Method for the manufacturing of a matrix and a matrix manufactured according to the method

A method for the manufacture of a matrix having at least one surface section or layer displaying a negative microstructure, the matrix being suitable for inclusion as a mould insert in a mould cavity or in a cavity in a unit for producing plastic components, in order to assign at least one part or surface of said plastic components an opposing or positive microstructure in a corresponding surface section, whereby said layer is exposing the conditions of hardness and wear resistance, the method comprising forming said matrix by providing an original having a surface section displaying a positive microstructure;

• applying onto said original successive layers of different materials or mixtures of materials for building up and producing said matrix, and thereafter either removing said matrix from said original or removing the material building up said original to manufacture a microstructure related surface section of the matrix, that has a sharp negative microstructure;
• a. wherein said surface section related to the original is caused to display said positive microstructure,
• b. wherein said first matrix related layer is a material having an ability to release the matrix surface from the produced plastic components after moulding, curing or polynerization,
• c. wherein said selected material, according to “b”, also retains the pattern on the negative microstructured surface section related to said first layer,
• d. wherein said material in said first layer is a crystalline diamond, a DLC, a nitride, or a carbide,
• e. wherein said first layer is applied onto said original in a thickness of 0,1-100 μm;
• and
• f. wherein a second material layer, having an adhesive capability to the first material layer, is applied onto said first material layer.
