The invention relates to a die for arrangement in a press, wherein the die extends along an axial direction between two end faces and forms an inner peripheral surface between the end faces, wherein the die extends from the inner peripheral surface along a radial direction toward an outer peripheral surface and toward at least one centering surface that is disposed in the radial direction on a first diameter, wherein the die has a pressing zone that is spaced apart from the end faces and, in the vicinity of the pressing zone, the die has a greater maximum first stiffness, at least relative to zones of the die that are arranged on the end faces, compared to a pressing force acting on the inner peripheral surface in a direction of a normal vector, and wherein the maximum first stiffness is at least 10% greater than a minimum second stiffness that is present in at least one zone that is arranged on one of the end faces.

The present invention relates to an apparatus, preferably a press, comprising a cavity which is to be filled and at least a first material feed, for a first material, and a second material feed, for a second material, wherein the first and the second material feeds are arranged separately from one another, having a feeding apparatus for feeding the first and the second materials into the cavity which is to be filled, wherein the feeding apparatus has a mouth-opening cross section with at least a first region of the mouth-opening cross section for the first material, and with a second, separate region of the mouth-opening cross section for the second material, for filling the cavity preferably in parallel, and at separate locations. A method and also a blank are proposed in addition.

The present invention relates to a gear wheel containing at least one sintered material having a porosity, the gear wheel having, in addition to the porosity, another noise-reducing means.

Quiet gear wheel and method for producing such a gear wheel

A sintering furnace with a first zone, in particular a burn-off zone, and a second zone, in particular a sintering zone, and also a transitional zone arranged between the first zone and the second zone. The sintering furnace has at least one transporting mechanism for transporting bodies to be sintered on a transporting area. With this transporting mechanism, the bodies to be sintered can be transported from the first zone and through the transitional zone to the second zone. The sintering furnace also has at least one gas removal device with at least one gas removal device opening. Here, the gas removal device opening is at least partially arranged in the region of the transitional zone. Furthermore, a method by means of which gases can be removed from a sintering furnace is claimed.
