The present invention relates to a punching tool of a sintering press, comprising at least one lower punch and an upper punch, a first punch of the upper punch and/or lower punch having a top piece that is asymmetric with respect to an axial axis of the punch press. The first punch has a geometry which widens from the top piece towards a base and is also asymmetric with respect to the axial axis of the punch press. The invention further relates to a method for pressing at least one powdery material to a green body in a sintering press.

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.

A tablet press comprises a gate and a control apparatus configured to generate a switching signal. A drive apparatus is configured to move the gate in response to the switching signal received from the control apparatus between a first switching position and at least a second switching position. At least one sensor is configured to generate a detection signal when the gate reaches one of the switching positions. The control apparatus receives the detection signal and is configured to output a switching signal to the drive apparatus to at least partially move the gate back into a home position when there is a switching signal to move the gate out of the home position and there is no detection signal received from the at least one sensor. The control apparatus subsequently outputs a switching signal to again move the gate out of the home position to a target position.

A modular system for producing dosage-form bulk material in the form of dosage-form base materials or dosage forms. The system includes at least one processing unit (2) which includes a plurality of process stations, at least one container for receiving dosage-form bulk material, and at least one handling system, the at least one handling system transferring the containers between process stations. Also described is a method for producing dosage-form bulk material.

The present disclosure describes a compression device, a compression process, a method of producing synthetic materials and a method of sample characterization. The present disclosure belongs to the fields of Physics, Chemistry and Engineering.

A press base assembly, a strengthening ring for use with press bases and related methods are disclosed. In one embodiment, a press base assembly includes a press base having a body that includes a piston cavity at one end. The body, at a second end opposite that of the piston cavity, may exhibit a desired geometry. A strengthening ring may be shaped, sized and configured to substantially mate with the geometry of the second end of the body and be placed thereover. For example, the geometry of the second end may be substantially circular exhibiting a particular diameter and circumference. The strengthening ring may have substantially circular internal surface sized and configured such that the strengthening ring is positioned on the second end of the body in a manner that results in an interference fit between the two components.

A metal-powder and/or ceramic-powder press device includes at least one first punch (11) which, in a pressing position, is arranged to pass from a first side into a die opening, filled with ceramic and/or metal powder, of a die (13). At least one second punch (12), in the pressing position, is arranged to pass from a second side into the die opening, filled with ceramic and/or metal powder, of the die (13). A position measuring device determines a position of the first punch (11) and includes a first measuring element (16) and a second measuring element (19). The first measuring element (16) is connectable to the first punch (11) and the second measuring element (19) is connectable to the second punch (12), such that a relative position of the measuring elements to one another changes during the pressing operation. A sensor device determines the change in the relative position.

A rotary tablet press machine comprises a rotating compression turret which includes a die table, provided along a circumferential portion thereof with a plurality of dies, a plurality of first punches and second punches associated with respective dies; a dosing station for dosing high-porosity powdered product in the dies; a compression station provided with a first and a second compression roller adapted to linearly move respectively the first punches and the second punches within the respective dies in order to compress said product and producing tablets; and a compacting station arranged between the dosing station and the compression station and provided with at least one compacting cam adapted to push the first punches and/or the second punches within the respective dies in order to compact the dosed product and allow air in said product to exit.

High pressure presses, components for high pressure presses and related methods are provided herein. In one embodiment of the invention, a press base may include a piston cavity formed in the press base and a piston cavity sleeve positioned in the piston cavity. The piston cavity sleeve may include a wall having an outer surface and an inner surface opposite the outer surface. The piston cavity sleeve may further include a floor having an upper surface and a lower surface opposite the upper surface. An outer radius may be formed at a juncture of the outer surface of the wall and lower surface of the floor and an inner radius may be formed at a juncture of the inner surface of the wall and upper surface of the floor. The inner radius may exhibit a radius of curvature that is greater than a radius of curvature of the outer radius.

A rotary tablet press comprises a rotor comprising a rotary drive configured to rotate the rotor and a die plate that rotates with the rotor and comprises a plurality of cavities and a plurality of upper and lower punches. A rotational speed governor is configured to drive the rotary drive of the rotor by comparing a measured rotor rotational speed with a target rotational speed value. A pilot control apparatus is configured to provide an additional target torque for driving the rotary drive. The additional target torque is based on values of a pressing force of at least one of the upper and lower punches input into the pilot control apparatus.
