[e-mail] ABTRACT: Injection molding process is widely used process for producing plastic products in industries. operating parameters of injection molding machine are needed to produced better quality of product. In this thesis Taguchi method is used to optimize the process parameter combination from the three controllable process parameters on setting of three level to improve the quality characteristics (shrinkage). melting temperature, packing pressure & injection pressure is selected for the experiment. Optimization of injection molding process parameter will be carried out using HDPE (50MA180) as the material. The design of experiments (DOE) is used to optimize input parameters and achieve good results using “orthogonal arrays” (OA) by Taguchi method. L27 orthogonal array was selected for

This sector is the fastest growing sector in the Indian economy like globe. Now a day’s injection moulding bears their responsibility of mass producing plastic components to meet the rapidly rising market demand as a multitude of different types of consumer products including medical, electronics and automobile. To sustain in the market, it is required to produce quality products at least price. The most effective process for mass production of plastic products is injection moulding process. Injection moulding has high efficiency, largest yield and highest dimensional accuracy among all the processing methods. Most of the thermoplastic materials are injection moulded and more than half of all polymer processing equipment’s are for injection
