This book is of interest for all functions in research, development, new product implementation, production, product engineering in industries which process polymers and plastics. Those who already made use of image analysis in their practice will find useful hints on how to improve and better utilize their methods. Others who did not use these methods so far will find that these inexpensive techniques can provide answers to many important technical problems which are not resolved because just few years ago these methods were not available or too expensive to apply. Only several years ago, these observations were either not quantified at all or various graphical standards were used for comparison to develop a point scale to assign observed images. This was not precise and confusing. The advent of high speed digital cameras working with image processing software is changing this situation. The list of some topics included in the book shows the wealth of opportunities. This book presents results of studies in which imaging and image analyses were used to quantify many important determinants of production technology and product performance such as flow and mixing behavior, optimization of equipment configuration and material homogenization, morphology of plastics, size of polymers domains in blends, compatibilization methods and conditions, effects of grafting, reasons for surface roughness, scratch and mar resistance, fiber orientation, improved barrier properties, improved magnetic permeability, improved mechanical properties, distribution of voids in laminates, determination of cell sizes in cellular plastics, formation of crazes during fatigue, fiber radius determination during spinning, blister formation and adhesion, effects of glass fiber orientation on weld strength, analysis of welding process, dispersion of agglomerates formed by additives and the effect of mixing and transport conditions, formation of gels and impurities, particles structure and distribution, rate of crystallization, and many others. Having numerical data it is possible to optimize the processes to increase output, decrease a reject rate, save materials, and improve product properties.
Considering that every product must appeal to a customer and perform under conditions of its use, these studies are the most important for optimizing numerous conflicting properties. For example in one research, product performance is combined with high output rate and requirement of low weight. The potential applications of image analysis allow to follow these interrelations to optimize a product which is why research and production are eager to apply this emerging technology. The number of research reports on this subject is systematically growing. The methods of observation, such as various forms of microscopy, tracers, and lasers, are simple and in most cases available in most facilities.

The book contains references to various applications already in use, methods of image capture, data processing, hardware and software required. The examples of processes discussed include: extrusion, extruding reactors, injection molding, impregnation, foam production, film manufacture, compression molding, vulcanization, melt spinning, reactive blending, welding, blow molding, conveying, composite manufacture, compounding and termosetting. The examples of studies and improvements include: increased homogeneity of dye, pigment and filler mixing, improved fiber orientation, increased tooth stiffness in composite gears, the rate of spherulites growth, optimization of screw configuration, increased miscibility in polymer blends, study of polymer crystallization rate, melt flow analysis, void content, particle size in polymer blends, pore size and shape in foams, cell density in foams, modifier dispersion, improvement of bidirectional properties, effect of low molecular additives on morphology, interparticle distance, effect of mixing conditions and geometry on morphology, crack formation during fatigue testing, mechanism of crazing, chemical resistance, oil penetration, kinetic measurement of fiber diameter, stress profile, quantified flow visualization, effect of compatibilization, domain distribution, correlation of morphology with mechanical performance, analysis of melt fracture aids, surface roughness, droplet/fiber transition, barrier properties, effect of orientation on electric conductivity, peel adhesion, fiber length after processing, fractal dimension, nucleation, thermography, thermal imaging, failure analysis, agglomerate dispersion, and impurity monitoring. The large variety of processing methods, possible studies and improvements show that this book is of interest of the entire cross-section of plastic manufacturing industry. It offers data which not only allow to better understand materials and processing methods but the book helps in process optimization and development of processes having higher throughput and superior performance.
This book is about the design and processing of various materials rather than algorithms and design of image analysis equipment. But by showing actual research and data in a form familiar to any technologist in plastics industry, it demonstrates benefits and capabilities of the methods.
