A method of forming a casting with a flow passage may include filling a tubular pipe with a filler to form a smart core; inserting the smart core into a mold having a cavity corresponding to a shape of the casting to be formed; injecting a molten metal into the cavity through a casting process; and removing the filler from the smart core, wherein a hardness of the tubular pipe is 70 Hv or more.

A method of forming a casting with a flow passage may include forming a core obtained by filling a tubular pipe with a filler; inserting the core into a mold having a cavity corresponding to a shape of the casting to be formed; performing a casting process by injecting molten metal into the cavity; and removing the filler from the core, wherein the casting process is performed through a high-pressure casting process.

A vacuum centrifugal casting apparatus includes an upper mold having an upper vacuum hole communicating with both a cavity and a space over the upper mold, a lower mold including a lower vacuum hole corresponding to the upper vacuum hole, the lower vacuum hole communicating with both the cavity and a space under the lower mold, a motor configured to rotate the upper mold and the lower mold, a vacuum retaining member having an outer diameter corresponding to the upper vacuum hole, with a molten metal injection hole formed in an upper end of the vacuum retaining member, and a vacuum pump configured to be operated by the motor, and including an inlet communicating with the lower vacuum hole, and an outlet formed to exhaust drawn air.
