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.

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.

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.

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.
