  • Patent number: 6997231
    Abstract: The invention relates to a method for vacuum diecasting and a diecasting mould (1), especially for diecasting components made of metal or the alloys thereof. The aim of the invention is to provide a better casting quality while simplifying the procedure of the method. To this end, the evacuation of the die cavity (5) and the filling with molten bath are carried out independently from one another.

  • Patent number: 4708620
    Abstract: In a die-casting or injection molding machine transducers are provided for generating a signal corresponding to the injection pressure as well as a signal in accordance with the velocity of the ram device, i.e. the injection screw or the injection piston of the machine. The output signals of these transducers are supplied to a calculating stage for calculating the actual injection power. The resulting signal at the output of the calculating stage is fed to an evaluation device, preferably comprising an indicating device, but also a control circuit, if desired.
