Available in PDF, EPUB and Kindle. Book excerpt: The use of computers to numerically analyse polymer processing was first reported as for back as the 1950's, and the first commercial software became available around 20 years ago. Much research has been carried out since that time, and this report aims to summarise contemporary trends in both commercial and academic research and development. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.
Download or read book Design Formulas for Plastics Engineers written by Natti S. Rao and published by . This book was released on 2004 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although designing machines and dies for plastics processing is routinely done with the help of computer modeling and design programs, the results don't always hold up in industrial application. Therefore, it is essential for the designer to have an understanding of the underlying mathematical concepts and their limitations when working with these programs and/or trying to improve their output. This book presents a summary of the most important formulas and their applications to solve design and processing problems with plastics materials. Numerous practical examples guide the reader step-by-step through the computational routine of designing polymer machinery. The approach is unassuming and very practical to enable every engineer to apply these concepts in their daily work and improve their equipment and stabilize their processes. Contents: - Formulas of Rheology - Thermodynamic Properties - Formulas of Heat Transfer - Designing Plastics Parts - Designing Extrusion Equipment - Designing Injection Molding Equipment.

Download or read book Design of Extrusion Forming Tools written by Olga Carneiro and published by Smithers Rapra. This book was released on 2012-12-19 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of extrusion forming tools (dies and calibrators) is a difficult task usually performed by the employment of experimental trial-and-error procedures, which can hinder the performance and cost of the tools, may increase the time to market of new extruded products and limit their complexity.This book provides detailed information on the design of extrusion forming tools. It describes the main problems to be faced when designing dies and calibrators, the most relevant polymer properties to be considered in the design process, the specific problems related to several types of conventional extrusion dies, and recent developments on the design of special dies and process modeling. It is an updated and unique book on the subject, where each chapter is prepared by internationally recognized experts. Having in mind its nature, it is expected to become a useful reference book for higher education students (both undergraduate and graduate ones), teachers, researchers and engineers active in the extrusion industry.

This book was released on 2017-11-06 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Die Design for Extrusion of Plastic Tubes and Pipes" covers this topic from a uniquely practical perspective. The content draws on the author's over 50 years of experience in the plastics processing industry, most recently as head of the successful extrusion die manufacturing company he established in 1995. His approach is oriented toward solving production problems at the design stage using computer aided techniques for design and simulation of the plastic flow. The book provides a step-by-step guide to extrusion die design, with worked examples to illustrate problem solving. It is shown how important melt flow variables (e.g., pressure drop, shear stress, shear rate, temperature variations, and distribution variations, etc.) of key materials are determined using FEM software. The detailed drawings of complete dies for various applications that are provided constitute a rare and valuable resource. Both mono- and multilayer pipes are covered. Using the proven methods and examples from this book, the reader is well-equipped to understand dies for successful manufacture of tubes and pipes of many types.

Download or read book Principles of Polymer Processing written by Zehev Tadmor and published by John Wiley & Sons. This book was released on 2013-12-02 with total page 1004 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thoroughly revised edition of the classic text on polymer processing The Second Edition brings the classic text on polymer processing thoroughly up to date with the latest fundamental developments in polymer processing, while retaining the critically acclaimed approach of the First Edition. Readers are provided with the complete panorama of polymer processing, starting with fundamental concepts through the latest current industry practices and future directions. All the chapters have been revised and updated, and four new chapters have been added to introduce the latest developments. Readers familiar with the First Edition will discover a host of new material, including: * Blend and alloy microstructuring * Twin screw-based melting and chaotic mixing mechanisms * Reactive processing * Devolatilization--theory, mechanisms, and industrial practice * Compounding--theory and industrial practice * The increasingly important role of computational fluid mechanics * A systematic approach to machine configuration design The Second Edition expands on the unique approach that distinguishes it from comparative texts. Rather than focus on specific processing methods, the authors assert that polymers have a similar experience in any processing machine and that these experiences can be described by a set of elementary processing steps that prepare the polymer for any of the shaping methods. On the other hand, the authors do emphasize the unique features of particular polymer processing methods and machines, including the particular elementary step and shaping mechanisms and geometrical solutions. Replete with problem sets and a solutions manual for instructors, this textbook is recommended for undergraduate and graduate students in chemical engineering and polymer and materials engineering and science. It will also prove invaluable for industry professionals as a fundamental polymer processing analysis and synthesis reference.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamental concepts coupled with practical, step-by-step guidance With its emphasis on core principles, this text equips readers with the skills and knowledge to design the many processes needed to safely and successfully manufacture thermoplastic parts. The first half of the text sets forth the general theory and concepts underlying polymer processing, such as the viscoelastic response of polymeric fluids and diffusion and mass transfer. Next, the text explores specific practical aspects of polymer processing, including mixing, extrusion dies, and post-die processing. By addressing a broad range of design issues and methods, the authors demonstrate how to solve most common processing problems. This Second Edition of the highly acclaimed Polymer Processing has been thoroughly updated to reflect current polymer processing issues and practices. New areas of coverage include: Micro-injection molding to produce objects weighing a fraction of a gram, such as miniature gears and biomedical devices New chapter dedicated to the recycling of thermoplastics and the processing of renewable polymers Life-cycle assessment, a systematic method for determining whether recycling is appropriate and which form of recycling is optimal Rheology of polymers containing fibers Chapters feature problem sets, enabling readers to assess and reinforce their knowledge as they progress through the text. There are also special design problems throughout the text that reflect real-world polymer processing issues. A companion website features numerical subroutines as well as guidance for using MATLAB®, IMSL®, and Excel to solve the sample problems from the text. By providing both underlying theory and practical step-by-step guidance, Polymer Processing is recommended for students in chemical, mechanical, materials, and polymer engineering.
