Abstract
A casting device includes a wall which is formed in the manner of a sandwich structure from a front layer, a yielding intermediate layer and a supporting outer layer. In this way, the contraction-related internal stresses which occur during cooling are kept at a low level by the resilient properties of the intermediate layer. As such, the formation of cracks in the component to be cast can be avoided.
