Course Overview: This two-day course covers injection molding processes from machine and tooling to the production of high quality parts. Advanced injection molding principles that will be presented include tooling/design, plastic material behavior and avoiding molding defects. The course focuses on the development of troubleshooting skills and the specific needs of each individual class member. All students are welcome to bring samples for discussion for formulating possible solutions. Concepts discussed in the classroom will be reinforced with "hands-on" activities in the Akron Polymer Training Center's laboratory.
