  • Patent number: 7419628
    Abstract: A method and apparatus for manufacturing fiber-reinforced products with integrated insert parts by moulding a heat-bonding resin having a viscosity of about 1-10_6 and about 30-10+6 mPas, between two joinable halves of a separable mould having an upper and lower mould parts forming a cavity therebetween, the inner moulding faces are attached to displaceable fixed parts of a pressing table. Prior to moulding, an insert part is fixed in position in the cavity, and the mould parts each have a set of a support devices displaceable in the cavity relative to the respective moulding faces. According to the method, the resin is located in the cavity before the mold is closes and the insert is in position prior to and during an initial phase of moulding. The support device is removed prior to the setting of the resin in the mould leaving holes in the material, and thereafter the mold parts are held together for filling the holes.

  • Publication number: 20050161862
    Abstract: The invention relates to a method and a moulding tool for manufacturing products of fibre-reinforced thermosetting plastic with integrated insert parts by moulding a material of a heat-bonding resin between two joinable halves of a separable mould that preferably constitutes an upper mould half (6) and a lower mould half (7) that having inner mould faces (10, 11) are attached to a displaceable (8) respective fixed (9) part of a pressing table, whereby prior to the moulding of the product, at least one insert part (4) is fixed in position in the cavity that is demarcated between the moulding faces (10, 11) of the mould halves.
