Preface
The purpose of this book is to introduce the reader to some topics relevant to the modeling of the injection molding process. Injection molding processing links to various scientific and engineering disciplines such as rheology, mechanical and chemical engineering, polymer science and computational methods. While it is impossible to address every aspect of such a broad range of issues, this book is intended to address the up-to-date status of fundamental understanding and simulation technologies, without losing sight of still useful classical approaches. The book is organized as follows. In Chap. 1, a general overview of the injection molding stages, material classification, rheological characterization of polymers, and the development of numerical simulation methods is presented as an introduction. In Chap. 2, fundamentals of rheology are described, focused on constitutive models useful in practice. Chapter 3 describes assumptions and mathematical models for filling and packing phases of the injection molding process. Chapter 4 is devoted to flow-induced crystallization and the processing– morphology–properties relationship. This is a very active field, which has attracted great attention in recent years. Chapter 5 discusses the modeling of flow-induced orientation distribution in injection molded fiber-reinforced polyme
