Abstract: A method for casting a part, that includes the steps of: introducing a mold into a first housing; engaging the first housing with a second housing to define a second chamber; melting an ingot within the furnace; reducing pressure within the second chamber to a first predetermined pressure; pouring at least a portion of the melted ingot into the mold; adding an gas to the second chamber to raise the pressure to a second predetermined pressure; moving the mold such that it is engaged with the means for cooling; and solidifying the liquid metal within the mold.

Abstract: A casting assembly includes a core body extending along an axial direction between a first end and a second end, the core body having a core interior surface and a core exterior surface, with the core exterior surface shaping a part surface of a cast part. The core interior surface at least partially bounds a hollow cavity. The casting assembly also includes a shell body extending along the axial direction and having a first shell surface and a second shell surface, with at least a portion of the second shell surface facing the exterior surface of the core body.

Inventor： Brian David Przeslawski , Douglas G. Konitzer
Abstract: A method for producing a cast component is provided. The method includes attaching a ceramic mold to a seed crystal body, the ceramic mold including a cavity defining the shape of the cast component and a seed crystal body interface having a complementary shape to the seed crystal body such that the seed crystal body may be capable of supporting the ceramic mold in a casting oven. The method also includes pouring a liquid metal into the mold such that the crystal seed portion contributes to controlled crystallization of the cast component.

Abstract: An apparatus for casting a part that includes a first housing, a second housing, a handling system and a cooling apparatus. The first housing defines a first chamber. The first chamber is configured to receive a melt heater and a mold heater. The second housing is configured to move between a first position and a second position such that when the second housing is in the first position, the first housing is open such that a mold can be inserted therein and when the second housing is in the second position, the second housing and the first housing define a second chamber. The cooling apparatus is configured to be positioned within the second chamber.
