Abstract: A plate heat exchanger has two metal plates brought into abutment, with a solder material between the plates. The plates are heated up to a first temperature. The plates are placed into a mold, the mold surfaces of which have cavities for envisaged channel structures. Channel structures are formed by local internal pressure forming of at least one plate under pressurization by the tool. The plates are heated up to a second temperature. The plates are solder bonded at the abuted surfaces. A plate heat exchanger has two metal plates, wherein channel structures have been formed in at least one plate and the plates are bonded to one another by soldering away from the channel structures. Eutectic microstructures having a longest extent of less than 50 micrometers are formed in the solder layer.

Abstract: The disclosure relates to a process for producing a formed lightweight metal component from a 6000 series or 7000 series aluminum alloy, having the process steps of heating a sheet metal blank, then homogenizing a solution annealing temperature, quenching the heated blank, and forming the heated blank into a component.

Abstract: A two-blow heating and forming tool for the simultaneous production of two hot-formed and press-hardened motor vehicle components is provided. The tool includes a heating device and a forming device, with at least two contact heating tools and at least two hot-forming and press-hardening tools being arranged next to one another in parallel in a press such that, during a closing movement, two blanks are heated and two heated blanks are hot-formed and press-hardened to form two motor vehicle components. A method for producing hot-formed and press-hardened motor vehicle components using a two-blow heating and forming tool is also provided, the method including producing two mirror-inverted motor vehicle components simultaneously in one press cycle.

Abstract: In a heating device for conductive heating of a sheet metal blank with varying cross sectional surface, the sheet metal blank constitutes a direct component of an electric circuit, wherein an electrically conductive compensation element is provided which is placed onto a surface of the sheet metal blank, wherein a sum of the cross sectional surface of the sheet metal blank and the cross sectional surface of the compensation element results in a current conducting cross sectional surface.

Abstract: In a method, a blank of unhardened steel sheet is subjected in a press tool to a hot forming and press-hardening process to produce a structural part. After press-hardening, at least one linear zone of the structural part is heat treated in order to increase ductility and reduce strength in the linear zone in relation to adjacent regions of the structural part. After heat treatment, a bending or cutting operation is carried out on the structural part along the linear zone.

Abstract: A region of a structural part, which is made of a precipitation-hardened aluminum alloy, is inductively heated to a temperature between 100° C. and 300° C. for a maximum time period of one minute. After undergoing the heating process, the region of the structural part is mechanically shaped by a forming tool.
