Plastics: Materials and ProcessingFor courses in Plastics, Materials and Manufacturing found in departments of mechanical, industrial or manufacturing technology or engineering; also for any beginning course in Plastics in engineering or technology programs. This book is designed to introduce plastics to a wide range of students who need to either gain, improve, or refresh their knowledge of plastic materials and manufacturing. It fully discusses both materials and manufacturing processes in a carefully-constructed and 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. |
