Abstract (en)
[origin: WO2020094486A1] The present relates to a method for manufacturing a component (10) having a three-dimensionally structured surface from a semi-finished product (1), to a semi-finished product (1) required therefor, and to a component (10) manufactured in this manner. The method is characterised in that a pattern-like predetermined bending point (4) is produced in the semi-finished product (1), and in that pressure is subsequently applied to the surface of the semi-finished product (1), which pressure is metered such that the pressure causes plastic deformation of the semi-finished product (1) along the predetermined bending point (4) which results in a component (10) having a three-dimensionally structured surface.
