Prior extrusion books are based on barrel rotation physics—this is the first book that focuses on the actual physics of the process—screw rotation physics. In the first nine chapters, theories and math models are developed. Then, these models are used to solve actual commercial problems in the remainder of the book. Realistic case studies are presented that are unique in that they describe the problem as viewed by a typical plant engineer and provide the actual dimensions of the screws. Overall, there is not a book on the market with this level of detail and disclosure. The new knowledge in this book will be highly useful for production engineers, technical service engineers working with customers, consultants specializing in troubleshooting and process design, and process researchers and designers that are responsible for processes that running at maximum rates and maximum profitability.

Prof. Gregory A. Campbell is Professor Emeritus at Clarkson University, NY. He formerly directed a research group at GM Research and managed polymer fabrication at Mobil Chemical Research.
Dr. Mark Spalding is a Fellow in the Materials & Parts Processing Group at The Dow Chemical Company, where he has worked since 1985. He has performed fundamental research in single-screw extrusion, developed methods to measure resin physical properties that are important to polymer processing, developed numerous techniques to debug and increase the rates of extrusion lines, and has developed new mathematical models for extrusion simulation.
