The maximum temperature fields in both cases can be seen towards the outer end of the die plate and bearing
region. When we look at the flow of the aluminum in this region it is observed that as the aluminum flows vertically
down towards the die plate, it is then split into two flow fields one towards the bearing and the other towards the end
of the die plate (Fig 13) to fill the void. This flow of the billet towards the back end of the die plate causes the high
temperature distributions seen in Figures 12 (a) &(c) as well as causes tool wear occurring on the die plate shown in
Figure 14.
