This application relates to an anti-stiction flexible mold comprising a layer of an anti-stiction silicon dioxide deposited onto a flexible substrate. There is also provided a method for fabricating an anti-stiction flexible mold comprising the steps of a) depositing a layer of silicon dioxide on a flexible substrate; and b) interacting the layer of silicon dioxide with an anti-stiction agent to form the anti-stiction flexible mold. The resulting anti-stiction flexible mold may have superior anti-stick properties and may enable easy separation of mold and substrates after imprinting.

A method for producing insulated winding elements for an electric machine includes steps V1 to V6, as follows: V1providing a line element; V2applying an insulation; V3impregnating the insulation with resin; V4inserting the insulated winding element into a press mold (1) and pressing; V5curing the impregnation; V6removing the winding element from the press mold (1) and cleaning the press mold (1). The base body (10) of the press mold (1) is formed of metal, and the surfaces of the press mold (1) that come into contact with resin during the process have a coating. The coating has two sublayers (11, 12). A first sublayer (11) is in direct contact with the base body (10) and is formed as a priming coat. A second sublayer (12) is in direct contact with the priming coat (11) and is formed as an anti-adhesion layer of fluorinated polyurethane.
