Abstract (en)
[origin: US4600374A] 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.
