  • Publication number: 20240359398
    Abstract: A method for producing a molded product formed of foamable plastics particles using a foaming tool for processing the foamable plastics particles, wherein the molded product includes at least one region that forms at least one portion of a cavity. The method for forming the molded product includes introducing pre-foamed plastics particles into the cavity, and processing the pre-foamed plastics particles into the molded product by expanding the pre-foamed plastics particles such that the pre-foamed plastics particles expand in the cavity thereby forming the molded product. At least one part of a surface structure of the at least one region forming a surface of the at least one portion of the cavity is produced by an additive method. The surface structure includes multiple elevations and depressions in the surface of the foaming tool.

  • Patent number: 9568393
    Abstract: A device is provided for the early detection of crack formations in work pieces or in components that are subjected to mechanical loading. Wherein in the region of at least one surface at risk of cracking there is arranged at least one testing chamber that is formed by a generative process of manufacturing the work piece or a portion of a work piece and to which a testing medium under pressure is admitted. Either a pressure sensor for determining a drop in pressure resulting from a crack formation of the work piece is connected to the testing chamber or a gas sensor that can also react to a testing medium escaping from the testing chamber in the event of crack formation is arranged in the vicinity of the testing chamber.
