  • Publication number: 20180257137
    Abstract: The invention relates to a sintering press which comprises at least one upper punch and a lower punch, a powder reservoir for filling a female die of the sintering press with at least one powder material that can be sintered, and a female die for producing a green body using the powder material from the powder reservoir. A first punch of the upper punches and/or lower punches has a punch top which is off-center and asymmetric with respect to an axial axis of the sintering press and which can be moved in the female die along a female die outer wall and/or along an adjacent punch without being guided inside the female die. The first punch is asymmetric in shape between the punch top and the base, which shape at least reduces an axial tilting of the punch and a lateral drag of the punch top on an adjacent outer surface in the female die, in particular prevents such tilting and dragging, during insertion and extraction therefrom during a pressing step in the production of the green body.

  • Publication number: 20170113276
    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.

  • Publication number: 20130264023
    Abstract: A latent heat storage device is formed with a carrier substrate formed of expanded graphite material. Phase change material is infiltrated in the graphite material. A thin graphite sheet provides for the functional heat conductivity into and out of the carrier substrate. After the phase change material (PCM) is infiltrated in the carrier substrate, a density of the infiltrated carrier substrate exceeds its starting density by a ratio of at least 3:1 or 4:1 or more. The volume dimensions of the infiltrated the carrier substrate remain substantially unchanged. In the alternative, the latent heat storage device may also have a PCM coating layer on a thin carrier substrate, wherein the phase change material is interspersed in a carrier matrix forming the PCM coating layer. The composite device may be very thin.
