Summary:

This book offers an up-to-date, platform-independent introduction to injection molding simulation, which plays a very important role in the design of molds and molded parts as well as process development and optimization. The content is structured and conveyed within an engineering framework. Complicated mathematical derivations are avoided as far as possible. The necessary environment of the injection molding simulation is illuminated alongside, so that the build-up of a suitable simulation model and the interpretation of the results are made possible, and knowledge of the model-specific limits is imparted. Guidance is also provided regarding the interpretation of results so that they can be better evaluated quantitatively. The book is designed as a textbook and thus is suitable to accompany courses covering injection molding simulation. The content is largely independent of any particular software package; however, introductory practice examples for Autodesk Moldflow Insight, CADMOULD and Moldex3D are included as step-by-step instructions.
