A surge of new molding technologies is transforming plastics processing and material forms to the highly efficient, integrated manufacturing that will set industry standards in the early years of this century. This book is a survey of these technologies, putting them into context and accentuating opportunities. The relations among these technologies are analyzed in terms of products, materials, processing, and geometry.

Engineers and technicians at manufacturing companies in the plastics industry that employ injection molding technology processes will want to have this reference in their library.
