EXTRUDER OPERATION AND CONTROL – SINGLE SCREW
Goals of this Course:
This program uses state-of-the art animation technology to teach the fundamentals of single screw technology, including parts and operation, plastics used for extrusion, extruder controls, safety procedures, troubleshooting and more.Course Description: 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 nine lessons, you’ll learn to optimize the extrusion process, quickly solve problems, and develop advanced troubleshooting skills.

Lesson 1: The Single Screw Extruder: Parts and Operation
Teaches extruder applications, the raw material forms used in extrusion, how plastic travels through the extruder and the parts of the extruder and how they operate.
Lesson 2: The Structure of Plastic Raw Materials
Explains how a plastic is made (polymerization), the difference between thermoplastic and thermoset, the effects of molecular weight and weight distribution, the structure of polymers, and the physical characteristics and processing requirements of amorphous and crystalline plastics.
Lesson 3: The Characteristics of Plastics for Extrusion
This explains copolymers and blends/alloys, the causes and effects of degradation, and the effects of additives on the plastic in the extrusion process.
Lesson 4: Effects of Pressure, Temperature 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 5: Optimizing Extruder Controls – Part 1
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. How plastic melts and flows in the extruder is also explained.
Lesson 6: Optimizing Extruder Controls – Part 2
This will explain the effects of extruder control settings on the plastic’s behavior as it travels through the compression and metering zones of the extruder. Controls for the adapter zone and gear pump are also discussed.
Lesson 7: Safety, Pre-Start and Start-Up Procedures
This teaches safety procedures in the extrusion plants and practical, hands-on, pre-start and start-up procedures.
Lesson 8: Steady-State Operation, Shutdown and Maintenance Procedures
This discusses steady-state extrusion operation, and typical shut down procedures for leaving the extruder full of plastic, running the barrel dry, and purging.
Lesson 9: 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.
