A vehicle chassis includes a pair of rear side members disposed on a rear floor of a vehicle so as to extend in a longitudinal direction of the vehicle while being spaced apart in a transverse direction of the vehicle. The pair of rear side members is manufactured in a casting process A cross member is configured to extend in the transverse direction of the vehicle and is manufactured in an extrusion process. The cross member is inserted into a mold when the rear side members are cast such that both ends of the cross member are connected to the rear side members disposed on both sides, respectively.

A film forming method forms a coating film on a workpiece having at least two film-deposited portions which are not continuous with each other by moving a nozzle of a cold spray device relative to each other along a continuous movement trajectory. The movement trajectory includes at least two trajectories corresponding to the film-deposited portions and a connecting trajectory linking the trajectories of the film-deposited portions. The film-deposited portions are formed by continuously spraying a raw material powder from the nozzle by cold spraying to form a coating film on each of the plurality of film-deposited portions. A turnback point of the spraying is set on the connecting trajectory where a relative speed between the workpiece and the nozzle decreases in the movement trajectory.

There is provided a method for producing a metal matrix composite by which a metal matrix composite having a near-net shape of high dimensional accuracy and having a high reinforcing material volume ratio (Vf %) can easily be obtained. The method for producing a metal matrix composite is such that in a production method for obtaining a metal matrix composite, wherein a matrix material, such as a pure metal, and a reinforcing material different from the matrix material are compounded, a material containing the reinforcing material is filled in a metal mold having a near-net-shaped space (recessed portion) formed inside thereof to form, in the metal mold, a reinforcing material-molded or filled body having pores inside thereof, the metal mold having the reinforcing material-molded or filled body formed is preheated in a preheating step, the preheated metal mold in a state where the reinforcing material-molded or filled body is put therein is installed in an outer shell metal mold for casting a composite, the pores of the reinforcing material-molded or filled body in the metal mold are impregnated or filled with the molten matrix material to perform a casting step of compounding the matrix material and the reinforcing material, and in a series of the steps of the molding step of molding the reinforcing material-molded or filled body, the preheating step, and the casting step, the same metal mold is used.

A casting component, in particular for a combustion engine of a motor vehicle, having at least one cavity formed by a lost casting core, where a porous metal body molded in the cavity is formed by the casting core, is disclosed. Furthermore, the casting core for such a casting component is formed by casting a metal, in particular an aluminum alloy, together with a salt. Finally, a method for the production of such a casting component or of such a casting core is also disclosed.

A mold assembly for use in forming a component having an outer wall of a predetermined thickness includes a mold and a jacketed core. The jacketed core includes a jacket that includes a first jacket outer wall coupled against an interior wall of the mold, a second jacket outer wall positioned interiorly from the first jacket outer wall, and at least one jacketed cavity defined therebetween. The at least one jacketed cavity is configured to receive a molten component material therein. The jacketed core also includes a core positioned interiorly from the second jacket outer wall. The core includes a perimeter coupled against the second jacket outer wall. The jacket separates the perimeter from the interior wall by the predetermined thickness, such that the outer wall is formable between the perimeter and the interior wall.

The invention relates to a method for producing a cast metal part, in particular a housing of an electric motor stator, a housing for components of power electronics, and a battery tray or a battery housing, having the following steps: producing a cooling channel, introducing the cooling channel into a casting tool, filling the casting tool with a casting material, and molding the cast part. According to the invention, the production of the cooling channel includes a roll welding step.

The present disclosure relates to a wear part having high wear resistance and strength and a method of making the same. The wear part is composed of a compound body of cemented carbide particles cast with a low-carbon steel alloy. The low-carbon steel alloy has a carbon content corresponding to a carbon equivalent Ceq=wt % C+0.3(wt % Si+wt % P) of about 0.1 to about 1.5 weight %. The wear part could include a body with a plurality of inserts of cemented carbide particles cast into a low-carbon steel alloy disposed in the body. Each of the plurality of cemented carbide inserts are coated with at least one layer of oxidation protection/chemical resistant material. The plurality of inserts are directly fixed onto a mold corresponding to the shape of the wear part. The cemented carbide inserts are then encapsulated with the molten low-carbon steel alloy to cast the cemented carbide inserts with the low-carbon steel alloy.

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

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.

Some embodiments provide methods and systems for casting articles. One example of a method includes providing and positioning a thermal blanket within a mold cavity and then introducing a molten material into the mold cavity and into contact with the thermal blanket. The method allows the molten material to remain in a molten state during a dwell time that extends from the introduction of the molten material at least until the mold cavity is filled. In another example, a method of using a thermal blanket includes keeping a molten material in a molten state during a dwell time extending from first introduction of the molten material until pressurization. Systems including a variety of mold types, one or more thermal blankets, and in some cases preforms and/or inserts are also provided. Also described is a novel thermal blanket and method of manufacturing the same.
