More Information
Summary:A counter gravity casting apparatus includes a reusable metal mold having a plurality of mold cavities, a feed tube configured to feed molten alloy into the mold, and a vacuum fitting configured to permit a vacuum to be applied to the mold. The mold includes multiple metal sections configured such that adjacent metal sections mate to one another, the metal sections being separable from one another. The metal sections include recesses that form the mold cavities, and the mold includes a sprue and multiple runner passages. The sprue is configured to receive molten alloy from the feed tube, and the multiple runner passages are configured to feed molten alloy from the sprue to the mold cavities. Methods of casting bulk amorphous alloy articles or feedstock is described.
