Parameter Optimization of Injection Molding of Polypropylene by using Taguchi Methodology

Injection molding is an important polymer processing operation in the plastic industry. In this process, polymer is injected into a mold cavity, and solidifies to the shape of the mold. Optimizing the parameters of the injection molding process is critical to enhance productivity. For process optimization, parameters must operate at optimum levels for acceptable performance. Taguchi method is one of the methods of optimization, in which orthogonal array is generated based on experimental design. Optimization of injection molding process parameters will be carried out using polypropylene (PP) as the molding material Keywords - Coolant Flow rate, Injection Molding Optimization, Taguchi methodology,
