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. 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.
