A modular spruing system apparatus contains a base section, a main sprue cone, a center rod, a plurality of trunk sections, a plurality of arm sections, and an end cap. The main sprue cone is mounted onto the base section. The center rod centrally traverses through the base section and the main sprue cone so that the user can design a spruing tree of desired height. A center rod receiving hole of each of the plurality of trunk sections allows the center rod to traverse through the plurality of trunk sections when removably attached to each other. Next, the plurality of arm sections is attached to the plurality of branch sections. The plurality of arm sections can be fixed or removably attached to the plurality of branch sections. When the desired height is reached, the plurality of trunk sections is fastened together with the end cap.

This filtration device 10 has a can body 20 having a reservoir 3 that connects to an opening 9 at the top, and a filtration unit 40 which is detachably installed in the reservoir. The filtration unit has a support plate 42, and filtration tubes 41 of bottomed cylindrical shape fastened to the support plate. The side wall 22 of the can body 20 has a protruding locking part 30 for installation of the filtration unit so that the filtration tubes are suspended from the support plate 42, with the openings 43 thereof facing upward. With the support plate 42 locked into the locking part 30, pressing members 70 for pressing the support plate 42 downward from the upper surface side in sections thereof lying towards the peripheral edge S in relation to the fastening locations of the filtration tubes 41 are deployed, making it possible for the support plate 42 to be fastened in clamped fashion by the locking part 30 and the pressing members 70.

The invention relates to a method of casting a metal alloy ingot. The method includes providing an on one side open-ended mould having a mould cavity, positioning the open-ended mould such that the mould opening points side-wards or down-wards, providing a casting container with an upwardly positioned aperture, and filling said casting container with molten metal for one casting operation. The method also includes locating the casting container below the mould while the mould opening points side-wards or down-wards, and rotating the mould together with the casting container to a position whereby the mould opening points upwards such that the molten metal is conveyed into the open-ended mould until a desired thickness. Molten metal in the open-ended mould is cooled directionally through its thickness where the solidification front remains substantially monoaxial.

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.

The present disclosure provides a method and system of casting an integral multi-way valve based on 3D printing, and belongs to the technical field of valve casting. The casting method and system determine, according to structural parameters of an integral multi-way valve to be cast, a plurality of ingates on a plurality of layers, a plurality of runners connecting the ingates on each layer, and a sprue connecting the plurality of runners, and an integral sand mold is printed by using the 3D printing technology to realize a multi-layer composite casting method and a corresponding casting system.

A riser sleeve (1) for using when pouring metals into a casting mould includes a riser body (2). The riser body (2) includes a riser cavity (3) for holding liquid metal and a riser opening (4) for joining the riser cavity (3) to a mould cavity of the casting mould during the casting process. The riser cavity (3) has a greater diameter than the diameter of the riser opening (4) in at least one portion, the riser body (2) is made of an insulating and/or exothermic riser material. The riser body (2) is formed as a single piece, the riser opening (4) defines an axis (5), and the riser cavity (3) is asymmetric to the axis (5).

A directional solidification casting method includes fluidly coupling a feed line conduit with a source of molten metal and with a directional solidification mold at a gating. The mold has an interior chamber with a shape of an object to be cast using directional solidification in a growth direction. The feed line conduit is fluidly coupled with the gating in a downward direction oriented at an angle that is closer to the growth direction of the mold than to another direction that is perpendicular to the growth direction of the mold. The method also includes positioning a downstream portion of the feed line conduit below the gating, directing the molten metal into the mold via the feed line conduit, and casting the object in the mold using directional solidification.
