Abstract
The present inventions provide a method for forming molds and a core which generates no gases with bad effects on the human bodies while the binders are heated. In particular, the present inventions provide a method for forming molds and a core comprising an aggregate material mixture consisting of granular aggregate materials, wherein the aqueous binders and water are foamed with stirring, filled into a space for forming molds, and caked with an evaporating water component. In an embodiment, molds can be further cured by adding cross linking agents before and after they are taken out from the space for forming. Further, an aggregate material mixture for forming molds used for the method for forming molds of the present inventions is provided.
