Abstract
A component is made of at least two segments connected to one another in a movable manner via one or more connecting elements. The component is made of a casting or parts of a casting which is cast in the casting space of a casting mold. The component is longer than the maximum extent of that casting space when the component is aligned via the movable connecting element(s), such that it attains its maximum length L along an axis A. A process for producing the component is also provided.
Claims14
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:

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 Lis 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 at least twice as long as either the maximum depth t, the maximum width b, or the maximum height h.
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 component consists of microcellular polyurethane.
