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 an automobile rim from aluminum or an aluminum alloy for a wheel of a motor vehicle. The automobile rim has a rim well delimited on opposite sides by an outer flange and an inner flange, a hub having a center recess and a bolt hole circle, and a rim center connecting the rim well and the hub to one another. The automobile rim is produced integrally and continuously in a casting mold by die casting of a casting material. After the introduction of the casting material into the casting mold, a volume of the casting mold is reduced for post-compaction of the casting material. The invention furthermore relates to a device for producing an automobile rim.

A method for manufacturing a vehicle wheel includes: a casting process of manufacturing the wheel in a one-piece body having a forming end and a temporary flange protruding at inner and outer sides of the wheel, respectively, wherein the one-piece body further includes a resonance chamber forming groove; a primary shape machining process of forming a stepped part at an outer circumferential side of the resonance chamber forming groove; a flow forming process of bending the forming end to be seated on the stepped part; a friction stir welding process of integrally bonding a portion where the forming end and the stepped part are in close contact with each other; a fine machining process of removing the temporary flange; and a sound-absorbing hole machining process of forming a sound-absorbing hole for communicating between the resonance chamber and an interior space of a tire in the forming end.

A hybrid wheel for vehicles that includes a unitary lug structure, with a mount face and a dish section of the lug structure extending therefrom. The lug structure is usually a cast aluminum alloy. A wheel structure including a high strength polymer encapsulates a portion of the lug structure dish section. Rim ring(s) are included in the wheel structure and are preferably made of a fiber reinforced high strength polymer.
