FIELD: foundry, namely manufacture of precise complex-shape castings.
SUBSTANCE: method comprises steps of pouring doze of melt in squeezing chamber; squeezing melt by action of mechanical pressure from chamber to casting mold; creating gas counter pressure in casting mold at initial time moment of melt penetration into it; after filling cavity of casting mold with melt penetration of melt in top, releasing pressure; sustaining gas pressure until termination of casting process. Apparatus for casting by squeezing includes squeezing chamber and casting mold arranged in sleeve with cover. Sleeve is movable in horizontal direction and it is mounted in guides joined with cover. Cover is fixed and it is provided with clamps for forcing sleeve.
EFFECT: possibility for elimination of mechanical burning and warping of castings, improved mechanical properties of castings, simplified process for pouring melt to squeezing chamber, less loss of yield.
