  • Patent number: 9365001
    Abstract: A thermally conductive sheet has cut surfaces with low surface roughness and hence shows reduced thermal resistance at the interfaces, and high thermal conductivity in the thickness direction. Thus, the thermally conductive sheet can be interposed between any of various heat sources and a radiation member. The process for producing the thermally conductive sheet includes at least: an extrusion molding step in which a thermally conductive composition containing a polymer, an anisotropic thermally conductive filler, and a filler is extruded with an extruder to thereby mold an extrusion-molded product in which the anisotropic thermally conductive filler has been oriented along the extrusion direction; a curing step in which the extrusion-molded product is cured to obtain a cured object; and a slicing step in which the cured object is sliced into a given thickness with an ultrasonic cutter in the direction perpendicular to the extrusion direction.

    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.

  • Publication number: 20100285187
    Abstract: A cutting mechanism (40) in a preferred form of an ultrasonically vibrating titanium knife (42) is moved in a cutting path parallel to but without physical contact with the die face (18) of an extrusion die (16) with its faces (46, 48) at a minor acute angle relative to the die face (18). The die face (18) is at an acute angle to the conveyance direction of a conveyance mechanism (12) defining a preferred form of a takeaway device. The cutting mechanism (40) is moved in a return path from the completion of the cutting path in the extrudate direction away from the die face (18), away from the conveyance mechanism (12), and then towards the die face (18) to the initiation of the cutting path. The cutting mechanism (40) is spaced from and does not physically contact the conveyance mechanism (12) at all times in the cutting path so that the individual piece is cut from the extrudate in mid-air.

  • Publication number: 20100272843
    Abstract: The invention relates to an ultrasonic device for molding micro plastic parts, which combines: a) a mold cavity configured in a mold having an inlet for supplying plastic material to a chamber with an access opening and the chamber facing the cavity at a distal end in relation to its access opening; b) a cantilevered ultrasonic vibration element associated with an ultrasound generator, with an end portion or tip inserted tightly into the chamber through the access opening in an axially centered manner; c) a movement device for generating a relative movement between the end portion and the parts of the mold so that the end portion engages with the supplied plastic material and exerts a pressure of pre-determined magnitude thereon upon activation of the ultrasonic vibration element.

  • Publication number: 20100180407
    Abstract: Apparatus and process are described for forming projections on a substrate for use as hook-type fasteners in touch fastening systems, wherein vibration energy may be used to soften a substrate which may be positioned between a mold and a source of vibration. The mold may include a plurality of cavities into which the softened substrate may be forced to form the projections. The substrate may comprise a film, sheet, web, composite, laminate, etc. and be useful as an attachment strip for temporary or permanent fastening. The source of vibration may be an ultrasonic horn. The process to form such projections may be operated in a continuous, semi-continuous or intermittent manner.

  • Patent number: 7718097
    Abstract: A process for producing a plastic lens comprises, using a mold constituted with a pair of mold members facing each other and a plastic gasket which fixes the mold members to form a cavity and has an inlet for injecting a composition of a material monomer into the cavity, injecting the composition of a material monomer into the cavity through the inlet of the plastic gasket, sealing the inlet of the plastic gasket and, thereafter, conducting polymerization, wherein the inlet of the plastic gasket is sealed by the ultrasonic welding. No striae is formed in the produced lens, and the operations of the production can be performed efficiently at a high speed.

  • Publication number: 20090324765
    Abstract: An apparatus for the forming of a lay-up of fibre composite material, in particular in the aerospace sector is provided. In this case, the apparatus has at least one forming tool, which has a surface contour corresponding to a desired geometry of the lay-up after the forming, and a tool carrier, to which the at least one forming tool is releasably fastened. From a further viewpoint, the invention makes available an apparatus with a modular structure, it then being possible for any desired forming tools to be combined with the tool carrier according to requirements. This leads in particular to less laborious handling, since it obviates the need for handling of the comparatively large tool carrier.
