| 20120273530 | Casting Unit for a Diecasting Machine - 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. | 11-01-2012 |
| 20120145352 | Feed Block Unit, Feed System and Control Device for a Pressure Die-Casting Machine - A feed block unit for a hot-runner feed system of a pressure die-casting machine includes a block body in which is incorporated at least one melt-conveying channel running out of the block body by way of a sprue orifice close to the gate, and a heating system, integrated into the block body, for the at least one melt-conveying channel. The feed block unit is designed as a structural unit which is insertable independently into a respective casting mould, and/or the heating system integrated therein includes at least a first heating device for supply channel heating and a second heating device, which can be controlled independently of the first heating device, for sprue channel heating. With this modular hot-runner feed system, individual temperature profiles can be predetermined and set for the respective feed block unit. | 06-14-2012 |
| 20110000634 | Casting Machine System and Process for Producing Hybrid Metal/Plastic Articles - 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. | 01-06-2011 |
| 20090302192 | Release Agent Spray Device for a Casting Machine - 1. Release agent spray device for a casting machine. | 12-10-2009 |
| 20080289791 | Feed Back Unit, Feed System and Control Device for a Pressure Die-Casting Machine - A feed block unit for a hot-runner feed system of a pressure die-casting machine includes a block body in which is incorporated at least one melt-conveying channel running out of the block body by way of a sprue orifice close to the gate, and a heating system, integrated into the block body, for the at least one melt-conveying channel. The feed block unit is designed as a structural unit which is insertable independently into a respective casting mould, and/or the heating system integrated therein includes at least a first heating device for supply channel heating and a second heating device, which can be controlled independently of the first heating device, for sprue channel heating. With this modular hot-runner feed system, individual temperature profiles can be predetermined and set for the respective feed block unit. A control device authorizes a mould-filling operating to take place dependent on whether temperatures detected in the hot-runner feed system lie within predeterminable setpoint temperature ranges. | 11-27-2008 |
