  • Publication number: 20220362976
    Abstract: A method produces a substrate shielded from electromagnetic radiation. The method includes i) providing a first polymer material (a) or a precursor thereof containing at least one conductive filler and at least a second polymer material (b) or precursor thereof; ii) obtaining a substrate by subjecting the first polymer material (a) or the precursor thereof and the second polymer material (b) or the precursor thereof to shaping with material bonding of the first polymer material (a) and the second polymer material (b), and polymerizing, if present, the precursors; and iii) at least partially surrounding an electronic component with the substrate obtained in step ii). A polymer component of the first polymer material (a) includes a thermoplastic elastomer or at least one thermoplastic elastomer, selected from the group consisting of, e.g.

  • Patent number: 11497151
    Abstract: A sealing arrangement includes: a first machine element and a second machine element, each made of an electrically-conductive material; and a seal. The first and second machine elements are sealed against one another by the seal. At least one of the machine elements is made of an electrically-conductive plastic which is at least partially covered by an electrically-insulating, injection-molded skin as a result of production. The seal has an electrically-conductive support body. The support body has at least one substantially mandrel-shaped projection comprising an electrically-conductive material which is arranged on a side of the support body facing the injection-molded skin and completely penetrates the injection-molded skin.

  • Patent number: 10746062
    Abstract: It is described a gasket for a valve of an internal combustion engine having a central axis and comprising: an elastically deformable sealing element having an annular shape with respect to the aforesaid axis and adapted to be externally arranged on the valve, and a support element, also having an annular shape with respect to the aforesaid axis, coaxially arranged on at least part of the sealing element so that this latter is radially pressed between the support element and the valve; the support element having, along its side wall, at least one through window to allow the evacuation of the heat generated in use during the operation of the valve.

  • Patent number: 10557389
    Abstract: It is described a gasket for a valve of an internal combustion engine, having an axis and comprising an annular sealing element to be externally arranged on the valve and an annular support element, coaxially arranged on the sealing element to press it radially on the valve; the support element comprising a first annular component, internally cooperating with the sealing element, a second annular component, coaxially surrounding the first component, and snap coupling means between these components; the second component comprising an annular main body and an outer annular end flange; the main body further having an annular edge projecting towards the axis and defining an axial abutment for the first component; the snap coupling means comprising two or more hooking projections angularly equidistant about the axis, cantileverly extending from the annular edge towards the flange and cooperating in contact with the first component to abuttingly keep it against the annular edge.

  • Patent number: 7413696
    Abstract: A method for the production of elastomer and duromer molded items in an injection molding process using an injection molding machine with a respectively separately heatable filling unit, injection unit and cross-linking tool. The filling unit is heated to a temperature which is non-critical with regard to the cross-linking reaction of the plastic to be treated. The injection unit is heated to a temperature which is slightly below the cross-linking temperature of the molding material used.
