ABSTRACT:
The apparatus for casting comprises a pressure vessel and a device for pressurizing the vessel. The pressurizing device is in fluidic connection with the vessel. The apparatus is also comprised of a chamber disposed in the pressure vessel within which material is melted. There is a mold adapted to contain a preform disposed in the vessel and in fluidic connection with the chamber by a passage such that melted material in the chamber can be forced down into the mold through the passage as the pressurizing device pressurizes the vessel. A heating device is disposed in the vessel. There is also a device for directionally solidifying the material in the mold. Additionally, there is a method comprising the steps of loading the pressure vessel by disposing a material within the chamber whereby the material is in fluidic connection with the mold adapted to contain a preform through the passage. The passage has a filter disposed therein. Next, there is the step of melting the material in the chamber whereby the melted material fluidically seals the passage thereby isolating the interior of the mold from the interior of the vessel. The filter prevents melted material from entering the interior of the mold.
