A mold of a casting machine is filled to make a cast article. The method includes providing a molten metal to a casting chamber in fluid communication with the mold, the casting chamber having a supply conduit for introducing a gas into the casting chamber, and the casting chamber having an evacuation conduit for delivering the molten metal from the casting chamber to the mold. The method also includes controlling the filling of the mold during a first time interval by delivering the molten metal from the casting chamber to the mold at a first rate. The method further includes controlling the filling of the mold during a second time interval by delivering the molten metal from the casting chamber to the mold at a second rate. The filling of the mold decelerates from the first rate to the second rate and the second rate does not exceed the first rate.

Method for filling a mold

A method for producing a cast article comprising the steps of: (a)providing a casting apparatus having a mold, a casting chamber containing a molten metal under pressure and a fluid under pressure, the casting apparatus having a first supply port for supplying the molten metal to the casting chamber and a second supply port for supplying the fluid to the casting chamber; (b) supplying the molten metal to the first supply port; (c) supplying the fluid to the second supply port; (d) determining the amount of the molten metal in the casting chamber as a variable V ; (e) determining the amount of the fluid in the casting chamber as a variable V ; (f) determining the amount of humidity in the casting chamber as a variable V ; (g) determining the amount of the fluid entering the casting chamber as a variable V ; (h) determining the pressure of the fluid in the casting chamber as a variable V ; (i) determining the amount of the molten metal needed to produce a cast article in the mold as a variable V ; (j) determining the change in the pressure of the molten metal in the mold as a variable V ; (k) sensing the position of the molten metal with respect to the mold as a variable V ; (l) providing a control panel, wherein the control panel receives a signal representative of the variables V V ; and (m) adjusting the supply of one or both of the molten metal or the fluid in response to at least one of the signal representative of the variables V V
