More Information
Summary:A sintering press includes 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. 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 during insertion and extraction therefrom during a pressing step in the production of the green body.
