Casting component useful as a structural component of a vehicle body, comprises a cavity, where the casting component is made of aluminum and/or aluminum alloy and is subjected to a heat treatment process after casting

摘要

The casting component (10a, 10b, 10c) comprises a cavity (12a, 12b, 12c), where the casting component is made of aluminum and/or aluminum alloy and is subjected to a heat treatment process after casting. A secondary mold (14b) of the casting component is designed as bead and influences the delay of the casting component during the heat treatment. The weight of the secondary mold is present in the ratio of 1:10 to the weight of the total casting component. The moment of inertia of the secondary mold is present in the ratio of 2:200 to the moment of inertia of the total casting component.
