Available in PDF, EPUB and Kindle. Book excerpt: This practical introductory guide to injection molding simulation is aimed at both practicing engineers and students. It will help the reader to innovate and improve part design and molding processes, essential for efficient manufacturing. A user-friendly, case-study-based approach is applied, enhanced by many illustrations in full color. The book is conceptually divided into three parts: Chapters 1–5 introduce the fundamentals of injection molding, focusing the factors governing molding quality and how molding simulation methodology is developed. As they are essential to molding quality, the rheological, thermodynamic, thermal, mechanical, kinetic properties of plastics are fully elaborated in this part, as well as curing kinetics for thermoset plastics. Chapters 6–11 introduce CAE verification of design, a valuable tool for both part and mold designers toward avoiding molding problems in the design stage and to solve issues encountered in injection molding. This part covers design guidelines of part, gating, runner, and cooling channel systems. Temperature control in hot runner systems, prediction and control of warpage, and fiber orientation are also discussed. Chapters 12–17 introduce research and development in innovative molding, illustrating how CAE is applied to advanced molding techniques, including co-/bi-Injection molding, gas-/water-assisted injection molding, foam injection molding, powder injection molding, resin transfer molding, and integrated circuit packaging. The authors come from the creative simulation team at CoreTech System (Moldex3D), winner of the PPS James L. White Innovation Award 2015. Several CAE case study exercises for execution in the Moldex3D software are included to allow readers to practice what they have learned and test their understanding.

Download or read book Molding Japanese Minds written by Sheldon Garon and published by Princeton University Press. This book was released on 2021-05-11 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: How has the Japanese government persuaded its citizens to save substantial portions of their incomes? And to care for the elderly within the family? How did the public come to support legalized prostitution as in the national interest? What roles have women's groups played in Japan's "economic miracle"? What actually unites the Japanese to achieve so many economic and social goals that have eluded other polities? Here Sheldon Garon helps us to understand this mobilizing spirit as he taps into the intimate relationships everyday Japanese have with their government. To an extent inconceivable to most Westerners, state directives trickle into homes, religious groups, and even into individuals' sex lives, where they are frequently welcomed by the Japanese and reinforced by their neighbors. In a series of five compelling case studies, Garon demonstrates how average citizens have cooperated with government officials in the areas of welfare, prostitution, and household savings, and in controlling religious "cults" and promoting the political participation of women. The state's success in creating a nation of activists began before World War II, and has hinged on campaigns that mobilize the people behind various policies and encourage their involvement at the local level. For example, neighborhoods have been socially managed on a volunteer basis by small-business owners and housewives, who strive to rid their locales of indolence and to contain welfare costs. The story behind the state regulation of prostitution is a more turbulent one in which many lauded the flourishing brothels for preserving Japanese tradition and strengthening the "family system," while others condemned the sexual enslavement of young women. In each case, we see Japanese citizens working closely with the state to recreate "community" and shape the thought and behavior of fellow citizens. The policies often originate at the top, but in the hands of activists they take on added vigor. This phenomenon, which challenges the conventional dichotomy of the "state" versus the "people," is well worth exploring as Western governments consider how best to manage their own changing societies.

Download or read book Language as a Local Practice written by Alastair Pennycook and published by Routledge. This book was released on 2010-04-05 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Language as a Local Practice addresses the questions of language, locality and practice as a way of moving forward in our understanding of how language operates as an integrated social and spatial activity. By taking each of these three elements – language, locality and practice – and exploring how they relate to each other, Language as a Local Practice opens up new ways of thinking about language. It questions assumptions about languages as systems or as countable entities, and suggests instead that language emerges from the activities it performs. To look at language as a practice is to view language as an activity rather than a structure, as something we do rather than a system we draw on, as a material part of social and cultural life rather than an abstract entity. Language as a Local Practice draws on a variety of contexts of language use, from bank machines to postcards, Indian newspaper articles to fish-naming in the Philippines, urban graffiti to mission statements, suggesting that rather than thinking in terms of language use in context, we need to consider how language, space and place are related, how language creates the contexts where it is used, how languages are the products of socially located activities and how they are part of the action. Language as a Local Practice will be of interest to students on advanced undergraduate and post graduate courses in Applied Linguistics, Language Education, TESOL, Literacy and Cultural Studies.
Download or read book Precision Injection Molding written by Jehuda Greener and published by Hanser Publications. This book was released on 2006 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the key aspects of the production of high precision components is the need to meet extremely tight dimensional tolerances, typically in the submicron range, and maintain these tolerances over the practical lifetimes of the molded articles. In addition, as many of the precision components are utilized in various optoelectronic systems and devices, control of optical and electrical properties is often crucial. The strict control of dimensional and electro-optical properties requires a systematic reexamination of the conventional injection-molding process with special consideration of its impact on the dimensions and electro-optical characteristics of the molded article. This volume examines precision injection molding from different perspectives, covering materials, process and hardware aspects of the technology, with special emphasis on the dimensional integrity and stability of the molded components. Special topics covered in this volume include: dimensional stability of molded plastics, models for warpage development, compact disc molding, process control, crystallization phenomena in injection molding, micro-molding and microfluidics.
Download or read book Robotics in Practice written by Joseph F. Engelberger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE REAL THING by Isaac Asimov Back in 1939, when I was still a teenager, I began to write (and publish) a series of stories about robots which, for the first time in science fiction, were pictured as having been deliberately engineered to do their job safely. They were not intended to be creaky Gothic menaces, nor outlets for mawkish sentiment. They were simply well-designed machines. Beginning in 1942, I crystallized this notion in what I called 'The Three Laws of Robotics' and, in 1950, nine of my robot stories were collected into a book, I, Robot. I did not at that time seriously believe that I would live to see robots in action and robotics becoming a booming industry .... Yet here we are, better yet, I am alive to see it. But then, why shouldn't they be with us? Robots fulfil an important role in industry. They do simple and repetitive jobs more steadily, more reliably, and more uncomplainingly than a human being could - or should. Does a robot displace a human being? Certainly, but he does so at a job that, simply because a robot can do it, is beneath the dignity of a human being; a job that is no more than mindless drudgery. Better and more human jobs can be found for human beings - and should.
