Processing with Electric Molding Machines

This training provides learners with in-depth processing information for making appropriate and cost-effective decisions when working with electric injection molding machines.

Using standard industry terms and practices, with an emphasis on safety, this two-part training series will enhance the knowledge base of all production personnel involved with electric injection molding machines.

Processing with electric injection molding machines will identify several differences between hydraulic molding machines and all electric molding machines. Users will also learn how to optimize a given process running on an electric molding machine so they can take advantage of those differences. Topics include closed-loop process controls, hydraulic verses electric machine controls, and optimization strategies for various processes.
