Optimization of Process Parameters of Plastic Extrusion in Pipe Manufacturing

The objective of this study present a systematic approach to find the root causes for the occurrence of defects and wastage in plastic extrusion process in the pipe manufacturing industries. It is very essential to learn the process parameter and the defect in the plastic pipe manufacturing process to optimize it. For the optimization Taguchi technique is used in this paper. Taguchi Method is a statistical approach to optimize the process and improve the quality of components that are manufactured. The experiment was analyzed using Minitab 17 software, interpretation has made, and optimized factor settings were chosen. In this analysis three factors namely take-off speed, melting temperature, extruder speed, were considered. Accordingly, a suitable orthogonal array was selected and experiments were conducted. After conducting the experiments the diameters were measured and Signal to Noise ratio was calculated. With the help of graph and table, optimum parameter values were obtained.
