PROBLEM TO BE SOLVED: To provide a molding method and a molding apparatus for semi-solid metal, wherein voids and an eutectic, which are generated in a molding formed from semi-solid metal and which are caused by a cold shut at the downstream side of a hole, are reduced. SOLUTION: The molding method is a semi-solid die-casting method wherein a molding is formed by charging and solidifying semi-solid metal (slurry) 1 in a cavity 5. When charging the slurry 1 in the cavity 5, a movable pin 10 forming a hole in the molding is retracted to a retracting position so that the slurry 1 smoothly flows. After the surface layer part 1a of the slurry 1 passes the movable pin 10, the movable pin 10 is advanced to a hole-forming position before charging the slurry 1 is completed.
