Energy in Plastics Technology Theory and Practice

"Energy in Plastics Technology" provides, unlike any other book, the necessary fundamentals for dealing with thermotechnical issues in the processing of plastics, leading to efficient, robust, reliable, economical, and environmentally friendly processes for high-quality products. Included are the following subject areas: - Thermodynamics (main theorems, treatment of chemical transformations); - Fluid mechanics including explanation of similarity theory; - Heat transfer (free and forced convection, steady-state and unsteady-state heat conduction, some aspects of heat transfer by radiation); - Thermal and caloric state behavior, deformation and flow behavior of plastics (rheology). The fundamentals provided are applied - in exemplary calculation examples - to problems relevant to practice in the most important processing and forming methods: heating and cooling processes of molds, extrusion, blow molding, injection molding, pressing of thermosets and thermoplastics, calendering, FRP forming, foaming, casting, additive processes, forming processes, welding, coating processes. The focus is on energy consumption in the form of heat and work (economic and ecological aspects) as well as the resulting temperatures (quality aspect). The book is aimed at engineers and students working in plastics technology as well as technicians and plastics technologists.
