Abstract
A process for making molds which do not generate toxic gas in pouring a molten metal into the molds equipped with casting cores or the like even when the binder contained therein decomposes and which are excellent in disintegration characteristics after casting. The process includes mixing a particulate aggregate with one or more water-soluble binders, a surfactant, a crosslinking agent and water under stirring and foaming to prepare a foamed aggregate mixture, charging the foamed aggregate mixture into a mold-foaming cavity, solidifying the charged mixture by evaporating the water contained in the mixture to form a mold, and taking the mold out of the cavity.
