Abstract: 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.

Abstract: A method for producing an automobile rim made of aluminum or an aluminum alloy for a wheel of an automobile, the automobile rim having a rim well delimited on opposite sides by an outer flange and an inner flange, a hub with a center recess and a bolt hole circle as well as a rim center connecting the rim well and the hub with one another. The automobile rim is produced in one piece and continuously in a casting mold by die casting of a casting material. The automobile rim is formed during the die casting with at least one air conveying element for conveying air in the axial direction with respect to a longitudinal center axis of the automobile rim relative to an imaginary plane perpendicular to the longitudinal center axis and/or at least one surface enlargement element extending in the circumferential direction along a circular line.

Abstract: 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.

Abstract: A method for producing a motor car rim made of aluminum or an aluminum alloy for a wheel of a motor vehicle. The motor car rim has a rim well delimited on opposite sides by an outer flange and an inner flange, a hub with a center recess and a pitch circle diameter, as well as a rim center connecting the rim well and the hub to one another and engaging the rim well off-center in the longitudinal section. The rim center is formed with several spokes spaced apart from one another in the circumferential direction as relates to a center longitudinal axis of the motor car rim.

Abstract: A method for producing an automobile rim made of aluminum or an aluminum alloy for a wheel of an automobile, the automobile rim having a rim bed bounded on opposite sides by an outer flange and an inner flange, a hub with a center recess and a bolt circle, as well as a rim center connecting the rim bed and the hub to one another, the rim center being designed with a plurality of spokes spaced apart in the circumferential direction with respect to the longitudinal center axis of the automobile rim. The automobile rim is produced in one piece and continuously in a casting mold by die casting of a casting material, wherein the automobile rim has, at least in some areas, a low wall thickness not exceeding 15 mm.

Abstract: 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.

Abstract: A method for producing a die-cast component and a die-cast component that is produced therewith. According to the invention, an outstanding punch riveting suitability is achieved if the die-cast component has a temperable aluminum alloy with the following alloying components: from 5.0 to 9.0 wt % silicon (Si), from 0.25 to 0.5 wt % magnesium (Mg), and residual aluminum as well as inevitable production-related impurities, containing at most 0.05 wt % of each and at most 0.15 wt % collectively, wherein the die-cast component has a yield strength (Rp0.2) of greater than 190 MPa and an elongation at break (A5) of greater than or equal to 7% and the uniform elongation (Ag) and necking elongation (Az) satisfy the condition Az?Ag/2.
