A system for casting a length of a pole of a tubular shape with molten metal. The system comprises a crucible for containing the molten metal; a pouring spout fluidly connected to the crucible; and a plunger for plunging in the crucible to increase level of the molten metal in the crucible and thereby forcing a flow of the molten metal from the crucible to the pouring spout. The system further comprises a casting ring for receiving the molten metal poured out of the pouring spout; a motor for rotating the casting ring; a cooling assembly for cooling the molten metal; and a pulling assembly for pulling the pole out of and away from the casting ring as the molten metal solidifies.

A centrifugal casting apparatus is provided. The centrifugal casting apparatus includes an upper mold machined to have an inner contour used to form an upper side surface of a casting, and a lower mold machined to have an inner contour used to form a lower side surface of the casting. An upper motor provides power to rotate the upper mold and a lower motor provides power to rotate the lower mold. The upper motor and the lower motor are operated independently of each other.

A method for producing cast items in a casting method, wherein a charge of a conductive material is introduced into the sphere of influence of at least one alternating electromagnetic field, so that the charge is kept in a levitating state. The melt is poured into moulds in order to produce turbine blades, prostheses or turbocharger impellers.

A vacuum centrifugal casting apparatus includes an upper mold having an upper vacuum hole communicating with both a cavity and a space over the upper mold, a lower mold including a lower vacuum hole corresponding to the upper vacuum hole, the lower vacuum hole communicating with both the cavity and a space under the lower mold, a motor configured to rotate the upper mold and the lower mold, a vacuum retaining member having an outer diameter corresponding to the upper vacuum hole, with a molten metal injection hole formed in an upper end of the vacuum retaining member, and a vacuum pump configured to be operated by the motor, and including an inlet communicating with the lower vacuum hole, and an outlet formed to exhaust drawn air.
