Abstract
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.
Claims5
A method of producing a vehicle wheel from a light metal material comprising introducing a light metal material in liquid form into a mold cavity of a casting mold via a gate region adjoining the mold cavity,
- wherein the vehicle wheel is produced using pressurized casting,
- wherein in areas in which the vehicle wheel has a smaller cross-section, the casting mold is tempered to higher temperatures, and in areas in which the vehicle wheel has a larger cross-section, the casting mold is tempered to lower temperatures,
- wherein the light metal material is in a liquid state and is introduced into the mold cavity at a casting piston speed of more than 5 m/s and a pressure of less than or equal to 100 bar, and
- wherein a ratio or modulus between the smallest cross-sectional area of the gate region and the volume of the mold cavity is at least 0.6 mm2/cm3, and,
- wherein the wall thickness of the vehicle wheel that is produced is less than or equal to 1 mm in at least some areas.
