Method of and apparatus for producing light alloy composite member

摘要

A porous composite forming material is held in a cavity of a casting mold, and molten light alloy is poured into the cavity of the casting mold through a gate. Then a gas pressure is applied to the cavity in the casting mold with the cavity closed, thereby impregnating the pores of the porous composite forming material with the molten light alloy and forming a composite portion formed of a composite material of the light alloy and the composite forming material.
