Made up of a step of preparing a map expressing a correlation between solid phase percentage and viscosity of a slurry-form semi-solid metal () for a given metal composition; a step of setting a target viscosity corresponding to a target solid phase percentage using this map; a viscosity measuring step of measuring the viscosity of a semi-solid metal in a vessel () while cooling it; and a step of carrying out cooling until this viscosity reaches the target viscosity, by these steps being carried out in from the preparation of the map expressing the correlation between solid phase percentage and viscosity of the semi-solid metal to the end of cooling of the semi-solid metal the solid phase percentage of the semi-solid metal is made to match the target solid phase percentage. Because the viscosity is detected, the affects of cooling rate changes and time can be eliminated, and it is possible to raise management accuracy of the solid phase percentage of the semi-solid metal much further than with related art management based on time.

Molding of slurry-form semi-solidified metal

An apparatus for producing a metal formed product comprises a molten metal-holding furnace; a semisolidified metal-producing mechanism; a cooling member-restoring mechanism arranged adjacent to the semisolidified metal-producing mechanism, for applying a restoring treatment so that chillers have a desired function; a forming machine for forming semisolidified metal to have a predetermined shape; and an articulated robot capable of transporting a crucible to the molten metal-holding furnace, the semisolidified metal-producing mechanism, and the forming machine. The semisolidified metal-producing mechanism includes first to third agitators. The cooling member-restoring mechanism includes first to third treating sections. These components are arranged in a direction of back and forth movement of the articulated robot. Accordingly, it is possible to efficiently obtain the metal formed product having a high quality.
