Patent number: 10994329Abstract: A device (10) for producing die-cast components with a die-casting mold (12) and a discharge device which is provided for controlled evacuation of a mold cavity. The device (10) includes at least one vacuum unit (18) and at least one suction line (20) which connects the die-casting mold (12). The suction line (20) terminates at a mold vacuum valve (21) in the mold cavity. The device (10) is connected to a central control system (1). A filter module (2) is inserted in the at least one suction line (20). The filter module (2) contains at least one filter, a moisture sensor, and a pressure sensor.Type: GrantFiled: October 20, 2017Date of Patent: May 4, 2021Assignee: MAGNA BDW TECHNOLOGIES GMBHInventors: Christian Werner, Armin Dugum

Patent number: 9777360Abstract: A method for heat-treating a cast component composed of an aluminum base alloy, in which method the cast component is annealed at a predetermined annealing temperature for a predetermined annealing period in a first heat transfer medium and then transferred into a water bath. Between being annealed and transferred into the water bath, the cast component is transferred into a second heat transfer medium at a predetermined intermediate cooling temperature, where it is held for a predetermined intermediate cooling period.Type: GrantFiled: July 20, 2011Date of Patent: October 3, 2017Assignee: MAGNA BDW Technologies GmbHInventors: Jürgen Wüst, Dirk E. O. Westerheide

Patent number: 8997834Abstract: A method for the production of a hollow body from die casting aluminum in a die casting machine with a die casting die having mould parts with a stationary mould part and with at least two movable mould parts. The movable mould parts are guided in at least one further movable mould part of the die, so that, in the closed position of the die, the movable mould parts are blocked at least by way of an interlock which is attached to the stationary mould part.Type: GrantFiled: February 4, 2013Date of Patent: April 7, 2015Assignee: MAGNA BDW Technologies GmbHInventors: Christian Herrmann, Holger Angermeier, Georg Willnhammer
-
Patent number: 8978733Abstract: A process for producing a rotationally symmetrical cast aluminum component by die casting, which is reworked partially on its inner and/or outer lateral surfaces. At least a part of the lateral surfaces is not treated and is used as a non-positively locking bearing surface for installation in an assembly and also for bracing the component.Type: GrantFiled: December 22, 2012Date of Patent: March 17, 2015Assignee: MAGNA BDW Technologies GmbHInventors: Rocco Hahn, Christian Herrmann, Korbinian Niedermeier, Richard Weizenbeck
