ABSTRACT:
A plastic forming die for formation of outer surface is set on the inner surface of a cavity of a die. The forming die has a forming die body in a square barrel shape, and there are a lot of through holes provided between mount surfaces and inner side surfaces of the forming die body. Grooves communicating with the through holes are provided in the mount surfaces. When a molten metal is injected into the cavity, the through holes of the forming die body form outwardly projecting portions of a cast product. The forming die is then melted to be removed from the cast product.
