Abstract: Today-s the plastic injection moulding process is the widely used manufacturing process for the production plastic products. The main aim of this paper is to study the effect of different parameters on polypropylene work material for a plastic injection moulding process during manufacturing of bottle cover. The optimization of different parameters like melting temperature, injection pressure and cooling time are done which mainly affects the mechanical properties of the bottle cover. The taguchi method, signal to noise (S/N) ratio and analysis of variance (ANOVA) are employed to analyse the effect of process parameters of plastic injection moulding on the tensile strength of the bottle cover of polypropylene material.
