Abstract: A device and method for designing lightweight, strong, material efficient, extruded and pultruded profiles, profile segments and surfaces produced in profile production with rotating dies creating superior resistance to compression, bending and buckling, higher energy absorption and right strength in the right place, by: varying the thickness along and across the direction of extrusion, making reinforcing patterns varying the profile thickness, and in some cases varying angles and patterns which increases the profile segments/surface resistance against compression, bending and buckling relative to the amount of material used and resulting in the manufacturing of optimized beams and surfaces that have superior properties in terms of strength/weight, stiffness/weight ratio, mechanical energy absorption/weight unit, deformation and natural frequency, thermal transfer capacity, the breaking of the laminar flow, increased/optimized surface for chemical and/or electrochemical reaction etc.

Abstract: 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.

Abstract: A new way to design lightweight, strong, material efficient, extruded and pultruded profiles, profile segments (4) and surfaces produced in profile production with rotating dies creating superior resistance to compression, bending and buckling, higher energy absorption and right strength in the right place, by: varying the thickness along (_t)+across the direction of extrusion, making reinforcing patterns (2, 3), vary the profile thickness (t, _t), and in some cases vary angles (10, 11) and pattern (2, 3) which increases the profile segments/surface resistance against compression, bending and buckling relative to the amount of material used and resulting in that one can make optimized beams and surfaces that have superior properties in terms of strength/weight, stiffness/weight ratio, mechanical energy absorption/weight unit, deformation and natural frequency, thermal transfer capacity, the breaking of the laminar flow, increased/optimized surface for chemical and/or electrochemical reaction etc.

Abstract: The invention relates to device and method enabling industrial continuous pressing, called extrusion of plastically/thermally mouldable substances (11) such as metal, composite metal, plastic, composite or rubber, which is pressed to the profile (12) by a process comprising tool fixed member (6) partially predefining the profile shape/cross-section before the profile finally defined to fixed or varied cross-section when the material passes rotating dies (2) which can be patterned or smooth and through the contact with each other (1) cancel out each main radial forces and the position of which in some embodiments of the invention may vary relative to other bearing surfaces (13, 17) or rotary bearing surfaces (4) of the tool with which they define the final shape of the profile.
