Abstract: A metallic cast component includes at least one microstructured functional element on a predefined surface area of the component with a relief-shaped structure sized in a micrometer range in at least one spatial direction for realizing a particular function. The functional element has at least one characteristic dimension of a length of less than 100 ?m.

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.

Abstract: The invention relates to a molding method for 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 fulfil 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. The aim of the invention is to simplify and accelerate a primary shaping method of this type, making it more cost-effective and attractive for mass-production and use on a large scale, thus opening new avenues of application. To achieve this, at least one functional element is formed in a negative impression that is configured on the surface of the mould. The invention also relates to a mould, a core, a core box, a model, an original form and a master pattern for carrying out said primary shaping method.
