A pressing head (100) for a device for pressing material to be pressed, e.g., an extrusion press for pressing chips. The pressing head (100) comprises at least two pressing channels (1, 1), each having an inlet opening (11, 11) and an outlet opening (12, 12). Each pressing channel (1, 1) has a stationary supporting element (2, 2) and a movable pressing element (3, 3). The pressing element (3, 3) is movable on one side, preferably relative to the supporting element (2, 2). A cross-section (QA) of the pressing channel, at the outlet opening of the pressing channel, can be varied relative to the cross-section (QE) of the pressing channel, at the inlet opening of the pressing channel.

A system and method for an improved material flow through an extrusion machine by altering the material properties in a magnetic field are provided. The electromagnetic extrusion system includes a ram that is moved into a chamber containing an extrusion material to force the extrusion material out of an opening defined, at least in part, by a die to create an extrusion with a cross-sectional shape corresponding to the predetermined shape of the opening. An electromagnetic winding of electrically conductive material is embedded within a tool retainer block surrounding the container and is helically wound about the chamber and carries a DC electrical current to generate a magnetic field having a magnetic flux density of at least 2 Tesla within the extrusion material to dissipate dislocation defect structures in the extrusion material being extruded via the magnetoplasticity effect. The magnetic field therefore provides for reduced flow stress on the tooling.

A piston includes: a base body; a sealing ring provided at an outer peripheral surface of the base body and configured to slidingly contact an inner peripheral surface of a container; a pressing body provided at one side of the base body in a non-hermetical state with respect to the container, the one side being close to a fluid; and a supporting member supporting the pressing body in a state where the pressing body is separated from the base body. The base body includes an air discharge hole through which an inside and outside of the container communicate with each other, the inside and outside of the container being sealed by the sealing ring. The pressing body can approach and separate from the base body between a first position at which the pressing body opens the air discharge hole and a second position at which the pressing body closes the air discharge hole. The pressing body is supported by the supporting member at the first position and moves to the second position by force applied from the fluid in the container.

The proposed solution solves a problem of designing a machine for producing molded composite parts that are homogeneously structured and the problem of finding a method for producing composite for implants. The essence of the design of the machine consists in that it has a portioning assembly, whereby above a mold form unit (14) there is a guiding unit (11) located opposite a dosing unit (6) and above the aforementioned guiding unit (11) there is a pressing assembly (20) slidingly mounted on a vertical frame (19) and which is equipped with at least one piston rod (25) with a rammer (27) at its end.

A preliminary molding is being performed by thoroughly filling a preform trough and then the matter is being pushed out of the preform trough in portions and then each portion is rammed separately until consistency containing less than 15% air is achieved.
