Purpose & Overview
The attendee learns the steps of designing and building injection molds and how and why a mold is designed. State-of-the-art mold design concepts are taught with the use of a high-quality powerpoint presentation using real-world examples.

Who should attend?
The seminar is designed to provide basic technical knowledge of the injection mold design and the building process for product, project, manufacturing, plastic and tool engineers as well as sales, technical and management personnel involved with molds and molding.
