Course Title: Extrusion

10 Professional Development Hours/1.0 CEUs

Course Description: The Extrusion Course provides insight into the Extrusion process and the equipment required to complete an Extrusion process, including:

Dryer

Hopper

Extruder (components)

Screen changer

Static mixer (optional)

Die

Calibration unit

Puller and cutoff device

The program concludes with a discussion on inspection and measurement of the profile as it sets in its final geometry.

Overall Course Objectives:

Understand the components and processes involved in an extrusion operation.
Identify variables in the extrusion process and the effect these variable can have on production.
Explore extrusion equipment, in order to understand the mechanics of the extrusion process.
