Co Rotating Twin Screw Extruder Book Review:

Co-rotating screws and/or extruders are used in many branches of industry for producing, preparing and/or processing highly viscous materials. They find a wide variety of applications especially in the plastics, rubber and food industries. Co-rotating twin-screw machines usually have modular configurations and are thus quite flexible for adapting to changing tasks and material properties. Well-founded knowledge of machines, processes and material behavior are required in order to design twin-screw extruder for economically successful operations. This book provides basic engineering knowledge regarding twin-screw machines; it lists the most important machine-technical requirements and provides examples based on actual practice. Better understanding of the processes is emphasized as this is a prerequisite for optimizing twin-screw designs and operating them efficiently. Besides basic functions, such as compounding, the book focuses on: - the historical development of twin-screws - the geometry of the screw elements (fundamentals, basic patents, patents overview) - material properties and material behavior in the machine - fundamentals of feed behavior, pressure build-up and power input - examples of applications for various processing tasks - compounding: tasks, applications, processing zones - potential and limits of modeling - scaling-up various processes - machine design incl. drives and materials

The Technology of Extrusion Cooking Book Review:

Extrusion cooking is a specialist area of food technology because of the complexity of the interactive effects which are inherent in the system. General predictive modelling is very difficult because ingredients are diverse and can vary considerably. Modelling tends to be product specifi- new product development tends to be by experimental designs and good fortune. The emphasis of this book is on the latest and potential applications of twin screw extrusion in food production, specifically co-rotating inter meshing screw extruders. Of course, in order to develop products and maximise the extruder potential in terms of energy, product quality and output, an overall understanding of the material flow mechanism, barrel fill length and rheology is essential. The book aims to give explanations and general guidance with examples of screw design, configuration and operat ing parameters for a variety of product categories. It is also intended to help production operators diagnose the symptoms of particular problems such as temperature control, quality variation, raw material inconsistency, etc. For the product development technologist there is more than one way to make a similar product. For example, equipment manufacturers recom mend difficult methods for producing flaked corn. In addition, their machines may differ from each other in terms of screw design, power/ volume ratio, screw tip/barrel clearance, etc. , making scale-up more prob lematic.

Twin Screw Extruders Book Review:

Most books on plastics machinery include a preamble on the origin of such equipment, and some even discuss the origin of plastic itself, dating back to the early 1900s and such men as Leo Baekeland - the real founder of synthetic plastics. There seems therefore, little pur pose in reiterating what has been said before and going over the same ground so adequately covered in a number of books as well as the trade press. We are indebted to the author of this excellent treatise on twin-screw extruders for getting right down to the business at hand. The author makes mention of two pioneers - Roberto Colombo and Carlo Pasquetti - who were the first to develop twin-screw ex truders. It was my good fortune to follow the work of these pioneers, and, interestingly enough, the principles were so good that their work continues to be relevant even to the advanced and more sophisticated models so well defmed in this book.

Twin Screw Extrusion Book Review:

Twin screw extrusion has become an important part of polymer processing technology. Twin screw extruders are widely used for reactive, procesing, including both polymerization and grafting reactions, for compounding, blending, devolatilization, as well as for thermoplastic final shaping operations, particularly profile extrusion. The purpose of this book is to carefully describe each of these three types of machines and the historical development of their technologies. The book also provides insight into the efforts to model/simulate the flow characteristics of these machines and into the experimental studies of their machine characteristics. This book is unique in clearly distinguishing between the different types of twin screw extruders on the market and in reviewing their capabilities. It is the authors' primary intention to provide a balanced but in-depth overview of twin screw extrusion technology to chemists, engineers and technologists alike

Polymer Processing Book Review:

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.
