What Our Participants Are Saying

What did you like most about the seminar?

"Labs helped to understand equipment and classes which provided information on how to find process setting parameters for different molding equipment."

"The combination of in-class and lab. It was great to talk about a subject and then see it in practice."

"Really appreciate working on actual equipment and seeing similarities and differences between models."

What are a few things you learned that you’ll bring back to your work?

"Mold filling and potential pitfalls, designing mold and troubleshooting different defects."

"Troubleshooting processes. Removing flash and short shots in day-to-day production."

"Anatomy of injection molding, defects caused by injection molding and optimization."

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.
