Overview

This seminar* is designed for those who are interested in an introductory course about the injection molding process. Topics include material behavior, the major components of the machine and the mold, part design, the steps of an injection molding cycle, a method to establish a reliable process, and ways to troubleshoot common molding defects. Time will be spent in the laboratory disassembling/assembling different types of molds, installing a mold (including the clamp setup), and establishing and troubleshooting a molding cycle.
