A handbook that answers over 1000 of the potential combinations of basic variables or problems that can occur from up-stream to down-stream equipment. Guidelines are provided for maximizing processing efficiency and operating at the lowest possible cost. It explains the various extrusion processes that produce different commodity and engineered plastic products. The text's practical approach provides for both the novice and experienced personnel, a methodology on extrusion advancements and trends. This leads to "streamlining" processing lines by anticipating problems that could occur, what causes them, how to eliminate them, and/or how to take corrective action. The content is arranged to provide a natural progression from simple to complex situations. It correlates materials, equipment, process controls, product requirements, and people. This text should be of interest to technical managers, technical staff academics, and students interested and involved in extrusion; scientists in both academia and industry working in related fields (eg design).
