A feed device for an injection chamber of a pressure die-casting or injection machine or for a press tool or a forging press die transfers a billet into an injection chamber or die press. The billet may be of metal or plastic, filled or unfilled, and in a liquid, solid, semi-liquid or semi-solid state. A support with a horizontal axis receives and houses the billet. A ram moves the support and thus transfers the billet into at least one heating system. The ram that transfers the billet also moves the support in a horizontal translational motion transporting the billet from the heating position to a position lying vertically above the injection chamber of the tool or the press die, and then moves the support with a rotational motion about its axis so as to cause the billet to drop, horizontally, due to gravity, from the support into the injection chamber or into the press die.

Equipment (3) for centrifugal casting from a crucible (5) into a mold (8) is modified by the addition of agitation means (19) movable relative to the crucible (5) and a heating furnace (30) which is movable relative to the mold (8) in order to heat the latter, before casting, to a temperature close to that of the alloy in the thixotropic state.
