Available in PDF, EPUB and Kindle. Book excerpt: Polymerie materials have been replacing other conventional materials like metals, glass and wood in a number of applications. The use of various types of fillers incorporated into the polymer has become quite common as a means of reducing cost and to impart certain desirable mechanieal, thermal, electrieal and magnetic properties to the polymers. Oue to the energy crisis and high priees of petrochemieals, there has been a greater demand to use more and more fillers to cheapen the polymerie materials while maintaining and/or improving their properties. The advantages that filled polymer systems have to offer are normally offset to some extent by the increased complexity in the rheological behavior that is introduced by the inclusion of the fillers. Usually when the use of fillers is considered, a compromise has to be made between the improved mechanieal properties in the solid state, the increased difficulty in melt processing, the problem of achieving uniform dispersion of the filler in the polymer matrix and the economics of the process due to the added step of compounding. It has been recognized that addition of filler to the polymer brings a change in processing behavior. The presence of the filler increases the melt viscosity leading to increases in the pressure drop across the die but gives rise to less die swell due to decreased melt elasticity.

Available in PDF, EPUB and Kindle. Book excerpt: Ceramic injection molding (CIM) is a high volume, near net shaping process used to manufacture ceramic parts with complex features and shapes. In CIM design it is important to understand the molding behavior as a function of powder-polymer (feedstock) composition in order to achieve desired part dimensions and properties, at high production rates. Standard practices in CIM product design typically involve performing multiple trial-and-error molding experiments for various feedstock compositions. Alternatively, CIM design simulations can be performed to reduce the iterations. However, they require the measurement of physical, thermal and rheological feedstock properties and the availability of such data is limited. Currently there is no reliable design approach available to perform mold-filling simulations for compositions that differ from those with measured feedstock properties. The present work develops and evaluates a new method to estimate feedstock properties critical to performing CIM simulations. The method utilizes the material properties of ceramic fillers from literature along with experimental measurements of an unfilled wax-polymer binder system. The current work is divided into three parts. In the first part, nine different ceramic feedstocks and a wax-polymer binder, whose material properties were measured by our research group, formed the basis for this study. Experimental and estimated feedstock properties of these nine systems were compared to quantitatively evaluate the quality of correspondence. The second part uses the measured and estimated physical, thermal, and rheological properties for an aluminum nitride feedstock to perform mold-filling simulations to compare the differences in the output of CIM simulations based on the input feedstock property data from experiments and estimates. The third part examines the merits of CIM simulations to predict mold-filling behavior by conducting injection-molding experiments for an aluminum nitride feedstock. The findings from the current study can be used to improve CIM design practices and serve as a guide for estimating ceramic feedstock properties to conduct mold-filling simulations.

Download or read book Injection Molding written by Rong Zheng and published by Springer. This book was released on 2011-06-22 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers fundamental principles and numerical methods relevant to the modeling of the injection molding process. As injection molding processing is related to rheology, mechanical and chemical engineering, polymer science and computational methods, and is a rapidly growing field, the book provides a multidisciplinary and comprehensive introduction to the subjects required for an understanding of the complex process. It addresses the up-to-date status of fundamental understanding and simulation technologies, without losing sight of still useful classical approaches. The main chapters of the book are devoted to the currently active fields of flow-induced crystallization and orientation evolution of fiber suspensions, respectively, followed by detailed discussion of their effects on mechanical property, shrinkage and warpage of injection-molded products. The level of the proposed book will be suitable for interested scientists, R&D engineers, application engineers, and graduate students in engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Several ceramic parts have already proven their suitability for serial application in automobile engines in very impressive ways, especially in Japan, the USA and in Germany. However, there is still a lack of economical quality assurance concepts. Recently, a new generation of ceramic components, for the use in energy, transportation and environment systems, has been developed. The efforts are more and more system oriented in this field. The only possibility to manage this complex issue in the future will be interdisciplinary cooperation. Chemists, physicists, material scientists, process engineers, mechanical engineers and engine manufacturers will have to cooperate in a more intensive way than ever before. The R&D activities are still concentrating on gas turbines and reciprocating engines, but also on brakes, bearings, fuel cells, batteries, filters, membranes, sensors and actuators as well as on shaping and cutting tools for low expense machining of ceramic components. This book summarizes the scientific papers of the 7th International Symposium "Ceramic Materials and Components for Engines". Some of the most fascinating new applications of ceramic meterials in energy, transportation and environment systems are presented. The proceedings shall lead to new ideas for interdisciplinary activities in the future.
