ABSTRACT:
An apparatus for controlling a molding of a solid product in a mold cavity from molten material which solidifies in the mold cavity, in which first and second conduits are coupled to the mold cavity at spaced positions for carrying the molten material, includes first and second elements, and a controller for controlling the driving the first and second elements repeatedly during solidification of the molten material in the mold cavity so that the molten material is repeatedly moved through the mold cavity. The first element is disposed in the first conduit and the second element is disposed in the second conduit. The first element is adapted to be driven in a forward direction to displace the molten material from the first conduit into the mold cavity and then into the second conduit, while the second element is adapted to be driven in a reverse direction to permit the flow of molten material out of the mold cavity and into the second conduit simultaneously with the driving the first element in the forward direction. The first and second elements are also adapted to be driven in the reverse and forward directions, respectively.
