The invention relates to a method for producing drive belts from different materials by means of casting processes. To this end, a mould core and an outer mould of a casting tool are provided. The circumferential surface of the mould core or the inner circumferential surface of the outer mould is provided with a geometry to be represented on the drive belt. A textile layer is laid on the geometry. The mould core is set into the outer mould so that the mould core and the outer mould define a cavity between them. Optionally, a tension member can be arranged in the cavity and the cavity can be sealed with respect to the environment at least in the region of the geometry to be represented on the drive belt. The textile layer is applied to the surfaces defining the geometry and an elastomer base material is introduced into the cavity.

Methods for manufacturing three-dimensional devices and devices created thereby

In certain exemplary embodiments of the present invention, three-dimensional micro-mechanical devices and/or micro-structures can be made using a production casting process. As part of this process, an intermediate mold can be made from or derived from a precision stack lamination and used to fabricate the devices and/or structures. Further, the micro-devices and/or micro-structures can be fabricated on planar or nonplanar surfaces through use of a series of production casting processes and intermediate molds. The use of precision stack lamination can allow the fabrication of high aspect ratio structures. Moreover, via certain molding and/or casting materials, molds having cavities with protruding undercuts also can be fabricated.
