  • Plastic component having visible part and light source
    Patent number: 7985008
    Abstract: The present invention relates to a plastic component having a visible part that is made in one single layer from a plastic molding compound and that comprises a transparent or translucent matrix, and having a light source that comprises one or more lamp elements, situated under the surface of the visible part. The visible part is implemented as essentially opaque in relation to daylight and transparent or translucent in relation to the light emitted by the lamp elements. The visible part also contains admixed effect pigments and defines a surface appearance image which, when the light source is inactive, essentially corresponds to the surface appearance image of the remaining wall of an object in which the plastic component is installed and which, when the light source is active, is essentially determined by the light source activity.

  • Method for equalizing the orientation of fillers and/or distribution of fillers in injection moulded parts
    Patent number: 7883659
    Abstract: The present invention relates to a method for equalizing the orientation of fillers and/or distribution of fillers in a molding compound comprising filled plastic material of an injection molded part. A method of this type is required in particular during injection molding. The method according to the invention is characterized in that the injection mold and the molding compound are supplied with sound during injection molding in the injection mold. The sound has a frequency in the range of the spectrum of the first ten natural frequencies of the filler-matrix system. By supplying with this sound, the fillers, for example fibers, are distributed within the injection molding compound in a more isotropic manner with respect to their orientation and distribution so that significantly better mechanical and optical properties of the injection molded part are produced.

  • Anionically produced polyamide and method for the production thereof and also a method for reprocessing polyamide
    Patent number: 6809173
    Abstract: The invention relates to a polyamide with low viscosity degradation after remelting which can be produced by anionic polymerization of lactam in the presence of alkaline catalysts and if necessary activators and the method for production of the polyamide. The invention relates furthermore to a method for reprocessing anionically produced polyamide.
