By melting a shaping material in which a metal powder and a binder are mixed and by carrying out injection molding (primary shaping) in an injection mold, an injection molded body, or an intermediate shaped body are produced. The injection molded body or the intermediate shaped body is placed by a transfer mold and is subjected to a gravity shaping (secondary shaping) with a transformation. A sintered body is manufactured by carrying out debindering and sintering to the injection molded body.

A powder molding press method of a green compact for a cutting insert including: filling a molding space with raw material powder in a state where a lower punch is inserted from below into a hole portion of a die; performing preliminary molding by inserting an upper punch for preliminary molding including a preliminary molding surface having a shape different from a shape obtained by inverting the upper surface of the green compact for a cutting insert in a plane symmetry into the molding space from above such that a thick portion between the upper and lower surfaces in the direction of the insert center line is filled with more raw material powder than a thin portion therebetween, relative to a state before the step of performing the preliminary molding; and inserting an upper punch for final molding into the molding space from above to powder-molding-press the raw material powder.

Provided are a solid oxide fuel cell/electrolytic cell and electric stack, which relate to the field of cells. A metal support frame is molded in one step or more steps through the additive manufacturing technology. And then a fuel/electrolytic cell functional layer is formed on the metal support frame by means of thermal spraying, tape casting, screen printing or chemical vapor deposition method, and self-sealing of the solid oxide fuel cell/electrolytic cell is realized through a dense structure of electrolyte.

A machining segment for a machining tool which is rotatable in a direction of rotation about an axis of rotation includes an underside where the machining segment is connectable to a basic body of the machining tool by the underside. A machining zone has a matrix material and a plurality of first hard material particles where the plurality of first hard material particles are disposed in the matrix material in accordance with a defined particle pattern. Each of the plurality of first hard material particles has a respective projection in relation to the matrix material on an upper side of the machining segment. The projection of at least one of the plurality of first hard material particles is greater than 400 μm.

A method for producing a machining segment for a machining tool, where the machining segment is connectable to a basic body of the machining tool by an underside of the machining segment, includes producing a green body by placing first hard material particles in depressions of a first press punch and applying a first matrix material to the first hard material particles. The green body is processed by hot pressing under temperature and pressure between the first press punch, which forms an upper side of the machining segment, and a second press punch, which forms the underside, to form the machining segment, where the upper side is opposite from the underside.
