  • Patent number: 8499429
    Abstract: In a method for applying a surface structure to a solid body, a structured surface is placed directly or indirectly onto the surface of the solid body and the structure of this structured surface is reproduced in the surface of the solid body, in that an explosive structured layer is arranged on the surface of the solid body and the structure of the explosive structured layer is explosively disseminated into the surface of the solid body. According to the invention, the surface of the solid body is provided with a surface pre-structure before the actual dissemination, at least in regions, wherein the structure of the explosive structured layer is disseminated on at least one partial region of the surface pre-structure so that the surface structure produced results from overlapping of the surface pre-structure with the explosively disseminated structure.

  • Patent number: 6358459
    Abstract: A method for the production of molded bodies comprising foam particles is proposed in which the foam particles are shaped and welded together using microwave energy. The foam particles are accommodated in a foil-like bag and the bag is manually shaped or shaped through the use of a shaped mold with simultaneous change of the shape of the foam particles, and evacuated into a dense package. Microwave energy is subsequently used to melt together at least the surfaces of the foam particles. The method in accordance with the invention is particularly well suited as an economical manufacturing technique for packaging, in particular specialized packaging for models, small production runs, prototypes and the like.

  • Patent number: 6165300
    Abstract: In order to manufacture compound composite bodies having at least two lay with a support material made completely or substantially from a polymer and with a porous layer firmly connected thereto, a substantially microwave-permeable polymer is utilized for the support material and a polymer having microwave absorbing properties is utilized for the porous layer. The polymer for the porous layer, treated with foaming agent, is heated with microwave energy up to the decomposition temperature of the foaming agent. The resulting polymer foam is sufficiently heated using microwave energy that the support material, at its bordering layer adjacent the foamed polymer, is sufficiently melted substantially due to heat conduction out of the foamed layer that, subsequent to cooling, a firm composite between the support material and the foamed polymer is effected.

  • Patent number: 6044677
    Abstract: The present invention relates to a method for surface structuring of workpieces, in particular molds for plastics processing, erosion electrodes or the like, in which a structured surface is applied to an unstructured workpiece surface in order to map the structure into the workpiece surface. In order to provide a method which can be carried out more quickly, and which involves no environmentally hazardous process steps, it is proposed that a structure layer which has the structured surface is arranged between an explosive layer and the workpiece surface, and the structure is forced into the workpiece surface by detonating the explosive layer or a surface-structured explosive layer is arranged on a workpiece surface, and the structure is embossed onto the workpiece by detonating the explosive layer.
