Injection moulding process is widely used in manufacturing and producing daily plastic products. The gate location and sprue significantly influence the stability of molten plastic flow, especially for complex products. Without the proper gate location and parameters, the plastic flow will cause insufficient filling and defects. This paper analyses the effect of gate location and sprue design during the filling and packing process through the simulation method. The simulation software was utilised in the current study. The plastic casing of the power tool hand drill was considered for the injection moulding process. The molten plastic behaviour was visualised via the filling contour. The pressure, shear stress, and volumetric shrinkage were also analysed. The result obtained shows that the molten plastic flow behaviour depends on the selected parameters. The selected parameter significantly changes a few variables chosen where gate locations are the most significant to the plastic flow.
