Purpose & Overview
This seminar covers the principles of the injection molding process and provides insights required to understand the connection between flows in the barrel and cavity, behavior of different polymers to process demands and ultimate part properties. Novel process features and unique products are covered along with many case studies to illustrate the commercial implementation of advanced design concepts for new product opportunities.

Who Should Attend
All people involved in injection molding will benefit from this course, especially process engineers, mold and product designers and other personnel with direct responsibility for quality. Familiarity with the process is desirable, but not a requirement, since molding principles and basic concepts are introduced and developed on a general process foundation.
