Abstract
A core-material container constituted of a container main body whose opening is covered with a sheet-like lid member made of an air-permeable material. In order to charge powder core material through a core-material charging inlet uniformly as well as densely, the charging operation of the core material is carried out in the following manner: housing the core material container in a housing space formed by a positioning guide and a plate member; releasing air from a suction outlet, thereby making the core-material charging inlet adhere around a nozzle; releasing air located inside a sealed space enclosed by an upper frame and a lower frame through an air outlet; and charging the core material through the nozzle while evacuating the core material container. Thus, the core material is uniformly charged by air flows caused by the air release, and the charge is densely carried out since air contained in the core material is removed.
