  • Method and press for producing a green compact composite with a predetermined breaking point
    Patent number: 10632538
    Abstract: The invention relates to a method for producing a green compact composite comprising at least a first partial green compact and a second partial green compact, wherein, within one pressing cycle, a powder is introduced into a filling chamber and then separated into a first partial quantity and into a second partial quantity, and, within the same pressing cycle, the respective partial quantities are pressed to form a first partial green compact and a second partial green compact and the partial green compacts are amalgamated after the pressing, wherein the amalgamation forms a press fit between the first partial green compact and the second partial green compact and produces a predetermined breaking point in the green compact composite. Furthermore, the invention proposes a green compact composite, a sintered component and also a press, each of which can be based on the proposed method.
