A mold for injection molding processes and a molding process that uses the mold. The mold has, at at least one part of the surface of its cavity raised portions which are longitudinally extended, are arranged side by side and are oriented substantially in the direction of the flow of the melted plastic material that is injected. During the process, the surface of the cavity of the mold is kept at a temperature that is lower than the glass transition temperature, in the case of molding of plastic material constituted by amorphous polymers, and lower than the crystallization temperature, in the case of molding of plastic material constituted by semicrystalline polymers.

Some embodiments of the invention provide methods that can create large area complex patterns for nanoimprint molds without or with very litter of the use of the charged beam or photon beam direct-writing of nanostructures. Some embodiments of the invention use (i) Fourier nanoimprint patterning (FNP), (ii) edge-guided nanopatterning (EGN), and (iii) nanostructure self-perfection, and their combinations.

A tool for producing a fiber composite component includes at least two tool portions which have partial cavities and which are moved together in a production position in such a manner that they form a cavity, in which cavity the fiber composite component is produced. Associated with at least a first tool portion there is a retention element which retains the fiber composite component produced in the first tool portion when the tool portions are moved apart after the production of the fiber composite component.
