A method of embedding opto-electronic components in a layer, wherein the components are disposed beside one another to be spaced apart on a carrier, including providing a molding tool having a bearing plate, wherein the bearing plate on a lower side includes resilient bearing regions, bringing the bearing plate by way of the resilient bearing regions to bear on upper sides of the components, filling an intermediate space between the components, the carrier, and the bearing plate with a molding material, curing the molding material to form the layer, and removing the molding tool from the layer and the embedded components.

The present disclosure is directed methods for modifying molds of rotor blades of a wind turbine. In certain embodiments, the blade mold is constructed, at least in part, of a thermoplastic material optionally reinforced with a fiber material. In one embodiment, the method includes identifying at least one blade mold addition for the mold of the rotor blade and positioning the blade mold addition at a predetermined location of the mold of the rotor blade. Further, the blade mold addition is constructed, at least in part, of a thermoplastic material. Thus, the method includes applying at least one of heat, pressure, or one or more chemicals at an interface of the blade mold addition and the mold so as to join the blade mold addition to the mold. In further embodiments, the methods described herein are also directed repairing thermoplastic blade molds.

A method of masking a mould for moulding a wind turbine blade shell part, the method comprising the steps of: arranging a masking device in a mould so that the masking device covers the non-coating zone of the mould surface, spraying a coating onto a mould surface of the mould so that the coating is applied to a coating zone of the mould surface and prevented from being applied to a non-coating zone of the mould surface by the arrangement of the masking device, and removing the masking device from the mould so that the non-coating zone is exposed. The masking device is configured so that, upon terminating spraying of the coating at the first longitudinal boundary of the coating zone, a lip portion of the masking device is separated from the coating applied on the coating zone by a gap.

A method for manufacturing a master mold for imprinting, with which structures formed in a desired forward taper can be formed on a base material. This method comprises a coating step in which a resist having a predetermined film thickness is coated on a base material, an exposure step in which the resist coated on the base material is exposed through a mas, and a development step in which the exposed resist is developed, the exposure step involving setting the exposure amount to be equal to or less than twice the minimum exposure amount (Df) at which the resist coated on the base material undergoes solarization across the entire thickness of the resist, and exposing predetermined portions of the resist, so that the side surface shape of the structure constituted of the resist formed by development in the development step is a forward taper.
