  • Patent number: 9028936
    Abstract: A housing shell for electrical measuring, controlling and communication devices, in particular the lower housing part of a cellphone, has very great flexural and torsional rigidity in spite of an extremely small wall thickness if it is formed as a part created by a forming operation from the planar blank of a thermoplastically impregnated long-fibered multi-layered mat. Fine-membered functional elements of likewise thermoplastic material are then molded onto the housing shell in an injection mold.
