EXTRUDER OPERATION AND CONTROL – SINGLE SCREW
Goals of this Course:
This popular online training series uses 3D animation technology to teach the fundamentals of single screw technology, including parts and operation, plastics used for extrusion, extruder controls, safety procedures, using additives, troubleshooting, and more. It’s the foundational knowledge plastics pros need to understand before continuing learning with a specialized course geared towards their role. We meet you where you are: fully online means attendees can start and stop the lessons as needed and learn anywhere with a high-speed internet connection.
- Engaging for all levels, from beginners to advanced technicians
- Prepares learners for other Paulson training extrusion courses topics such as twin screw extrusion, sheet extrusion, and extrusion blow molding.
Dive into the latest technology of the single screw extrusion process – from start-up to shutdown. Learn about extrusion machinery, plastic behavior, and how to maximize the productivity and efficiency of the extruder. Through eleven lessons, you’ll learn to optimize the extrusion process, quickly solve problems, and develop advanced troubleshooting skills.
Extruder Operation and Control – Single Screw is the most in-depth single screw extrusion course series on the market with 11 lessons and 20+ hours of training.
This recently updated course includes:
- Updated with modern, 3D visuals
- New learning modules
- Footage from several live molding facilities
- Automatic record keeping
Lesson 1: The Single Screw Extruder: History and Introduction
This lesson starts with a brief look at the origins of the plastics industry. It then continues with a deep dive into the common parts and operation of a single screw extruder.
Lesson 2: The Single Screw Extruder: Parts and Operation
A continued exploration of the common parts and operation of a single screw extruder with a focus on the screw and barrel.
Lesson 3: Introduction to Plastic Raw Materials
Explains how plastics are made (polymerization) and the major variations in plastics (thermoplastic vs. thermoset). Looks at the molecular structure of the different plastics and how this affects their processing and the physical properties of the products made from them.
Lesson 4: Plastic Behavior and the Effects of Additives
This lesson focuses on how additives affect the processing of plastic materials and looks at the problems caused by moisture in/on the raw material.
Lesson 5: The Effects of Temperature, Pressure, and Flow
This lesson teaches the characteristics and practical effects of plastic flow in extrusion. Topics include how and why orientation occurs with plastic flow, the interrelationship between flow and viscosity in a non-Newtonian fluid (plastics are non-Newtonian), how viscosity is affected by temperature, pressure, and molecular length, and how plastic flow behavior is measured.
Lesson 6: General Processing Variables and Extruder Controls
A look at the material variables and how they affect the extrusion process.
Describes variables within the extrusion process and discusses how these variables and control settings affect the process from the hopper through the feed zone of the extruder.
Lesson 7: Optimizing Hopper & Feed Zones
A detailed look at controlling the material flow from the hopper through the feed section of the extruder.
Lesson 8: Optimizing Compression and Metering Zones, Methods of Pressure Control
A detailed look at controlling the material flow through the compression and metering zones of the extruder. Controls for the adapter zone and gear pump are also discussed.
Lesson 9: Safety, Pre-Start and Start-Up Procedures
This lesson teaches safety procedures in the extrusion plants and practical, hands-on, pre-start and start-up procedures.
Lesson 10: Steady-State Operation, Shutdown and Maintenance Procedures
Discusses steady-state extrusion operation and typical shut down procedures for leaving the extruder full of plastic, running the barrel dry, and purging.
Lesson 11: Single Screw Extruder Troubleshooting
This lesson teaches the basic guidelines and fundamental steps to follow for successful troubleshooting of extrusion processing problems. Many of the most common extrusion processing problems are analyzed, and recommendations given.
