Diagnostics Of Extrusion Processes

Troubleshooting extrusion problems is one of the most challenging tasks in extrusion operations, requiring a good understanding of the extrusion process and the material properties, good instrumentation, good analysis tools, and a systematic and logical approach. This book addresses all issues crucial in extrusion troubleshooting. Additionally, it includes industrial case studies, richly illustrated with photographs and photomicrographs, used to provide exemplary approaches to efficient problem analysis and problem solving. The interconnectivity between the different relevant knowledge areas such as materials engineering, processing technology, and product development is emphasized. This revised third edition comprises a very significant update, with a great deal of new content, especially focusing on additional case studies as well as new sections on collection and interpretation of extrusion process data, rotational rheometry, the smartphone, how screw design can affect extruder performance, melt temperature variation, recent research on automatic optimization of extruder barrel temperatures, process signal analysis using Fast Fourier Transform, among other topics.

A fresh view of the state-of-the-art, Advances in Food Extrusion Technology focuses on extruder selection, extrudate development, quality parameters, and troubleshooting in the 21st century extrusion process. In particular, the book:Introduces the history, nomenclature, and working principles of extrusion technologyPresents an overview of various t

In recent years the importance of extruded alloys has increased due to the decline in copper extrusion, increased use in structural applications, environmental impact and reduced energy consumption. There have also been huge technical advances. This text provides comprehensive coverage of the metallurgical, mathematical and practical features of the process.

This book presents concepts, methods and techniques to examine symptoms of faults and failures of structures, systems and components and to monitor functional performance and structural integrity. The book is organized in five parts. Part A introduces the scope and application of technical diagnostics and gives a comprehensive overview of the physics of failure. Part B presents all relevant methods and techniques for diagnostics and monitoring: from stress, strain, vibration analysis, nondestructive evaluation, thermography and industrial radiology to computed tomography and subsurface microstructural analysis. Part C cores the principles and concepts of technical failure analysis, illustrates case studies, and outlines machinery diagnostics with an emphasis on tribological systems. Part D describes the application of structural health monitoring and performance control to plants and the technical infrastructure, including buildings, bridges, pipelines, electric power stations, offshore wind structures, and railway systems. And finally, Part E is an excursion on diagnostics in arts and culture. The book integrates knowledge of basic sciences and engineering disciplines with contributions from research institutions, academe, and industry, written by internationally known experts from various parts of the world, including Europe, Canada, India, Japan, and USA.

Troubleshooting extrusion problems is one of the most challenging tasks for everyone involved in extrusion operations. It requires a good understanding of the extrusion process, knowledge of the material properties, good instrumentation, good analysis tools, and a systematic and logical approach.
