Abstract
PURPOSE: To make a core shrink following to the cooling of a molten metal so as to prevent the development of crack, by interposing a corrugated cardboard between the facing sand and the backing sand of a furan casting mold made by using furan resin as a binder.
CONSTITUTION: In furan casting mold made by using furan resin as a binder, a cushion material such as corrugated cardboard 6 is interposed between the facing sand 5 and the backing sand 7 of a core 4. Hence the generation of crack is prevented unlike conventional method because the core 4 shrinks following to the cooling of the molten metal.
