In the conventional apparatus for manufacturing aluminum parts as described above, first, the aluminum ingot is melted in the melting furnace, and then primary molding is performed by casting. Then, the scouring and gate portions, which are inevitably generated in the casting process, , Which is then cooled down to room temperature so that it can be cut at the cutter.

After the cooled molded article is cut in the cutter, it is put into a heating furnace and reheated to a temperature of about 400 DEG C, and then supplied to a forging apparatus and hot-forged to produce the final product.

As described above, according to the conventional manufacturing apparatus and method, in order to melt an aluminum ingot, it is heated at a high temperature in a melting furnace, then cooled, and reheated in a heating furnace again for hot forging. Is consumed.

In order to cut the tapping gate and the gate portion of the primary molded product, it takes a long time to cool to room temperature and again reheat at a high temperature in the heating furnace.
