Patent ID: 8721322

Claim:
An injection molding device comprising: a cartridge assembly defining a chamber for housing a canister of premixed, one-to-one ratio mixture of thermoset elastomer, the chamber of the cartridge assembly comprises a substantially tubular member having a removable section for at least one of insertion or removal of the canister; a cold deck nozzle assembly, the cartridge assembly being connected to the cold deck nozzle assembly through a one-way check valve and configured to inject thermoset elastomer from the canister into the cold deck nozzle assembly, the cold deck nozzle assembly comprising a manifold block with an internal passageway in fluid communication with the cartridge assembly and adapted to receive thermoset elastomer therefrom, and a cold deck nozzle in fluid communication with the internal passageway, the cartridge assembly further comprises a mechanism for driving the thermoset elastomer into the cold deck nozzle assembly; and a micro plunger injection assembly connected directly to the cold deck nozzle assembly, the micro plunger injection assembly comprising a housing and a plunger moveable therein, the plunger configured to drive the thermoset elastomer through the internal passageway of the cold deck nozzle assembly and the cold deck nozzle, wherein the thermoset elastomer displacement for a single shot is substantially equal to the desired shot weight.
