Abstract (en)
[origin: WO2020169403A1] The invention relates to a method for powder pressing at least two press parts, in particular ceramic powder press parts and/or metal powder press parts, wherein a first powder (17) for pressing a first press part is filled into a first cavity (13) of a matrix (12) with a first filling height and a second powder (18) for pressing a second press part is filled into a second cavity (14) of the matrix (12) with a second filling height, wherein the first and second filling heights are individually adjusted. Preferably, the first powder (17) is filled via a first filling shoe (10) and the second powder (18) is filled via a second filling shoe (11), wherein the two filling shoes (10, 11) are, at least partially, not moved simultaneously. The invention also relates to a powder pressing device which is suitable for carrying out said method.
