Abstract (en)

A supply apparatus supplies a semi-solid metal to a molding apparatus having an injection sleeve (31) formed with an opening portion (31A) and a plunger (32) provided progressively/regressively at an inner portion of the injection sleeve. The supply apparatus includes a crucible (11) in a shape of a cylinder containing a semi-solid metal, a carry arm (13) for grabbing to move the crucible (11), and a control apparatus for controlling the carry arm (13). The control apparatus inserts a front end portion (134) of a gutter (131) mounted to the crucible into (11) the opening portion (31A) of the injection sleeve (31) by a predetermined angle to inject the semi-solid metal to a side of a direction of advancing the plunger (32) more than at a position formed with the opening portion (31A) at inside of the injection sleeve (31).
