Title:
FORMATION OF SAND MOLD FOR CASTING
Document Type and Number:
Japanese Patent JP2001047189
Kind Code:
A
Abstract:
To improve the working condition, to reduce the gas defect in a casting and the production cost by recovering reusing the molding sand, and to improve the yield of the casting.
A mold part for molding by using organic base binder (ester- hardened phenol formaldehyde resin) and a mold part for casting by using inoganic base binder (water glass ester method), are adopted respectively as required. In this way, generation of a large quantity of the organic gas is prevented at pouring time of molten metal, and the mold excellent in collapsibility and reconditioning of the molding sand can be attained.
