Today engineers, designers, buyers and all those who have to work with plastics face a dilemma. There has been a proliferation of test methods by which plastic properties are measured. The property data measured by these test methods are not identical and sometimes have large differences. How are engineers, designers, buyers going to decide the type and resin grade and their property data? Which are the valid test methods? The right plastic property data are the difference between success and failure of a design, thus making the property selection process critical. For the first time this book provides a simple and efficient approach to a highly complex and time consuming task. There are over 26,000 different grades of polymers and millions of parts and applications, further adding to the difficulty of the selection process.Selection of Polymeric Materials steers engineers and designers onto the right path to selecting the appropriate values for each plastic property. A large amount of property information has been provided to teach and assist the plastic part designer and others in selecting the right resin and properties for an application. Various standards including ASTM, ISO, UL, and British Specifications have been discussed to help the readers in making sound decisions - A simple and efficient approach to a highly complex and time consuming task - Allows engineers to select from various standards including ASTM, ISO, UL, and British Specification - Presents information on properties such as tensile strength, melt temperature, continuous service temperature, moisture exposure, specific gravity and flammability ratings - Tried and true values narrow myriad choices down quickly for readers

The development of products in disciplines such as mechanical, electrical, or software engineering is a challenging task. Costs have to be reduced, the ti- to-market has to be shortened, and quality has to be improved. Skilled engineers andsophisticatedtoolsforsupportingtechnicalworkarenecessaryprerequisites, yettheyarenotsu?cientformeetingtheseambitiousgoals.Inaddition,thework of developers must be coordinated so that they cooperate smoothly. To this end, the steps of the development process have to be planned, an engineer executing a task must be provided with documents and tools, the results of development activities have to be fed back to management which in turn has to adjust the plan accordingly, the documents produced in di?erent working areas have to kept consistent with each other, etc. This book reports on models and tools for managing development processes. It provides both a survey of the current state of the art and presents our own contributions. The material covered in this book is based on research in di?- ent engineering disciplines (mechanical, software, and chemical engineering). It presents a uni?ed view on the management of development processes in these disciplines.

In the 21st century, computer integrated manufacturing (CIM) systems will not only be the economic development tools but will also be the essential means of achieving a higher level of flexibility, cohesiveness and performance. CIM systems are beginning to settle into our society and industries, with greater emphasis on the integration of economic, cultural and social aspects together with design, planning, factory automation and artificial intelligent systems.This volume of proceedings brings together 10 keynote and invited speaker addresses, and over 180 papers by practitioners from 28 countries. It documents current research and in-depth studies on the fundamental aspects of advanced CIM systems and their practical applications. The papers fall into 3 main sections: CIM Related Issues; Industrial AI Applications Aspects; and Concurrent Engineering, Advanced Design, Simulation and Flexible Manufacturing Systems.

This book provides a simplified, practical, and innovative approach to understanding the design and manufacture of plastic products in the World of Plastics. The concise and comprehensive information defines and focuses on past, current, and future technical trends. The handbook reviews over 20,000 different subjects; and contains over 1,000 figures and more than 400 tables. Various plastic materials and their behavior patterns are reviewed. Examples are provided of different plastic products and relating to them critical factors that range from meeting performance requirements in different environments to reducing costs and targeting for zero defects. This book provides the reader with useful pertinent information readily available as summarized in the Table of Contents, List of References and the Index.

In the competitive business arena companies must continually strive to create new and better products faster, more efficiently, and more cost effectively than their competitors to gain and keep the competitive advantage. Computer-aided design (CAD), computer-aided engineering (CAE), and computer-aided manufacturing (CAM) are now the industry standa
