Abstract


Optimization of machining processes is essential for achieving higher productivity and high-quality products in order to remain competitive. The objective of this study is to optimize the process parameter of extrusion blow molding process for making a plastic container of high density polyethylene (HDPE) grade B52A003 produced by the extrusion blow molding process at CIPET Gwalior. Quality of plastic container of HDPE B52A003 material depends on various parameters. In this paper three process parameters namely Barrel temp. (°C), Cooling/cycle time (sec.) and extruder speed (rpm) and three responses haze and clarity, hardness and compressive strength were selected as a quality target. Taguchi Method is a statistical method to improve the process parameters and improve the quality of components that are manufactured. Nine experimental runs based on Taguchi’s L9 (33) orthogonal array were performed followed by the Grey relational analysis to solve the three response optimization problem. Based on the Grey relational grade value and signal to noise ratio based on the higher is better criterion, optimum levels of parameters have been identified. The significance of parameters on overall quality characteristics of the extrusion blow molding process has been evaluated by the analysis of variance (ANOVA). The optimal parameter values obtained during the study have been validated by confirmation experiment.
