For filling and emptying the crucible the stopper valve is actuated. Here too must the dosing accuracy with the help of a float be improved.
  • the disadvantage of this system is that lack of process reliability of the plug valve and Fluctuations in temperature and dosing accuracy as a result of metal buildup and leakage and not Finally, a lot of effort and wear on mechanical Components.

Through the associated with a pressure increase and the due to pressure reduction in the pressure chamber occurring increase in the melt game gel can in volume flow entering the pouring tube can be influenced. The result is an optimal filling of the Casting mold and an equally optimal portioning of the Ensure the amount of melt applied in each case.

Through this Possibility to ensure that the Inlet opening of the pouring tube free of molten metal is before the inlet opening is closed. Nice in this way there is a risk of developing a Pressure surge when closing the opening clearly reduced.
