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.

The prevent invention provides a mold core assembly and a slidable element. The mold core assembly is used to form a partial shape of the sliding element applied to a zipper head assembly structure. The mold core assembly includes a first mold core structure and a second mold core structure. The first mold core structure has two first lateral structure bodies and a first middle structure body disposed between the two first lateral structure bodies. The first middle structure body has two first extending portions. The second mold core structure has two second lateral structure bodies and a second middle structure body disposed between the two second lateral structure bodies. The second middle structure body has two second extending portions corresponding to each other. Each first extending portion has a nonuniform thickness, and each second extending portion has a nonuniform thickness.

A method for manufacturing a blade with a first portion and a second portion, the method includes forming the first portion that includes forming a model of the first portion from removable material, forming a first shell mould from the model of the first portion, and forming the single-crystal or columnar first portion m a first metal alloy in the first shell mould from a single-crystal seed, and forming the second portion in which the second portion is formed on the first portion, and in which the first portion and the second portion are made from different materials, the second portion being polycrystalline and formed from a second metal alloy. The blade includes a single-crystal or columnar first portion made from a first metal alloy and a polycrystalline second portion made from the second metal alloy different from the first metal alloy.

The invention relates to an electrotechnical coil, to a method for producing same, and to an electromagnet or an electric machine comprising at least one such coil. The aim of the invention is to produce and use an electrotechnical coil for achieving an increased slot fill factor reliably and easily in a reproducible and economical manner. This is achieved in that the method according to the invention has the steps: step A: casting an electrotechnical coil with at least one winding which runs about a coil axis; and step B: shaping the coil, thereby changing the cross-section Q, Q′ of the at least one winding, such that the centroid FS, FS′ of the cross-section Q, Q′ of the at least one winding is displaced at least partly in the radial direction R relative to the coil axis A.

An aluminum casting method is for pouring an aluminum molten metal (12) pumped up by an electromagnetic pump (20) into a die (50). A thickness of a powder demolding agent applied to the die (50) is set to be thinner than that of a demolding agent for a gravity die casting. A temperature of the die immediately before the molten metal is poured is controlled so as to fall within a range that is between 110° C. to 250° C. A temperature of the molten metal when poured is controlled to be a value obtained by adding 20° C. to 55° C. to a liquidus-line temperature of the aluminum.

Methods for creating a cast component, along with the resulting cast components, are provided. The method may include heating a mold having a cavity therein; supplying a first molten metal material into the cavity of the mold such that the first molten metal material is directed to a first portion of the cavity of the mold; supplying a second molten metal material into the cavity of the mold such that the second molten metal material is directed to a second portion of the cavity of the mold, wherein the first molten metal material is compositionally different than the second molten metal material; and thereafter, allowing the first molten metal material and the second molten metal material to form the cast component.

Cast components are provided that include a first section comprising a first metal material and having first grains with a first average grain size and a second section comprising a second metal material and having second grains with a second average grain size.
