The selected material feed cylinder receives the molding material and discharges the same to the cavity mold supporting structure. Displacement means in the form of a dual piston cylinder having a selectively variable stroke is provided for feeding the molding material through the selected material feed cylinder. The apparatus further provides for control means for controlling the length of travel of the displacement means depending upon the material feed cylinder selected for use in the apparatus.
