Abstract
A method is disclosed for molding a component with at least one microstructured functional element, which is configured intentionally with a defined structure, in relief, at a defined point on the surface of the component in order to specifically fulfill a function. The element has a characteristic dimension in the micrometer range in at least one spatial direction. The component is shaped from a substantially metallic material using a mould. At least one functional element is formed in a negative impression that is configured on the surface of the mould.
Claims20
A molding method for producing a component with at least one microstructured functional element, comprising the steps of:
- producing a microstructure at a predefined area on a cavity-confronting surface of a molding tool;
- introducing a substantially metallic material in the cavity of the molding tool;
- and
- molding a component in the cavity of the molding tool, thereby reproducing on an outside surface of the component a positive of the microstructure to form a microstructured functional element so as to provide the component at a defined area with a relief-shaped structure sized in a micrometer range in at least one spatial direction for realizing a particular function,
- wherein the functional element has at least one characteristic dimension with the characteristic dimension being a length of less than 100 μm.
