A device and method enabling industrial continuous pressing, called extrusion of plastically/thermally mouldable substances such as metal, composite metal, plastic, composite or rubber, which is pressed to the profile by a process including a tool fixed member partially predefining the profile shape/cross-section before the profile is finally defined to a cross-section when the material passes rotating dies, which through contact with each other, cancel out main radial forces and the position of which may vary relative to other bearing surfaces or rotary bearing surfaces of the tool with which they define the final shape of the profile. The device and method enable the extrusion of pattern on the inside of hollow profiles and the extrusion of multiple profiles in one tool, because 80-98% of radial bearing forces are eliminated, allowing the installation of rotary dies where not previously possible, and almost unlimited opportunities in increased profile width.
A device for the extrusion of plastically/thermally deformable material to one or more profiles of fixed or variable cross section, the device comprising a static parts matrix coupled with multiple inner rotary dies, said inner rotary dies at least partly defining a profile cross-section and variation, wherein surfaces of said inner rotary dies are in direct contact with each other so as to allow a transfer, and facilitate a cancellation, of opposing radial forces acting on said inner rotary dies from said plastically/thermally deformable material.
