Given the importance of injection molding as a process as well as the simulation industry that supports it, there was a need for a book that deals solely with the modeling and simulation of injection molding. This book meets that need. The modeling and simulation details of filling, packing, residual stress, shrinkage, and warpage of amorphous, semi-crystalline, and fiber-filled materials are described. This book is essential for simulation software users, as well as for graduate students and researchers who are interested in enhancing simulation. And for the specialist, numerous appendices provide detailed information on the topics discussed in the chapters. Contents: Part 1 The Current State of Simulation: Introduction, Stress and Strain in Fluid Mechanics, Material Properties of Polymers, Governing Equations, Approximations for Injection Molding, Numerical Methods for Solution Part 2 Improving Molding Simulation: Improved Fiber Orientation Modeling, Improved Mechanical Property Modeling, Long Fiber-Filled Materials, Crystallization, Effects of Crystallizations on Rheology and Thermal Properties, Colorant Effects, Prediction of Post-Molding Shrinkage and Warpage, Additional Issues of Injection-Molding Simulation, Epilogue Appendices: History of Injection-Molding Simulation, Tensor Notation, Derivation of Fiber Evolution Equations, Dimensional Analysis of Governing Equations, The Finite Difference Method, The Finite Element Method, Numerical Methods for the 2.5D Approximation, Three-Dimensional FEM for Mold Filling Analysis, Level Set Method, Full Form of Mori-Tanaka Model

This practical introductory guide to injection molding simulation is aimed at both practicing engineers and students. It will help the reader to innovate and improve part design and molding processes, essential for efficient manufacturing. A user-friendly, case-study-based approach is applied, enhanced by many illustrations in full color. The book is conceptually divided into three parts: Chapters 1–5 introduce the fundamentals of injection molding, and how molding simulation methodology is developed, especially focusing on the effects on molding quality from the rheological, thermodynamic, thermal, mechanical, and kinetic properties of plastics, as well as curing kinetics for thermoset plastics. Chapters 6–11 introduce CAE verification on injection molding including design guidelines of part, gating, runner, and cooling channel systems. Temperature control in hot runner systems, prediction and control of warpage, and fiber orientation are also discussed. Chapters 12–17 introduce research and development in innovative molding, illustrating how CAE is applied to advanced molding techniques, including co-/bi-injection molding, gas-/water-assisted injection molding, foam injection molding, powder injection molding, resin transfer molding (RTM), and integrated circuit (IC) packaging. The 2nd edition contains many updates, including elaboration of material measurement data, connection of Smart Design and Smart Manufacturing, demonstration of the flow-induced fiber orientation effect, implementations of material characterization methods on PU reactive foaming and RTM, studies of dispensing control and creeping behaviors effects on IC underfill process, and much more. Several CAE case study exercises for execution in Moldex3D software are included to allow readers to practice what they have learned and test their understanding.

In plastics technology, a wide variety of computer programs are used for the design and optimization of molded plastic parts and for mold design. These programs calculate the filling process, the holding pressure phase, and the cooling phase of the molded part in the mold. The results include, for example, pressures, temperatures, weld/knit lines, and voids. The shrinkage and warpage behavior of the molded part can also be predicted. Understanding and interpreting these simulation results is not trivial, although they are colorful representations with numerical values. Regardless of whether one has many years of experience as a designer, a mold maker, or an injection molder, or whether one is in training or studying, simulation is becoming increasingly important. For this reason, experts who know how to use these programs correctly are increasingly sought after in the market. This book is intended to expand readers' specialist knowledge in the field of simulation, thereby increasing their ability to recognize and avoid molding errors at an early stage. Readers will also learn to draw the right conclusions from the simulation results and develop their own solutions.
