Abstract
A method of high throughput pressure casting involving the steps of providing a mold vessel containing an infiltrant and a mold cavity; evacuating the mold cavity, and heating the infiltrant to form a molten infiltrant which isolates a reduced pressure in the mold cavity; transferring the mold vessel containing the molten infiltrant to a pressure vessel; applying pressure to the molten infiltrant to move it into the mold cavity; and cooling the molten infiltrant in the mold cavity to solidify the molten infiltrant. The mold cavity may contain a preform to produce a metal matrix composite.

A method of high throughput pressure casting comprising the steps of:
- (a) providing a mold vessel comprising a mold cavity and an infiltrant disposed adjacent to the mold cavity;
- (b) evacuating the mold cavity;
- (c) heating the infiltrant to form a molten infiltrant which isolates a reduced pressure in the mold cavity;
- (d) transferring the mold vessel comprising the molten infiltrant and the mold cavity having the reduced pressure isolated by the molten infiltrant to a pressure vessel;
- (e) applying pressure to the molten infiltrant to move the molten infiltrant into the mold cavity;
- and
- (f) cooling the molten infiltrant in the mold cavity to solidify the molten infiltrant.
