PURPOSE: To increase the production efficiency and to prevent the defect generation by arranging by adjoining the mixture of a sinter metal powder and synthetic resin binder to the main body forming part and by depositing the metallic sintered body to the main body simultaneously with the main body casting.
CONSTITUTION: A sintering metal is formed by mixing the wear resistant high melting point metallic powder of Mo, WC, etc., and the low melting point alloy powder of Ni, etc., and further formed in a sheet like mixture (m) by adding synthetic resin binder as well. The sheet like mixture (m) is adhered to the stepping part 131, 132 of the main body 11 forming part and a molten metal is poured into a gate 14 in the shell die 10 composed of the upper die 8 and lower die 9. In this case, the metal sintering body is deposited to the main body 2 by a liquid phase sintering phenomenon with the synthetic resin binder being subjected to thermal decomposition simultaneously with the main body 2 being cast to the forming part 11. The production efficiency is increased due to the casting and sintering being completed in one stage and the defect generation can be prevented as well due to the gas being completely exhausted.
