Optimization of process parameters on warpage of plastic part fabricated using injection moulding via Taguchi method

In this study, the main objective is to optimize the injection moulding process parameters such as mould temperature, melt temperature, injection time and cooling time on warpage of plastic. Autodesk Simulation Moldflow software was used to run the simulation of the plastic part to get the recommended parameters. The experiment was conducted by using Taguchi L9 orthogonal array. It was found that optimum parametric combination are at mould temperature of 56 degrees C, melt temperatureof 250 degrees C, injection time of 0.70s and cooling time of 15.4 seconds. The melt temperature was identified as the most significant parameter that affect the warpage of plastic part.
