A casting unit for a die casting machine has a casting container with a casting chamber, a casting piston, which is arranged in an axially movable manner in the casting chamber, a melt bath connection opening, a melt inlet channel from the melt bath connection opening to the casting chamber, a melt outlet channel, which leads out of the casting chamber separately from the melt inlet channel, and a shut-off control valve for the melt inlet channel. The shut-off control valve has a valve main body arranged on the casting container, a valve seat and a valve closing body. The valve main body is held on the casting container at a lateral valve assembly region of the casting container in a manner accessible from the outside and includes the melt bath connection opening, and/or the casting piston is of a spool type, and the shut-off control valve is located with its valve closing body in the melt inlet channel at a flow-technical distance from the melt bath connection opening on the one hand and from the casting chamber on the other hand.

A casting component and method for the application of an anticorrosive layer to a substrate, such as the casting component, are provided. The casting component for a device for casting a metal melt includes a metallic basic body and a melt contact surface region which is exposed to the metal melt during casting operation. In the casting component, the metallic basic body is provided in the melt contact surface region with an anticorrosive layer which is resistant to the metal melt and which is formed, using microparticles and/or nanoparticles of one or more substances from a substance group which includes borides, nitrides and carbides of the transition metals and their alloys and also of boron and silicon and AlO.

A diecasting machine casting unit includes a casting chamber body having a casting chamber with a casting material inlet and outlet. A casting piston is movable forward in a longitudinal direction in the casting chamber to discharge casting material from the casting chamber under pressure via the outlet, and is movable back, whereby casting material is feedable into the casting chamber via the inlet. The casting piston extends through a through-passage of the casting chamber body from outside into the casting chamber. An area of free space of the casting chamber is formed between an outer lateral surface of the casting piston and an inner wall surface of the casting chamber body transversely relative to the casting piston longitudinal direction by an outer cross section of the casting piston being appropriately smaller than an inner cross section of the casting chamber body.

A casting machine system includes a first casting machine and a separate second casting machine, wherein the first casting machine is a metal-casting machine and the second casting machine is a plastic-casting machine, or the first casting machine is a plastic-casting machine and the second casting machine is a metal-casting machine. An associated process produces hybrid metal/plastic articles. The casting machine includes a transfer device for transferring a precursor product, produced by a first casting process in the first casting machine, to the second casting machine, in which a hybrid metal/plastic component is formed from the precursor product by a second casting process, and a temperature-regulating device for regulating the temperature of the precursor product in a controllable manner after its removal from the first casting machine, and before starting the second casting process.
