Molding the Impossible: the NYPRO/Vistakon Disposable Contact Lens Project

by Clayton M. Christensen


NYPRO, Inc., one of the world's leading manufacturers of plastic injection-molded products, is asked by the Vistakon Division of Johnson & Johnson to manufacture molds that Vistakon will use to produce disposable contact lenses. The required dimensional tolerances for NYPRO's molds are 10 times tighter than it has ever achieved before. The case describes how engineering teams in these two companies attempt to work together to develop a capable process for making molds and lenses.
