Abstract
A feed device for a metal melt in an injection molding device of, for example, a metal-molding machine has a reservoir for the metal melt and a feed duct, in which the metal melt can be fed to a mold cavity. The feed duct includes a cylinder bore, in which a piston is arranged axially displaceably. A collection chamber for the metal melt, from which the metal melt can be introduced into the mold cavity through a continuing line as a consequence of an axial displacement of the piston, is provided in the cylinder bore. The cylinder bore is surrounded by a first heater, which has at least one heating element.
