Abstract

Nowadays, plastic materials are one of the most important materials having high demand in creating various products. In injection moulding, process parameters play an important element since it give an impact to the quality of the product. This project studies the effect of injection moulding parameters on material characteristic of two plate mould with different material using flow analysis. It focuses on the effect of injection moulding parameters on the each response which are volumetric shrinkage at ejection, fill time, in-cavity residual stress and deflection by using Moldflow simulation software. The parameters that have been selected in this study were melt temperature, mould temperature, injection time and cooling time. Then optimization of parameters for each response was find by using Taguchi method and Analysis of Variance (ANOVA). The dumbbell of plastic part was designed by CATIA software. The material used in this project are Polypropylene (PP) and Polypropylene filled Talc. It is found that, the lowest value of each response for material PP shows deflection at run 9, fill time at run 1, volumetric shrinkage at run 1 and residual stress at run 3. While for PP filled Talc shows the lowest value of fill time at run 1, deflection at run 8, volumetric shrinkage at run 7 and residual stress at run 3. Through ANOVA, it shows that melt temperature is the significant parameter for injection moulding process.
