  • Patent number: 12121959
    Abstract: A three-plate die casting mold for producing a metal die-cast part by die casting a molten metal includes a first, second, and third mold part, where the third mold part is disposed between the first and second mold parts. Molten metal is feedable to a die cavity through a sprue system where the sprue system has a plurality of feed channels that are disposed in the third mold part and open into the die cavity. The plurality of feed channels have a respective tapering at a die cavity-side end where the respective tapering locally decreases a channel cross section such that a predetermined breaking point is generated during a die casting operation which allows a defined separation of the metal die-cast part from a sprue created in the sprue system when the three-plate die casting mold is being opened.

  • Patent number: 12110063
    Abstract: A hybrid component has at least two component portions, which are connected via at least one connection portion. The at least one connection portion extends in a joining direction. A first component portion is formed from a first material which has a first modulus of elasticity, and a second component portion is formed from a second material which has a second modulus of elasticity different from the first modulus of elasticity. The at least one connection portion is designed at least to compensate for a sudden change in rigidity between the two component portions. The at least one connection portion has a rigidity that increases in the joining direction and in the direction of the component portion with the higher modulus of elasticity.

  • Patent number: 11911843
    Abstract: A method for integrally bonding a cast aluminum component to a joining partner. The method includes laser-treating a region of the cast aluminum component that is to be connected to the joining partner. The laser treatment is carried out via a pulsed laser system having a pulse duration of 100 to 200 ns, and an impulse frequency of 10 to 80 kHz. The method also includes integrally bonding the cast aluminum component and the joining partner.

  • Patent number: 10077082
    Abstract: An aluminum diecast part is provided, in particular in the form of a load-bearing motor vehicle part. In order to protect against sudden breaking loads, at least one tension element, made of a material that can be deformed in a ductile manner and having a different thermal expansion coefficient to the die-cast part, is bonded, in a load-resistant manner to the side of the die-cast part that is external to the load. The die-cast part remains highly deformable, even under the effects of greater temperature fluctuations, by way of the punctiform, shear-resistant interconnection of the die-cast part and the tension element at multiple sites distributed over the bond.
