Complete Injection Molding

 Returning Spring 2015!
Time: 8:00 AM - 4:00 PM
Location: Akron Polymer Training Center, Akron, OH 44325-5404
Cost: $1,400 USD
CEU's: 1.9
Instructor: John Hickman

Course Overview

This 2 1/2 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 instructor will discuss scientific molding including pressure and thermal transducers for maximizing control. 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 to formulate possible solutions. Concepts discussed in the classroom will be reinforced with "hands-on" activities in the Akron Polymer Training Center's laboratory.

Please note: 8:00 a.m. - 4:00 p.m. on first two days of class; 8:00 a.m. - 12:00 p.m. on third day of class.
