Abstract
A cast component, in particular for a vehicle, has a surface structuring arranged on at least one wall portion of the cast component. The surface structuring forms a surface of the wall portion, and stiffens the wall portion. The surface structuring is formed by a plurality of evenly shaped depressions in the surface of the wall portion, which depressions are mutually spaced apart, leaving interconnected webs, and produce tapered sections on the wall portion.
Claims5
A cast component, comprising:
- at least one wall portion of the cast component;
- a stiffening surface structuring configured as a surface of the wall portion, the stiffening surface structuring stiffening the wall portion, wherein
- the stiffening surface structuring comprises a plurality of evenly shaped depressions in the surface of the wall portion,
- the plurality of evenly shaped depressions are mutually spaced apart to leave interconnected webs and produce tapered sections of the wall portion, and occupy less than an entire surface of the wall portion of the cast component, and
- the plurality of depressions, in a top view on the surface of the wall portion, are configured to be hexagonal and form a honeycomb structure.
