies beyond part cost.
Reducing complexity: while the molding process usually increases in complexity with in-mold technologies, overall manufacturing process complexity is reduced, bringing about additional savings.
Learn why this technology works wonders today compared to when the basic principle was introduced 20 years ago.
If you are over-drying your material, especially nylons, you are destroying important physical properties and you are producing definitely spending too much for energy. If you are under-drying, there is a good chance that you are producing a high level of rejects. Simply using dew point, time and temperature does not tell you the moisture level of your pellets. Dew point only indicates the dryness of the process air – not the dryness of your material. Now, you can see in-line, real-time moisture content in % or parts/million and automatically correct the moisture content or divert material that does not meet your moisture specifications.
Primary Topics (what the registrant will learn):
• Traditional drying method – Dew Point, Time and Temperature.
• How under-drying and over-drying affects properties…and profits.
• Typical applications where moisture analysis is necessary.
• Standard methods of determining pellet moisture content.
• How moisture sensor technology has improved.
• New, in-line, real-time moisture analysis.
