The collection of techniques gathered in this book help illustrate material/process/property relationships for materials and processes in the plastics industry. With the recent increases in computing power and scope, as well as advances in software engineering, imaging has already become a universal tool. Image processing and image analysis have become common expressions are widely recognized within the scientific community. The imaging techniques employed range from visible optical methods to scanning and transmission electron microscopy, x-ray, thermal wave infrared, and atomic force microscopy. Image analysis is used to monitor/ characterize a variety of processes. Processes included within this book are: extrusion, injection molding, foam production, film manufacture, compression molding, blow molding, vulcanization, melt spinning, reactive blending, welding, conveying, composite manufacture, compounding, and thermosetting.
