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.

A particle foam component has a foam body, which is provided with a cover layer made of a plastic material at least in partial areas of its outer surface. The foam body has a compressed surface structure in its areas supporting the cover layer. The cover layer is bonded in substance to the compressed surface structure of the foam body. For producing the particle foam component, the foam body is foamed in a mold and the cover layer is foamed or molded integrally in a subsequent method step. A compressed surface structure is formed in the surface areas supporting the cover layer before applying the cover layer, and the cover layer is bonded in substance to the compressed surface structure.

A conveying device for molten metal in an injection die casting unit, has a storage container for the molten metal and a conveying duct delivering the molten metal to a mold cavity. The conveying duct includes a cylinder bore with a piston disposed in an axially adjustable manner. A collection chamber, from which the molten metal is introduced through an onward line into the mold cavity upon axial displacement of the piston, is provided for the molten metal. An annular space, which is connected via at least one filling bore to the collection chamber, is formed between the outer wall of the piston and the inner wall of the cylinder bore. The filling bore, on an end which opens into the collection chamber, is closable by means of a valve body which is connected to an adjustable valve rod which is displaceably disposed in an axial bore of the piston.
