The porosity of the castings mainly depends on the dosed molten metal to the chamber. The switching point between the slow and fast movement of the piston is pre-calculated by the filling volume of the cavity. The inaccuracy of the dosed quantity is not corrected by the casting machine. The switching point of the piston must be adjusted from casting to casting according to the amount of metal added. This research shows the effect of dosed molten metal volume on porosity.
