Plastics: Materials and ProcessingAn introduction to plastics for a wide range of students who need to either gain, improve, or refresh their knowledge of plastic materials and manufacturing. The text discusses both materials and manufacturing processes in a logical presentation. While providing a fundamental overview of a broad spectrum of topics, the text's high level of detail makes it valuable as both an introductory text and, later, a professional reference manual. This edition features more logical organization, dividing the previous tooling and testing chapters into tooling sections that appear within each of the processing chapters and testing sections that appear within each of the plastics properties chapters. It shifts coverage of design to follow the chapters on properties, giving an immediate example of how properties can be used and should allow students to flow more efficiently and effectively through the texts contents without digressions and interruptions. |
