1. A process for producing a component comprising at least two segments
connected to one another via one or more connecting elements, the process comprising:
casting a casting in a casting space of a casting mold,
wherein
the casting is processed after casting such that the casting comprises the one or more connecting elements and the at least two segments of the component, and
bending the component at the one or more connecting elements such that the component reaches a maximum length L along an axis A, and this maximum length L is longer than a maximum extent M of the casting space,
wherein the casting space of the casting mold, in three spatial directions, has a maximum height h, a maximum width b, and a maximum depth t, and
wherein the maximum length L of the component is subject to one of the following conditions:
