Computational Analysis and Simulation of Polymer Injection Molding

This book provides an in-depth exploration of numerical methods applied to polymer injection molding technology. It explains the physical principles governing melt flow, heat transfer, and pressure development inside the mold cavity, with particular attention to the non-Newtonian behavior of polymer materials. The mathematical formulation of conservation laws is clearly presented and translated into computational algorithms suitable for engineering analysis.Different numerical techniques, including finite difference, finite volume, and finite element approaches, are discussed for simulating the filling, packing, and cooling phases. Practical implementation strategies using MATLAB are introduced to help readers understand how theoretical models are transformed into working simulation codes.Through analytical discussion and applied examples, the book supports optimization of processing parameters, improvement of product quality, and reduction of manufacturing defects. It is intended for researchers, graduate students, and professionals engaged in polymer processing and computational engineering.
