This book provides the background needed to understand not only the wide field of polymer processing, but also the emerging technologies associated with the plastics industry in the 21st century. It combines practical engineering concepts with modeling of realistic polymer processes. Divided into three sections, it provides the reader with a solid knowledge base in polymer materials, polymer processing, and modeling.Understanding Polymer Processing is intended for the person who is entering the plastics manufacturing industry and as a textbook for students taking an introductory course in polymer processing. It also serves as a guide to the practicing engineer when choosing a process, determining important parameters and factors during the early stages of process design, and when optimizing such a process. Practical examples illustrating basic concepts are presented throughout the book.New in the third edition are chapters on data-driven modeling and physics-driven modeling, as well as new sections on manufacturing and dimentional analysis. In addition to a number of other smaller improvements and corrections throughout the book, bonus code downloads are also provided.Part I: Polymeric Materials: This section gives a general introduction to polymers, including mechanical behavior of polymers and melt rheology. Part II: Polymer Processing: The major polymer processes are introduced in this section, including extrusion, mixing, injection molding, thermoforming, blow molding, film blowing, and many others. Part III: Modeling: This last section delivers the tools to allow the engineer to solve back-of-the-envelope polymer processing models. It includes dimensional analysis and scaling, transport phenomena in polymer processing, and modeling polymer processes.

There are many books on composite material analysis, but most cover mainly continuous fiber materials, rather than those filled with discontinuous fibers, which are particularly attractive for large-volume and low-cost applications. This book provides the theoretical and practical background to design and use discontinuous fiber-reinforced polymer materials, with an emphasis on structural parts for the automotive industry. Moreover, the product of years of collaborative work between industry and academia is presented in an easy-to-use, comprehensive manner.The information provided makes it possible for someone with an engineering background to understand the micromechanics of discontinuous fiber-reinforced materials and, hence, analyze the structural performance of components designed with such materials. The book employs a practical approach to cover the key, unique capabilities that are critical for a successful structural analysis of discontinuous fiber-reinforced polymer structures:Process simulation to estimate the condition of fibers in the finished parts, i.e., fiber length, orientation, and concentrationCapability to measure micro structure, i.e., fiber length distribution, fiber orientation tensors, and fiber concentration, etc.Estimation of material properties in the part based on fiber condition, as well as environmental conditions such as temperatureA broad range of areas is included, such as joining and assembly.

The fifth edition of Plastics Handbook provides everything important there is to know about plastics, comprehensively compiled in a compact and well-organized format. From material properties to machines, processing, and applications, the user will find detailed information that allows the successful implementation of new materials and technologies.This concise, competent, modern reference not only explains the basic facts and interrelationships, but also serves as a practical guide for engineers to help them succeed in today's challenging, global industrial world. Searching for specific materials, trade names, properties, or any other information is particularly easy, because the reader also has free access to the electronic version of the book.The fifth edition is comprehensively updated throughout, with an new clearer layout and it is also now in colour.The contents include:Common Acronyms in Plastics TechnologyIntroduction (Economic Significance, Classification, Composition, Effects of Processing on Properties, Modifications of Plastic Materials)Material Properties and Testing MethodsPlastic Processing TechnologiesPlastic MaterialsAdditives, Fillers, and FibersMaterial Properties

This book is designed to provide a background in polymer rheology to both engineering students and practicing engineers. It is written at an intermediate level with sufficient technical information and practical examples to enable the reader to understand the interesting and complex rheological behavior of polymers, to make the right decisions regarding rheological testing methods, and to troubleshoot rheology related problems encountered in polymer processing. The organization of the book and the practical examples throughout make it an ideal textbook and reference source. Processors and raw material suppliers will find the information within particularly valuable. Rheology is a rapidly growing and industrially important field, playing a significant role not only in polymer processing, but also in food processing, coating and printing, and many other manufacturing processes.

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.

The injection molding industry has a new, up-to-date, comprehensive handbook. Serving engineers, professionals, and others involved in this important industry sector, the handbook thoroughly covers every detail of the machine and the process. This all-encompassing resource also includes the topics directly affecting the injection molding process, such as materials, process control, simulation, design, and troubleshooting. The handbook presents a well-rounded overview of the underlying theory and physics that control the common injection molding process variation, without losing the practical hands-on presentation used throughout. This important book was written by a specifically chosen group of authors with a wide range of experience and perspective on the injection molding process - authors who are leading practitioners and researchers both in industry and academia. Contents: Injection Molding Materials. Processing. Plasticating Unit. Clamping Unit. Mold Design. Materials Handling and Auxiliary Equipment. SPC in Injection Molding. Special Injection Molding Processes. Injection Molded Part Design. Simulation in Injection Molding. Process Trouble Shooting. Materials Trouble Shooting.

This book addresses traditional polymer processing as well as the emerging technologies associated with the plastics industry in the 21st century and combines engineering modeling aspects with computer simulation of realistic polymer processes. This book provides a polymer processing background to engineering students and practicing engineers. It is a three-part textbook written for a two-semester polymer processing series in mechanical and chemical engineering. The first and second part of the book are designed for a senior- to graduate-level course, introducing polymer processing, and the third part is for a graduate course on simulation in polymer processing. Throughout the book, many applications are presented in form of examples and illustrations. These also serve the practicing engineer as a guide when determining important parameters and factors during the design process or when optimizing a process. Examples are presented throughout the book, and problems and solutions are available.
