摘要：
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.
