An apparatus (2) for the impregnation of metal castings including an impregnation chamber (11) having an open end; a movable assembly (2) comprising a cover (20) for closing the open end of the impregnation chamber, a casting carrier (21), carrier transport means (22) for raising and lowering the casting carrier relative to the cover, and carrier rotating means (23); and transport means (24) for raising and lowering the movable assembly relative to the open end of the impregnation chamber. The impregnation chamber is partially filled with liquid sealant (30). The apparatus is operated to position the carrier in the impregnation chamber above the liquid sealant therein and develop a vacuum in the chamber, submerge the carrier (and castings therein) in the sealant, and then raise the carrier above the sealant level and rotate carrier to spin-off excess liquid sealant; the movable assembly is thereafter raised to unload impregnated castings.
