  • Course: Injection Molding Process III
  • Course #: PLST2143
  • Total Credits: 4

Course Description

This course is a continuation of Injection Molding II and is designed to introduce the student to injection molded part problems and solutions. Part defects are described and analyzed to show how each develops. Topics also include an explanation of the cause and effect method of problem analysis used in analyzing and solving all types of production problems. This course utilizes Paulson Training Programs' interactive CD-ROM based software. Content includes set-up, operation and troubleshooting of several types of Injection Molding Machines, Molds and Materials to produce quality plastics molded parts. Optimization of setting and started the mold will be emphasized. This course will cover the characteristics of hazardous wastes and its safe handling, storage, and disposal.
