A casting system includes a casting for an automobile vehicle having an interior section. Multiple central portions are individually positioned in one of multiple areas of the interior section completely encapsulated by a metal of the casting. An insert member is positioned in individual ones of the multiple central portions, the insert member having a higher melting point than a melting point of a metal of the casting the insert member displaces.

A method of fabricating a ceramic turbine blade, the method includes selective melting on a powder bed in order to obtain a blade mold cavity in a mold, a ceramic-based suspension is provided, the suspension is introduced into the blade mold cavity, the suspension is subjected to a gelation step in the mold cavity in order to obtain a blade suitable for being extracted from the mold cavity, and the blade is extracted from the mold cavity.

Methods for manufacturing a turbine nozzle are provided. A plurality of nozzle segments is formed. Each nozzle segment comprises an endwall ring portion with at least one vane. The plurality of nozzle segments are connected to an annular endwall forming a segmented annular endwall concentric to the annular endwall with the at least one vane of each nozzle segment extending between the segmented annular endwall and the annular endwall.

The present disclosure relates to a brake disc including a braking part having a circular plate shape having a hollow portion and a plurality of coupling portions protruding and extending from an inner diameter surface thereof, and a hat part disposed in the hollow portion and having a plurality of insertion portions protruding laterally, in which the plurality of coupling portions is respectively coupled to the plurality of insertion portions, and the coupling portion of the braking part and the insertion portion of the hat part are joined to only one of an outboard portion or an inboard portion of the braking part. According to the present disclosure, it is possible to reduce noise occurring at a position at which the hat part and the braking part are coupled to each other and improve cooling performance.

A brake component for a motor vehicle may include a body and at least one cable positioned within the body. The at least one cable may include a plurality of wires positioned relative to one another, each of the plurality of wires having a surface in sliding contact with surfaces of adjacent wires of the plurality of wires. During braking of the motor vehicle, sliding movement of the surfaces of the plurality of wires relative to each other may dampen a resonant frequency of the component.

A rotor of a rotary dynamoelectric machine incudes a magnetically conductive body, having substantially axially running slots distributed around the circumference. A squirrel cage includes electrical conductors which are arranged in the slots. The electrical conductors are electrically contacted at the two end faces of the rotor by short-circuit rings. The magnetically conductive body includes a base body and at least two further additional bodies, which axially adjoin the base body. A first one of the at least two additional bodies directly axially adjoins the end face of the base body, and a second one of the at least two additional bodies and optionally any further additional body axially adjoin the first additional body. The slots have radially exposed slot portions in the axial end regions of the rotor such that the conductors can be moved radially outward.

A method for manufacturing a golf club head having an embedded heterogeneous material includes preparing a shell mold having a cavity and a functional member embedded into the shell mold via an embedded portion, filling the cavity with a metal liquid to completely dip the non-embedded portion of the functional member in the metal liquid; breaking the shell mold to obtain a cast product, separating the golf club head cast member from the cast product to obtain a semi-finished golf club head having a casting material and a heterogeneous material, and pressing the casting material of the semi-finished golf club head to securely engage the casting material with the heterogeneous material. The functional member includes a non-embedded portion connected to the embedded portion and located in the cavity. The cast product includes a golf club head cast member.
