Our Plastic Part Design Series provides part designers with an understanding of the plastic part design process. This extensive interactive training course 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 interactive training programs.
