Claim:
1. A multiple material carrier plate assembly with mating pairs of three axis floating replaceable pre-molded inserts each having at least one mold cavity, inserted into window openings in two removable carrier plates for use in precision molding, the assembly comprising: a mating pair of removable carrier plates adapted to be installed in a precision molding device, each of the carrier plates having a mating matrix of elongated precision openings arranged in a given pattern and precision position for precision alignment of the mating pair of carrier plates, the carrier plates having at least one pair of window openings, with one of the window openings in each of the mating carrier plates, adapted for aligning with the other mating window opening when the carrier plates are moved together in a molding process, the carrier plates fabricated of a ferrous material adapted for long-term use in a production precision molding apparatus, each of the window openings having a continuous recessed groove in an interior edge of the window opening around the entire window opening; at least one pair of replaceable pre-molded inserts each having at least one mold cavity, each adapted to be inserted in one of the pair of mating window openings to secure each of the pre-molded inserts within one of the mating window openings of the carrier plate, each of the pre-molded inserts having a continuous groove around an entire outside perimeter edge and each of the pre-molded inserts having at least one mold cavity; the mating pair of pre-molded inserts further comprising a plurality of pairs of mating alignment elements adapted for automatically lining up the pair mating pre-molded inserts precisely during a precision molding process, the mating pre-molded inserts fabricated of a nonferrous moldable material adapted for withstanding operating temperatures and compression pressure required for a production precision molding process; a resilient rubber-like preformed retainer ring stretched around each of the pre-molded inserts perimeter edge and each tension fit into the continuous groove encircling the perimeter edge with a portion of the retainer ring extending outside of the perimeter edge of the pre-molded insert, so that each insert is adapted to be inserted into one of the window openings with the retainer ring snapping into the recessed groove around the window opening so that the pre-molded insert is adapted to be insertable, removable and replaceable, the retainer ring having a resilience sufficient to allow motion of the insert in an X axis, Y axis and Z axis thereby forming a three-axis floating mold, the mating pre-molded inserts being adapted to be moved together into a mating position in a precision molding process, the retainer ring fabricated of a nonferrous rubberlike material adapted for withstanding the operating temperatures required for production precision molding; thereby forming a multiple material carrier plate assembly with mating pairs of three axis floating replaceable pre-molded inserts each having at least one mold cavity, inserted into window openings in two removable carrier plates for use in precision molding.
