Our Invention "ICS- Counter Gravity Casting" is 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 invented technology also includes a multiple metal sections configured such that adjacent metal sections mate to one another, the metal sections being separable from one another and the metal sections include recesses that form the mold cavities, and the mold includes a sprue and multiple runner passages. The invented technology is also 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 and the methods of casting bulk amorphous alloy articles or feedstock is described. The invented technology also includes the vacuum, counter gravity casting of molten metal includes a bottom drag member and a casting mold member thereon engaged together at a parting plane. The invented technology also a valve member is disposed adjacent the parting plane in an in gate to a mold cavity formed at least in part in the casting mold member and is movable between a valve seat on the bottom drag member and a stop surface on the casting mold member to permit filling of the mold cavity in counter gravity manner from an underlying molten metal pool when the bottom drag member is immersed therein and to prevent backflow of the molten metal from the mold cavity when the bottom drag member is withdrawn from the pool after mold filling and before solidification of the molten metal in the mold cavity. to vacuum j_00 to vacuum 108 vacuurn tube 106 cnnecor - 1 14 b 102 mold height adjust 1062 14neto 120 126 12614 122- 144 136 124 104 feed tube 134 molaten alloy 0gas 158 e1 feed 130 crucible height146 144D vacuum chamber FIG. 1 ILLUSTRATES AN EXEMPLARY COUNTER GRAVITY CASTING APPARATUS ACCORDING TO AN EXEMPLARY EMBODIMENT.
