Plastic Part Design

Plastic Part Design provides part designers with an understanding of the plastic part design process. This extensive, interactive online training program also addresses many of the factors and concerns associated with part design.

Dr. Robert Malloy, a respected author and professor at the University of Massachusetts, Lowell, developed these comprehensive courses.
