Offered as a two-volume set, this publication describes the results of a five-year collaborative project sponsored by the German Research Council investigating various techniques for micro-engineering that utilize metallic and ceramic materials. Volume 1 deals with design, tooling, and replication techniques based on injection molding. Its 12 chapters address such topics as modeling and validation in design; micro end milling of hardened steel; and micro-powder injection molding of metal and ceramic micro-components. The volume is illustrated with b&w photographs and drawings. Most of the contributors are affiliated with either Karlsruhe Technical U. or the Research Center Karlsruhe in Germany.

Microstructures, electronics, nanotechnology - these vast fields of research are growing together as the size gap narrows and many different materials are combined. Current research, engineering sucesses and newly commercialized products hint at the immense innovative potentials and future applications that open up once mankind controls shape and function from the atomic level right up to the visible world without any gaps.
In this volume, authors from three major competence centres for microengineering illustrate step by step the process from designing and simulating microcomponents of metallic and ceramic materials to replicating micro-scale components by injection molding.

Prof. Dr.-Ing. Detlef Lohe studied mechanical engineering at the Technical University of Karlsruhe, Germany and obtained his Ph.D. in 1980. After heading the microstructure and mechancal behaviour working group there, he was appointed in 1991 as professor for materials science at Paderborn University, Germany, where he received an award for outstanding teaching achievements in 1994. In the same year, he returned to the Institute for Materials Science and Enginering I at Karlsruhe Technical University as its Director. He is Speaker of the Collaborative Research Centre 499 "Design, production and quality assurance of molded microparts constructed of metals and ceramics" and has been a Senator of the Deutsche Forschungsgemeinschaft (DFG) since 2003. His research interests focus on metallic and ceramic materials properties and durability under different kinds of stress, component manufacture and behaviour, optimisation of heat treatment methods, and failure analysis.
Prof. Dr.-Ing. Jurgen Hau?elt studied Physics and Materials Sciences at the University of Erlangen, Germany. After his doctorate and a research stay at Stanford University he joined Degussa AG in 1977, starting in metals research. After having worked as technical director in Degussa's subsidiary in New York City, he returned to Germany in 1985 and was first in charge of metals research, then managed the entire materials development und process technology of Degussa's corporate division "Metals". In 1993 he joined Forschungszentrum Karlsruhe as head of the Institute of Materials Research III. In addition, he was appointed professor at Freiburg University as Chair for Micromaterials Process Technology at IMTEK in 1996. In 1998 he became member of the supervisory board of Norddeutsche Affinerie AG, Hamburg.
