Mold Design & Moldmaking

This comprehensive 9-part online training program was created with help from many of the world's leading tool manufacturers and suppliers and is intended for tool designers, mold makers, engineers, part designers, and anyone involved in the tool procurement process.

The Mold Design and Moldmaking Series familiarizes participants with the different types of injection molds, contemporary machining methods, and many of the available mold components. This course also provides the participant with a tool design methodology and a sample mold specification guide for reference.
