A method for producing a motor vehicle rim made of aluminum or an aluminum alloy for a motor vehicle wheel. The motor vehicle rim has a rim base delimited on opposite sides by an outer horn and an inner horn, a hub with a central recess and a hole circle and a rim center connecting the rim base and the hub to one another and acting eccentrically on the rim base in longitudinal section. The motor vehicle rim is produced in one piece and continuously in a casting mold by vacuum die casting of a casting material, wherein the motor vehicle rim has a small wall thickness of at most 15 mm at least in some regions and/or a curvature with a small radius of curvature of at most 4 mm.

A method for producing a motor vehicle rim made of an aluminum alloy for a wheel of a motor vehicle, the motor vehicle rim having a rim base limited on opposite sides by an outer horn and an inner horn, a hub with a central recess and a hole circle, and a rim center connecting the rim base and the hub to one another. The motor vehicle rim is produced in one piece and continuously in a casting mold by die casting of a casting material, the casting material being the aluminum alloy.

A method for producing a cylindrical hollow body (20) made of aluminum, an aluminum alloy, or a light metal alloy, includes casting a hollow body (20) such that the hollow body (20) has an inner and an outer lateral surface (21, 22) and two axial end faces. The method also includes, during the casting process, making at least one defined notch (35, 35′) into one or more of the inner lateral surface (21), the outer lateral surface (22), and the two axial end faces.

A method for producing a vehicle wheel from a light metal material is disclosed herein. The light metal material is introduced in liquid form into a mold cavity of a casting mold and pressurized casting is then used to produce the vehicle wheel. The casting mold is temperature-controlled, where different regions of the casting mold are maintained at different temperatures. An apparatus that includes the disclosed casting mold is also described herein.

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 for producing a one-piece cast vehicle wheel, the wheel having at least one hub portion connected to a wheel rim via at least one spoke oriented in the radial direction of the wheel, in which at least one lost core is inserted in a molding of the casting machine, the one-piece vehicle wheel is cast, and the lost core is removed from the cast vehicle wheel and thereby forms at least one opening in the spoke. A one-piece cast vehicle wheel formed by the method is also provided.

A method for manufacturing a roll mantle or roll body for a roll line of a continuous casting apparatus that has a shaft includes casting a metal to form the roll mantle or roll body such that the roll mantle or roll body includes at least one internal channel. The roll mantle or roll body has a first end region, a second end region and a central region between the first end region and the second end region, the central region extending along at least 50% of a length of the roll mantle or roll body, and the internal channel may be formed in the central region. The internal channel may also include a pattern or projection.

The present disclosure belongs to the technical field of casting equipment, and provides a method and system for adjusting process parameters of a die-casting machine, and a storage medium. The method and the system can receive die wheel type, molten aluminum temperature, interruption time and defect information in real time, respond to the above information one by one according to a set response priority order, select die-casting process parameters, and automatically adjust different process parameters for different products and different working conditions, thereby realizing simultaneous control of multiple die-casting machines, replacing manual adjustment and improving product quality stability and production efficiency.
