Special Injection Molding Techniquescovers several techniques used to create multicomponent products, hollow areas, and hard-soft combinations that cannot be produced with standard injection molding processes. It also includes information on the processing techniques of special materials, including foaming agents, bio-based materials, and thermosets.
The book describes the most industrially relevant special injection molding techniques, with a detailed focus on understanding the basics of each technique and its main mechanisms, i.e., temperature, mold filling, bonding, residual stresses, and material behavior, also providing an explanation of process routes and their variants, and discussions of the most influencing process parameters.
As special molding technologies have the potential to transform plastics processing to a highly-efficient, integrated type of manufacturing, this book provides a timely survey of these technologies, putting them into context, accentuating new opportunities, and giving relevant information on processing.Provides information about the basics needed for understanding several special injection molding techniques, including flow phenomena, bonding mechanisms, and thermal behaviorCovers the basics of each technique and its main mechanisms, i.e., temperature, mold filling, bonding, residual stresses, and material behaviorDiscusses the most relevant processing parameters for each injection molding techniquePresents a variety of techniques, including gas and water assisted injection molding, multi component injection molding, hybrid injection molding, injection molding of bio-based materials, and techniques for thermoset
Rubber Recycling is one of those rare books that has the potential to directly impact our ecological well-being. The editors of this important volume have filled a void in technological responsibility by bringing together a group of international experts who, using substantial research evidence, prove that the utilization of recycled rubber is not just desirable, but is also quite feasible and profitable.
This text provides a thorough overview of the fundamentals of rubber and the challenges of recycling. However, the heart of the book lies in its detailed explanation of the various processes currently available to breakdown, recycle, and reuse crosslinked rubber. These include --
Unconventional polymer recycling
High-pressure, high-temperature sintering
Ultrasonic and non ultrasonic devulcanization
The use of tire particles as replacement aggregates for low-strength concrete material
The utilization of powdered rubber waste in the production of rubber compounds
The future potential for recycling waste rubber by blending it with waste plastics
Never forgetting that these technologies are meaningless without industry participation, the book concludes with a highly practical discussion on how present market demands can be met with recycled rubber.
Das Handbuch eignet sich für Einsteiger mit wenig Vorkenntnissen ebenso wie als Nachschlagewerk für das Alltagsgeschäft des Praktikers im Markt für Faserverbundkunststoffe.
Die Neuauflage stellt das Thema Product-Engineering mehr in den Vordergrund. Das in die Welt der Kunststoffe einführende Grundlagenkapitel wurde deutlich erweitert, andere Kapitel wurden aktualisiert. Dies betrifft u.a. die Kapitel Polyamide, Polypropylen, Polyvinylchlorid, Polyethylenterephthalat, ungesättigte Polyesterharze, abgewandelte Naturstoffe und elektrisch leitfähige Polymere.
The book offers a candid overview of main issues, including conservation of fossil resources, geopolitical considerations, greenhouse effects, competition with food crops, deforestation, pollution, and disposal of renewable plastics. In addition, an overview of some tools related to sustainability (Life cycle assessments, CO2 emissions, carbon footprint, and more) is provided.
The book is an essential resource for engineers and materials scientists involved in material selection, design, manufacturing, molding, fabrication, and other links in the supply chain of plastics. The material contained is of great relevance to many major industries, including automotive and transport, packaging, aeronautics, shipbuilding, industrial and military equipment, electrical and electronics, energy, and more.Provides key, enabling information for engineers and materials scientists looking to increase the use of renewable plastic materials in their workPresents practical guidance to assist in materials selection, processing methods, and applications development, particularly for designers more familiar with other materials, such as metalsIncludes a candid discussion of the pros and cons of using renewable plastics, considering the technical, economic, legal, and environmental aspects
The book provides a good insight into ongoing research at local and national level within Russia, devoted to the safe disposal of defence-related radioactive waste. It also demonstrates how existing expertise and technology from civilian nuclear waste management programmes can be applied to solving the problems created by nuclear defence programmes.
Contributions address methods of immobilisation, site selection methodology, site characterisation techniques and data interpretation, the key elements of safety/performance assessments of planned deep (geological) repositories for radioactive waste, and radionuclide transport modelling. Concerns associated with certain specific nuclear waste disposal concepts and repository sites are also presented.
Delivering Learning on the Net explores the reality of online education today. Martin Weller chaired the groundbreaking Open University course You, Your computer and the Net, which is now the largest for-credit online course in Europe. Based on this and his experiences elsewhere, the book is a comprehensive resource grounded in practical reality as well as in research. Key issues covered include:
*the Net and its relation to education;
*developing and implementing online courses;
*the key issues surrounding online education.
Teachers, trainers, technologists, administrators and decision-makers working in higher and further education will all find much of value in this book.
In the Dictionary of Textile Finishing the textile engineer will find the correct technical terms for 16.000 keywords within his field of activity in German language and vice versa. The terms cover the latest state of the art. The dictionary is the link between the "Encyclopedia of Textile Finishing" and the "Lexikon der Textilveredelung" from the same author. It is supplemented by a comprehensive collection of acronyms in the textile field (approx. 500 acronyms and their meanings).
Das Buch empfiehlt sich in erster Linie fA1/4r die Ausbildung von Studenten der hAheren Studienjahre und in der Weiterbildung - es kann jedoch auch dem Spezialisten viel Neues bieten.
