PROBLEM TO BE SOLVED: To embody a casting method which compounds a light alloy material, such as aluminum alloy, by a material for composition, such as perforated metal, without the need for a high-pressure casting method requiring costly and large-sized equipment. SOLUTION: The material 7 for composition having pares is held in a casting mold 11 and the melt of the light alloy material is injected into this casting mold 11. The inside of the casting mold 11 is thereafter pressurized by gas in the state of closing the sprue 22 of the casting mold 11, by the pares of the material 7 for composition are impregnated and packed with the molten metal. The composite part where the light alloy material and the material 7 for composition is compounded is thus formed. |
