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 sim-ulation technologies, without losing sight of still useful classical approaches.23990
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 polymers, highlighting
the efforts to simulate particle–particle interactions. The application of the mul-
tilevel micro–macro approach to fiber suspensions is also demonstrated. Chapter 6
presents methods to predict shrinkage and warpage. Micromechanics for
mechanical property predictions is also included in this chapter. Finally, Chap. 7
deals with the application of boundary integral equations to the mold cooling
analysis. Chapter 8 provides a guide to some computational techniques used in
simulations of melt flow in mold filling and packing, deformation of the solid
parts, and mold cooling. Cartesian tensors are used in this book for conciseness.
