An apparatus and a process for producing forged components composed of TiAl alloys, wherein a melt of a TiAl alloy is provided and is cast by horizontal centrifugal casting so as to produce at least one semifinished TiAl cast part and the semifinished TiAl cast part is converted by forging into a forged TiAl part.

The invention relates to a method of producing elongate metal strands or fibres with a crucible, the method comprising the steps of; directing molten metal through a nozzle having a nozzle direction in a deposition direction at a regulated pressure difference between the inside and the outside of the crucible; depositing said molten metal from said nozzle on a rotating planar surface having an axis of rotation; entraining said molten metal in one plane via said rotating planar surface to form elongate metal strands, wherein said rotating surface is aligned at an alignment angle, to the deposition direction during the entraining of the molten metal; cooling said elongate metal strands to form solidified metal strands; and guiding said metal strands to collecting means to collect the solidified metal strands formed on the rotating planar surface.

A system and method for moulding metal parts having a first metal structure (4) which is integrally attached to a rotating machine, where said structure (4) is associated with a cover (3) and a plurality of fastening elements (1, 2), and where, in turn, the structure (4) is integrally attached to a cylindrical metal die (5) containing a ceramic mould (7) and hardened sand (6) for filling the die (5).

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.

Disclosed herein is a casting cluster for casting a body of a golf club head made of titanium or a titanium alloy. The casting cluster comprises a receptor and a plurality of runners coupled to the receptor and configured to receive molten metal from the receptor. The casting cluster also includes at least twenty-eight main gates. At least two of the main gates are coupled to each of the runners and each main gate is configured to receive molten metal from a corresponding one of the plurality of runners. The casting cluster further comprises at least twenty-eight molds. Each mold of the at least twenty-eight molds is configured to receive molten metal from a corresponding one of the main gates and to cast a body of a golf club head that has a volume of at least 100 cm.sup.3.

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 casting mold supporting structure is provided herein which includes a support roller for supporting a part of a casting mold that is used in centrifugal casting. The casting mold has a supported surface (that is, a side surface of an end portion of the casting mold which end portion has a circular truncated cone shape) at which the casting mold is supported by the support roller. The supported surface is inclined with respect to a rotation axis of the casting mold.

Various enhanced features are provided for centrifugal casting apparatuses, rotatable assemblies, and molds for casting products from molten material. These enhanced features include, among others, tapered gate portions positioned adjacent to the cavities of a mold, extended and shared gating systems, and detachable mold structures for modifying the thermodynamic characteristics and behavior of molds during casting operations.
