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 foundry core formed from a moulding sand, grains of which are bound together by a binder, and which is provided to form a cooling channel in an engine block for an internal combustion engine. The foundry core has a supporting section, two neck sections, which protrude from a lateral surface of the supporting section and are arranged at a distance from one another, and at least one bridge section which is held by the neck sections at a distance from the supporting section and a minimum thickness of which measured as the distance between its lateral surfaces is no more than 3 mm in an area which lies between the neck sections.

A method for demolding a casting from a casting mold having at least one casting core which images a passage opening in the casting connecting two outer sides of the casting and is produced from a molding material bound by a binder which decomposes under the influence of temperature, wherein the casting mold undergoes a heat treatment in a furnace for the demolding, during which it is heated to a temperature at which the binder loses its binding effect. In the furnace, hot gas is flowed through a passage formed in the casting core of the casting mold, the temperature of the hot gas corresponding at least to the temperature at which the binder of the molding material loses it binding effect such that the casting core decomposes into fragments or separate sand particles as a consequence of the influence of the hot gas.
