Complete Injection Molding
Course Number: 170-0970
Date: 07/27/2022 - 07/29/2022
Time: 8:00 AM - 4:00 PM
Location: 225 E Mill St, Akron, OH 44325
Akron Polymer Training Center
Cost: $1,500.00 USD
Instructor: Mr. Mark McGinnis
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 (1/2 day).
Who Should Attend: This course is designed for plastics professionals including engineers, managers, quality assurance, manufacturing and sales personnel desiring to build upon a solid foundation in the area of injection molding.
"Real world examples helped illustrate the topics. Overall, a great experience! Will definitely recommend to others."
- Debbie Richie, Strategic Sourcing Specialist, Invacare Corporation
