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 forty 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 forty molds. Each mold of the at least forty molds is configured to receive molten metal from a corresponding one of the main gates and to cast a body of an iron-type golf club head.

A molding machine for molding material is provided. The machine includes a cavity to be filled with molten metal and a conduit system leading to the cavity, thus forming a system of interconnected hollow spaces. At least one pressure member is moveable in at least part of the conduit system. A centrifugal pump in fluid communication with a reservoir of molten metal is provided, the pump providing molten metal to the hollow space receiving the at least one pressure member.

A method of casting an annular member is provided. The method includes preparing a sand mold. The method further includes clamping the sand mold between at least two plates. The method further includes rotating the sand mold. The method further includes introducing molten cast material into the sand mold during rotation of the sand mold.

The present invention relates to a mould powder for coating cast moulds for reducing surface defects, such as pinholes, in ductile cast iron products. The mould powder comprises 10-99.5% by weight of a ferrosilicon alloy, 0.5-50% by weight of iron sulphide, and optionally 1-30% by weight of CaSi, and/or 1-10% by weight of CaF.sub.2. The invention further relates to a mould coating on and internal surface of a casting mould comprising 10-99.5% by weight of a ferrosilicon alloy, 0.5-50% by weight of iron sulphide, and optionally 1-30% by weight of CaSi, and/or 1-10% by weight of CaF.sub.2.

The invention relates to a rotary mold for centrifugal casting of an alloy. The mold comprises liners (135a) housed in hollow exoskeletons (137a). The exoskeletons retain the liners against the centrifugal force, during the casting, while the mold is spinning.

The invention concerns a unit comprising a mold (4) adapted to receive a molten metal alloy and the said metal alloy poured therein. The alloy is TiAl. The mold is rotational and comprises receiving recesses (135) made of steel, metal alloy and/or ceramic, and, at the location of a plurality of section planes each passing through the mold and the poured metal alloy, the mold has a surface heat capacity less than that of the poured metal alloy.

An aluminum alloy wheel for a vehicle is provided, which includes: a wheel central portion, a rim portion, and a plurality of radial elements, wherein the aluminum alloy wheel is processed by centrifugal casting and forging to form a central portion with a morphology exhibiting a grain size variation with decreasing gradient in a lateral direction from an inner side of the wheel central portion to an outer side thereof.

A fluid blow-out structure of a centrifugal casting device 1, for blowing out a fluid to inner surface of a rotating cylindrical mold 2, including: fluid application outer tube 5 inserted into the mold 2; movable mechanism 6 supporting a base end of the fluid application outer tube 5; outlet 8 through which the fluid is blown out, the outlet 8 provided at a leading end of the fluid application outer tube 5; fluid supply tube 9 inserted in the fluid application outer tube 5 and connected to the outlet 8; and guide mechanism 7 contacting an outer circumferential surface of the fluid application outer tube 5, and guides the fluid application outer tube 5 into and out of the mold 2. The fluid application outer tube 5 includes a resin hollow tube 10 and a metal tube 11 covering outer circumferential surface of the resin hollow tube 10.
