Embodiments of the present disclosure relate to a hot press and methods of using the hot press. In an embodiment, the hot press can include a pressing element including a flared body. In another embodiment, the hot press can include a compression surface. The compression surface can include a first layer including a monocrystalline material and a second layer including a polycrystalline material, wherein the monocrystalline material and the polycrystalline material include a same primary compound. In a further embodiment, a sample including more than one layer of ceramic oxide material can be hot pressed without a die.

The present invention relates to a device (1) for sintering by pulsating current, the device (1) comprising: —a sintering cell (4) comprising two walls (14a, 14b) facing each other and defining between them a cavity (C) for receiving material to be sintered, —a press (2) arranged for moving one of the walls (14a, 14b) towards the other wall, so as to compress the material, when the material is received in the cavity (C), —means (10a, 10b) of rotating one of the walls (14a, 14b) relative to the other wall, so as to apply a torsional force to the material, when the material is compressed in the cavity (C).

A forming die assembly includes an upper die including a first backup member and a first press member that is attached to the first backup member, has an L shape in a vertical sectional view, and is heat-resistant; and a lower die including a second backup member and a second press member that is attached to the second backup member, has an L shape in the vertical sectional view, and is heat-resistant. The first press member and the second press member press upper and lower surfaces of a workpiece accommodated in a press space that is formed between the first press member and the second press member, so as to produce a forged product.

Apparatuses for forming blocks of compactable material such as snow, having a hollow upper body with a compression chamber within for containing and subsequently compressing the compactable material to form a block that can be used in connection with recreational activities. A lower body having a flat compression plate attached to a top end, is configured to slide within the compression chamber, the compression plate being capable of pushing the compactable material into a hinged lid that is attached to a top end of the upper body and acts to cover a top opening of the upper body. Ferromagnetic materials attached to the underside of the compression plate are configured to contact other ferromagnetic materials attached to the interior walls of the compression chamber, which at least temporarily arrests sliding movement of the upper and lower bodies, and allows a user to fill the apparatus with compactable material.

Provided is a method for producing a compressed body of a powder capable of improving a hardness while suppressing a decrease in production efficiency of the compressed body of the powder. A compressed body 14 of a powder is compression molded by compressing a powder supplied into die holes 18 by a lower punch 31 and an upper punch 32. In the compression molding, a first compression and a second compression following the first compression are performed. In the first compression, the compression is performed at a first compression speed, and in the second compression, the compression is performed at a second compression speed that is lower than the first compression speed.

The present disclosure generally relates to powder packing for additive manufacturing (AM) methods and systems. Conventional powder packing methods are manual and non-standardized, and they result in operator fatigue and potentially product inconsistencies. Powder packing according to the present disclosure improves standardization and reduces turnaround time, with the potential to lower the cost of AM.

In a method for measuring or calibrating utensils, in particular in pressing processes, different dimensions and/or positions of the utensils, such as tools, stamps (16, 17), die units (22), chucks (14, 15, 21) or the like, are determined. A measuring device (10) is provided, with which the utensils are placed relative to one another in the press as in the installed state and are displaceable relative to one another at least in the axial direction (A) of the opening in the die unit (22) forming the die and are measured and/or calibrated individually and relative to one another. The pressed parts and workpieces to be produced using a press can thus be manufactured in a highly precise manner, moreover in high numbers using the same utensils.
