  • Publication number: 20230201913
    Abstract: A method for producing a hollow article made of amorphous metal comprising the steps of: a) providing a metal composition, b) melting the composition according to step a) in order to obtain a melt, c) introducing the melt according to step b) into a cavity of a casting mold, the casting mold comprising an inner core, at least a portion of the lateral surface of the inner core being surrounded by a separation element, d) cooling the melt in the casting mold in order to obtain a molded part made of amorphous metal, e) removing the inner core and the separation element from the molded part according to step d) in order to obtain a hollow article made of amorphous metal. The present invention also relates to a hollow article made of amorphous metal, more particularly to a pipe made of amorphous metal.

  • Patent number: 11318649
    Abstract: One aspect relates to an injection molding system for the injection molding of amorphous metals, an injection molding unit for the injection molding of amorphous metals and an injection molding process for amorphous metals. The injection molding system includes a channel for feeding a molten metal and a slider unit including a slider and a pressure system. The slider is located between the channel and at least one injection molding cavity and is movable between a rest position and an injection position. In the rest position, the slider blocks the access of the molten metal to the injection molding cavity and in the injection position it allows the molten metal to access the injection molding cavity. The pressure system holds the slider in the rest position and allows the slider to move to the injection position when a minimum pressure is exceeded.
