Abstract:
1. A vacuum mold comprising: at least a first plate and a second plate configured to mold amorphous alloy material therebetween so as to substantially eliminate exposure of the amorphous alloy material therebetween to oxygen and nitrogen; an enclosed ejector box positioned adjacent the at least first and the second plates that is configured to be vacuum sealed by vacuum pressure from at least one vacuum source; at least a first vacuum port and a second vacuum port both in communication with the at least one vacuum source that is configured to apply vacuum pressure to the at least first and second plates and the enclosed ejector box; an ejector mechanism in the enclosed ejector box configured to eject molded amorphous alloy material from between the at least first and second plates; a plurality of seals configured to be positioned between adjacent interfaces of the at least first plate, the second plate, and the enclosed ejector box, and wherein the at least one vacuum source is configured to apply vacuum pressure from the at least one vacuum source to the at least first and second plates and the enclosed ejector box in a first direction using the first vacuum port and in a second direction to the at least first and second plates and the enclosed ejector box using the second vacuum port.
