PLST2011 Extrusion Molding Processes I

This course is designed to introduce the student to extruder operation and control - Single Screw, this course teaches the fundamentals of single screw technology, including the knowledge needed to make informed decisions on the production floor. This course includes sheet extrusion technology used in conjunction with the nine lesson single screw extrusion program. Personnel in many functions from machine operators to process engineers will find the information in this course valuable to help make their work with the sheet extrusion process more efficient. This course utilizes an interactive training program using CD-ROM based (software). Set-up, operation and troubleshooting of several extrusion dies and down stream equipment will be emphasized. This course will cover the characteristics of hazardous wastes and its safe handling, storage, and disposal.
