This book offers essential background knowledge for understanding the expansive field of polymer processing and the innovative technologies shaping the plastics industry in the 21st Century. It merges practical engineering concepts with realistic modeling of polymer processes, structured into three informative sections. Aimed at newcomers to the plastics manufacturing sector and students in introductory polymer processing courses, it also serves as a valuable resource for practicing engineers. The text assists in selecting processes, identifying critical parameters during initial design phases, and optimizing processes. Throughout, practical examples illustrate fundamental concepts. The first section introduces polymeric materials, covering their mechanical behavior and melt rheology. The second section delves into major polymer processing methods, including extrusion, mixing, injection molding, thermoforming, blow molding, and film blowing. The final section equips engineers with tools for solving polymer processing models, encompassing dimensional analysis, scaling, and transport phenomena in polymer processing. This comprehensive approach ensures readers gain a solid foundation in both theory and application, making it an indispensable guide for anyone involved in the field.

This unified approach to polymer materials science is divided in three major sections: Basic Principles - covering historical background, basic material properties, molecular structure, and thermal properties of polymers. Influence of Processing on Properties - tying processing and design by discussing rheology of polymer melts, mixing and processing, the development of anisotropy, and solidification processes. Engineering Design Properties - covering the different properties that need to be considered when designing a polymer component - from mechanical properties to failure mechanisms, electrical properties, acoustic properties, and permeability of polymers. A new chapter introducing polymers from a historical perspective not only makes the topic less dry, but also sheds light on the role polymers played, for better and worse, in shaping today's industrial world. The first edition was praised for the vast number of graphs and data that can be used as a reference. A new table in the appendix containing material property graphs for several polymers further strengthens this attribute. The most important change made to this edition is the introduction of real-world examples and a variety of problems at the end of each chapter.

Based on lecture notes from a five-week polymer processing laboratory course taught at the University of Wisconsin-Madison, this text provides background on polymer processing for engineering students and practicing engineers. According to the author, „It is written at two levels: an introductory level for students and engineers unfamiliar with polymer processing, and a more advanced level for more in-depth material.“ The more advanced level is „shaded“ to distinguish it from the introductory level. The book presents enough information so that, with their fluids and heat transfer background, engineers can understand and solve polymer processing problems. Contents: Introduction to Polymers. Mechanical Behavior of Polymers. Rheology of Polymer Melts. Extrusion. Mixing. Injection Molding. Secondary Shaping. Other Important Polymer Processes. Appendices-Extrusion Laboratory. Injection Molding Laboratory. Blow Molding Laboratory. Thermoforming Laboratory. Film Blowing Laboratory. Transport Phenomena Equations. Properties Table. Subject Index. Biography.

This book introduces engineering properties of polymeric materials to students and engineers from a material science perspective. It begins with a presentation of the chemistry of polymers, followed by an extensive description of their non-mechanical properties. The rheology of polymer melts is covered. The solidification processes of thermoplastic and thermosetting materials are discussed. Examples illustrate the effects of processing conditions on the dimensional integrity and properties of plastic components. This is followed by a presentation of the mechanical behavior of polymer parts, with an emphasis on creep, relaxation, fatigue and viscoelasticity. Partial Contents: Principles. Structure of Polymers. Thermal Properties. Influence of Processing. Rheology of Polymer Melts. Mixing. Anisotropy Developing During Processing. Solidification. Engineering Design. Mechanical Behavior. Failure. Electrical and Optical Properties. Permeability. Acoustic Properties.

Die Eigenschaften und die Leistungsfähigkeit eines Kunststoffteils sind dadurch charakterisiert, dass das Materialverhalten stark durch das Zusammenspiel vieler einwirkender Faktoren beeinflusst wird. Die Herstellung eines Kunststoffteils beginnt mit der Werkstoffauswahl in den frühen Phasen der Formteilkonstruktion. Bei der Konstruktion und der Herstellung von Kunststoffprodukten muss deshalb berücksichtigt werden, dass sich Materialeigenschaften, Verarbeitungsverfahren und Konstruktionsmerkmale gegenseitig beeinflussen und nicht getrennt betrachtet werden koennen. Dieses Buch behandelt sowohl die Werkstoffkunde der Kunststoffe, als auch die relevanten Verarbeitunsprozesse. Der zweite Teil des Buches behandelt die Modellierung mit Hilfe von analytischen Methoden, während im letzten Teil die numerischen Konzepte zur Simulation kunststofftechnischer Prozesse behandelt werden. Die Diskussion produktspezifischer Aspekte ist nicht Gegenstand dieses Buches, vielmehr sollen die Techniken erläutert werden, die zur Modellierung und Simulation von Verfahren in der kunststofftechnischen Praxis eingesetzt werden.
