the flow analysis of the plastic part was carried out with Moldflow software to enable the selection of the best gate location Figure 6a. The figure indicates that the best point for the gate location is the middle feeder at the centre of the part. As the distortion and warpage of the part after injection was vital from the functionality point of view and it has to be kept ata minimum level, the same software was also utilised to yiled the warpage analysis. Figure 5b shows the results implying the fact that the warpage well after injection remains within the predefined dimensional tolerances. 6. Conclusions In the plastic injection moulding, the CAD model of the plastic part obtained mercial 3D programs could be used for the part performance and injection process analyses. With the aid of
