An excellent molded article having a fine and spherical tixotropic structure is mass-produced automatically, continuously, conveniently and easily at a low production cost without using a conventional mechanical agitation method and electromagnetic agitation method. An apparatus for producing a metal which is semimolten-molded and has a uniform temperature distribution and in which fine primary crystals are dispersed in the liquid phase, comprises a molten metal feeding section which comprises a melting furnace for melting and holding a metal and a molten metal feeder for drawing up a molten metal inside the melting furnace, adjusting its temperature to a predetermined temperature and then supplying it to a container, a nucleus producing section for producing crystal nuclei in the molten metal supplied from the feeder into the container, a crystal growing section for cooling the metal obtained from the nucleus producing section to a molding temperature at which the metal is in a solid-liquid coexisting state to a target molding temperature range, a container heating section for adjusting the temperature of an empty container, a container preparation section for discharging the semimolten metal by turning upside down the container and then cleaning the inner surface of the container, and a container conveyor section equipped with an automation apparatus inclusive of a robot for conveying and loading the semimolten metal obtained from the nucleus producing section into an injection sleeve of a molding machine.
