The mold is fabricated from aluminum (as opposed to cast) because there are so many moving parts integral to the mold. View 1 shows the rear of the mold as a core-pull in its molding position. To de-mold the part that core-pull will be retracted (towards the viewer). In this view, the "lifters" needed to create the perimeter undercuts are not present. View 2 shows the precision machining and fabrication of the "hinging" mechanisms for the perimeter "lifters". View 3 is the articulating plug-assist in its fully extended mode. To de-mold the part, the feature on the left will retract back to the left. View 4 shows the temperature-control plumbing, unusual because it is external. This is due to all the moving parts inside the mold cavity not allowing adequate room for uniform distribution of the cooling medium necessary for consistent molding.
