Alloy Steel Vacuum Castings

Alloy steel castings by vacuum casting process play an important role in diverse industrial areas. Vacuum-sealed molding casting process, the V-process casting for short, is widely used to make iron and steel castings with relatively thin wall, high precision and smooth surface. However, the vacuum casting process cannot be used to pour metal castings with very small wall thickness, because the liquid metal filling in a mold cavity relies on only the static pressure head in the V-process. Moreover, the V process cannot produce castings that require very high dimension accuracy due to the restricted compressive strength of the mold
