摘要： A core structure for a providing a cooling passage in a gas turbine engine includes a core body that has a first cooling passage core. The first cooling passage core has a first width in a chord-wise direction near a first wall. A second width in the chord-wise direction near a second wall. A third width in the chord-wise direction between the first and second walls. The third width being smaller than the first and second widths to form an hourglass shape.

摘要： A hybrid method of casting a metal product is disclosed. The method includes obtaining a product design, creating a mold insert based on the product design, creating a mold base based on the product design, assembling the mold insert with the mold base to form an assembled mold, casting the metal product with the assembled mold, and post-processing the metal product. In some embodiments, creating a mold insert includes generating printing instructions for a mold insert based on the product design and printing a mold insert configured to mate with a product mold (for example, a mold produced by traditional sand molding processes) based on the printing instructions.

摘要： Methods and systems for creating a mold for a cast memorialization product are described herein. In a process for creating a mold, a three-dimensional (3D) model of a product design is generated. The product design includes customized features for a memorialization product. A mold design is generated based upon the 3D model of the product design. Printing instructions for creating the mold are generated and accessed by a processing device. The mold is created according to the printing instructions. A product, such as a bronze memorialization product, can be cast using the mold.

摘要： 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.

摘要： A process manufactures a metal part for a turbomachine that includes first and second metal materials with different chemical compositions. The process includes the steps of obtaining an element of which at least a first metallic part is made of the first metallic material and placing the element in a first mold and pouring wax into the mold to at least partially cover the element. The first mold has an impression corresponding to at least part of an external surface of the metal part. The process further includes obtaining an assembly by removing the first mold and making a shell mold with a first ceramic around the assembly. The process also includes removing the wax from the shell mold and pouring the second metal material into the shell mold in place of the wax, and removing any ceramics present in the assembly.

摘要： A mold package for forming a cast device such as an engine block is described. The mold package includes a profiled chill and a mold core assembly that is disposed on the profiled chill. The mold core assembly defines a plurality of bulkheads of the engine block. The profiled chill includes a first chill portion having a second chill portion and a plurality of third chill portions arranged thereon, wherein the second chill portion is a semicylindrical element. The third chill portions are arranged to be adjacent to the plurality of bulkheads of the engine block.

摘要： A meshed shell and a sandblasting method are provided. The meshed shell includes a first end portion, a second end portion opposite to the first end portion, a first annular portion, a second annular portion connected to the first annular portion, a first mesh portion between the first end portion and the first annular portion and a second mesh portion between the second end portion and the second annular portion. The weights of the first end portion and the second end portion are the same. A maximum inner diameter of the mesh of the first and second mesh portions is smaller than a penetration size of the component. Both of the sum of the weights of the first and second end portions and the sum of the weights of the first and second annular portions are greater than the sum of the weights of the first and second mesh portions.

摘要： A casting mould for casting complex-shaped castings from a molten metal. The casting mould has a mould cavity forming the casting and a delivery system that delivers molten metal into the mould cavity. The delivery system includes a sprue, a runner connected to the sprue and a feeder system connected to the runner. The mould cavity is connected to the feeder system or the runner via connections. When seen in the flow direction of the molten metal flowing from the sprue into the runner during the casting operation, the runner has a branch directed away from the sprue along the feeder system and has a directed-back branch adjoining the directed-away branch and guided along the feeder system in the opposite direction to the directed-away branch. The feeder system is connected to both the directed-away branch and the directed-back branch via two or more gates distributed along the respective branch.
