Patent number: 10766064Abstract: 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 Al2O3.Type: GrantFiled: June 22, 2012Date of Patent: September 8, 2020Assignee: Oskar Frech GmbH + Co. KGInventors: Norbert Erhard, Helmar Dannenmann, Juergen Kurz, Andreas Sydlo, Daniel Gerner

Patent number: 9233417Abstract: 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.Type: GrantFiled: November 24, 2010Date of Patent: January 12, 2016Assignee: Oskar Frech GmbH + Co. KGInventors: Norbert Erhard, Helmar Dannenmann, Juergen Kurz, Andreas Sydlo, Daniel Gerner

Patent number: 8376025Abstract: 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.Type: GrantFiled: December 19, 2008Date of Patent: February 19, 2013Assignee: Oskar Frech GmbH + Co. KGInventors: Norbert Erhard, Helmar Dannenmann, Juergen Kurz, Knut Morgenstern, Wolgang Nendel, Tino Zucker, Bernd Zimmer, Martin Kausch
