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.
Claims21
A method for casting a part, the method comprising:
- introducing a mold into a first housing that defines a first chamber, wherein the first housing is spaced away from a second housing that defines a second chamber, and the first and second housings are exposed to the atmosphere;
- moving the second housing to engage the first housing with the second housing to cooperatively define a closed third chamber that encompasses the first and second chambers that together define an open volume within the first and second housings, wherein the third chamber is closed to the atmosphere and is configured to function both as a melting chamber and a mold chamber;
- melting, via the melting chamber, an ingot within the second chamber to form liquid metal;
- reducing pressure within the second chamber to a first predetermined pressure;
- pouring at least a portion of the melted ingot into the mold of the mold chamber;
- adding a gas to the second chamber to raise the pressure to a second predetermined pressure;
- moving the mold such that it is engaged with a means for cooling;
- and
- solidifying the liquid metal within the mold.
