1. A casting machine for casting parts in a mold out of a metal using a metal feed stock, the machine comprising:
a. a thermally conductive block; b. a processing cylinder formed in said thermally conductive block, said processing cylinder having a processing chamber and opposite first and second end; c. a particulate feedstock feed housing to hold particular feedstock, said feed housing having an outlet connected to the first end of the processing cylinder being configured to transfer particulate feedstock from the feed housing to the first end of the processing cylinder; d. an injector cylinder formed in said thermally conductive block adjacent the processing cylinder, so as to have a common wall extending along said cylinders between said processing cylinder and said injection cylinder and thereby be thermally connected thereto; e. a shooting pot formed at one end of said injection cylinder and coupled to the second end of the processing cylinder by a passage within said thermally conductive block configured to permit feed stock to pass from the processing cylinder into the shooting pot; f. a nozzle coupled to the injector cylinder to transfer material from the shooting pot to the mold; g. a processing drive for driving the feed stock from the first end of the processing cylinder through the passage into the shooting pot; h. a heater thermally coupled to the thermally conductive block to transfer heat to the processing cylinder, and through said common wall to said injection cylinder and to the shooting pot, the heater and processing cylinder configured to supply heat to the feed stock such that the feed stock becomes progressively more liquid as it passes from the first to the second end of the processing cylinder; and i. an injector plunger coupled to an injector actuator for driving the plunger sufficiently to force the metal from the shooting pot through the nozzle and into the mold. |
