  • Publication number: 20260284929
    Abstract: A press moulding method produces a shaped press moulded fiber product, at high pressure and high temperature, by means of a press pad device and a stamp device. The press pad device includes an open space having a bottom part and a wall part and the stamp device has a mating form that provides a product gap in relation to the press pad device, where the fiber product is produced from a sheet like blank having an integrated fibre network that is cut out from a sheet of raw material with an integrated fibre network and formed in the gap. The blank after press moulding will be shaped into the fiber product by providing the blank with at least one excess portion and that the at least one excess portion before pressing or in connection with pressing is pushed into a neighboring portion of the blank to be integrated in at least one reinforcing portion of the fiber product.

  • Publication number: 20240408789
    Abstract: A fiber capsule and a method of compression molding a fiber-based packaging capsule, includes the steps: a raw capsule of a loosely bonded fiber mat is formed, which capsule has an opening; the raw capsule of the loosely bonded fiber mat is positioned on the inside of a substantially rigid mold having inner surfaces defining the molded outer surfaces of the fiber-based packaging capsule; the loosely bonded fiber mat is compression molded by the insertion of a pressurizable compression member through the opening. The pressing device is pressurized at a temperature of 150-250 degrees C.°. The compression molding takes place by reshaping the reshaping pressing device and pressing the inside of the capsule against the inner surfaces of the rigid mold so that a cohesive fiber-based packaging capsule is obtained.
