ABSTRACT:
The die has first and second die halves, each die half having a plurality of cavities that, when the die halves are in a closed position, align with the cavities in the other die half, thus defining a plurality of voids that define the objects to be formed. Each cavity is aspherical in that the slope of the cavity is never perpendicular to the front surface of the die half, thus facilitating the removal of the objects from the die. A spacing between the front surfaces of the die halves during the injection step of the cycle helps to increase the number of parts that properly release from the die.
