Abstract

Injection molding process is widely used in industry for manufacturing of various kinds of products made of plastics. It is a fundamental polymer processing practice in plastic industry. In this process various optimization techniques are used to improve the product quality. Process parameters play a vital role in injection molding and have an effect on the worth of the product made up of different plastics. Along with molding conditions,plastic properties have a significant impact on the quality of plastic products in injection molding and optimised parameters enhance the quality of product and shrink the cycle time. In this research paper, the optimization of process parameters is implemented for polypropylene to manufacture a pharmaceutical cup. The technique applied for optimizing molding parameters is full factorial design. Analysis of Variance (ANOVA) technique is applied in Minitab software to find the significance of each parameter. Selected parameters like total time, injection pressure, injection temperature and mould’s temperature are taken and analyzed during experimentation and best applicable combination of these parameters is set to get the desired results. The results obtained after performing experiments suggest that total time and mould temperature are significant factors in shaping the product’s quality.
