Abstract
In the mold-immersion type countergravity casting method, a resin-bonded particulate mold is formed in-situ in the vacuum chamber used to draw melt into the mold by: providing the chamber with a porous wall; positioning a gasifiable pattern in the chamber; embedding the pattern in a mass of mold-forming particulate containing a chemically curable precursor of the resin binder; and passing a curing gas through the porous wall and mass to cure the resin and unify the mass about the pattern. Thereafter, the mold is immersed in an underlying pool of molten metal and a vacuum drawn in the chamber to displace the pattern in the mold with metal.
