Master Alloy VIM systems are generally in the range of 1 to 10 tons and are characterized by their ability to pour many multiples of small diameter ingots configured on a mold car or turntable. Individually poured master alloy ingots are commonly as small as 73 mm (2 7/8″) and as large as 254 mm (10″) in diameter and generally about 1.2m (48″) tall. Gang poured ingots can be 50 mm (2″) and under, if desired.
