Abstract

A controlling member (a controlling pin ) is inserted through an insertion hole of a mold and projected into a cavity . After a pipe P as an insert member is arranged at a predetermined position in the cavity , the pipe P is held in the cavity by inserting a tip of the controlling pin into a hole h of the pipe P at the end p , or by inserting the end p of the pipe P into a cave of the controlling member. A molten aluminum alloy is then poured through a gate into the cavity under such the condition, to enclose the pipe P with the aluminum alloy. Dislocation of the pipe P caused by kinetic and thermal energies of the poured aluminum alloy is suppressed by the controlling pin or block at the end p . Since the enclosed pipe P has its end p opened at a predetermined position, a cast product obtained in this way can be used as a brake caliper or the like having an inner hydraulic circuit.
