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 method of manufacturing a component includes making a preform from a powdered material, the preform having a density in a range from 70 to 95% of theoretical density of the material, The method also includes sintering the preform using a Field Assisted Sintering Technique (FAST) process to produce a component having a density of greater than 97% of the theoretical density of the material. Components, in particular low aspect components, formed by said method are also described.

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.

A tooling assembly is for a powder compacting press machine, which has a lower punch chuck and a core rod chuck. The tooling assembly has: a lower punch with a lower punch drawbar for holding the lower punch in the lower punch chuck in the powder compacting press machine; a core rod with a core rod drawbar for holding the core rod in the core rod chuck in the powder compacting press machine; and a coupling mechanism configured to enable a connection between the lower punch and the core rod. The coupling mechanism has a male coupling element on an outer surface of the core rod and a female coupling element on an inner surface of the lower punch drawbar. The male coupling element is an elastic element.

A plane plate for a pressing tool of a press in which the plane plate activate a punch of the press by way of at least one lifting cylinder that can be displaced along an axial direction. The plane plate has an upper side that points in a first axial direction and a lower side that points in a second axial direction counter to the first axial direction, a link to the at least one lifting cylinder, a centrally disposed receptacle for contacting the punch or a punch holder of the press, as well as at least a first at least partially cylindrical guiding face which for contacting a first guide column is parallel with the axial direction, and a second at least partially cylindrical guiding face which for contacting a second guide column is parallel with the axial direction; wherein on the lower side of the plane plate the first guiding face has a first lower end and the second guiding face has a second lower end, wherein the first lower end and the second lower end in relation to the axial direction are disposed at mutually dissimilar heights and thus are disposed so as to be mutually spaced apart in the axial direction.

Compaction systems and methods of compacting components are provided. In one aspect, a laminate of a component can be laid up on a tool of a compaction system. The laminate defines a cavity. A noodle is positioned relative to or in the cavity. A noodle ring is then positioned relative to the noodle. For instance, the noodle ring can be placed over the noodle. A cross section of the noodle ring can be shaped complementary to a cross section of the noodle. A plunger of the compaction system is moved so that it engages the noodle ring. Particularly, the plunger is moved in such a way that a force is applied on the noodle ring so that the noodle ring compacts the noodle into the cavity.

A plane plate for a pressing tool of a press in which the plane plate for activating a punch of the press by way of at least one lifting cylinder is displaceable along an axial direction. The plane plate has a link to the at least one lifting cylinder, a centrally disposed receptacle 9 for contacting the punch or a punch holder of the press and at least one at least partially cylindrical guiding face, which for contacting a first guide column is parallel with the axial direction. The plane plate has, in at least a first cross section which runs through the link and the receptacle parallel with the axial direction and along a radial direction that runs so as to be perpendicular to the axial direction, at least a first region between the link and the receptacle, having a wall thickness, wherein the wall thickness in the first region and so as to be spaced apart from the receptacle as well as from the link has at least a minimum.

A plastic material crushing and compacting structure, including: a barrel, a upper side thereof configured with an input hole, and an inside thereof a driving device, an inside of the driving device a wireless transceiver module; a pair of clamping seats, configured below the input hole, and used to clamp an input plastic material item (e.g. plastic bottle, paute, etc.) to prevent the plastic material item from ejecting; a crushing device, configured below the pair of clamping seats and used to crush the input plastic material item, and provided with crushing device driver; and a telescopic push rod, configured below the driving device and moved vertically, a bottom of the telescopic push rod provided with a compressing face, several strip supports configured on the compressing face, and a gap arranged between each two adjacent strip supports, each of the gaps is the same size or not the same size.

A method for forming a product of compressible material includes preparing compressible material, assembling a molding fixture, filling the compressible material into a filling tube of the molding fixture, clamping the filling tube by a clamping mechanism of the molding fixture, moving an adjusting screw of the molding fixture downward in the filling tube to compress the compressible material, delivering the molding fixture to a heating module to perform a heating process so that the compressible material s heated and melted, delivering the molding fixture to a cooling module to perform a cooling process so that the compressible material is cooled and solidified to form a product, stripping the molding fixture from the product, and finishing and taking out the product of the compressible material.
