The Influence of Temperature Dependant Parameters in Plastic 0.0nd Metal Injection Molding using Taguchi Method
Keywords:Metal injection molding, simulation, Taguchi
AbstractInjection molding is a promising manufacturing process because of several advantages. Conventional injection molding was dominated by plastic as the raw material, but for better engineering properties feasibility, metal injection molding (MIM) has been given special attention. However, because of different properties and rheology, processing parameters for both processes must be treated accordingly. In this paper, the most influencing process parameter is identified for both processes using the state of the art Taguchi method. Simulation using Moldflow software is conducted with various process settings. From the study, it is proven that due to rheological behaviour, all the input parameters influence the MIM process while only one parameter is dominating during the injection molding of polypropylene.
