  • Method and apparatus for the control of a die casting or similar machine
    Patent number: 6357334
    Abstract: An improved control system for die casting or similar machines wherein a closed loop velocity feedback circuit is supplemented with an integration circuit and two filtering circuits to compensate for the frequency response of the pilot valve in the die casting machine. The integration circuit serves to more accurately cause the velocity of an element being controlled to match the desired/commanded velocity, and also caused the velocity to more rapidly match the desired/commanded velocity.
