MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202647112576 A) filed by Circmet As on September 18, 2026, for An Extruder Device And Method Of Controlling The Extrusion Pressure.
Inventor includes Werenskiold, Jens Christofer.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: An inverted extruder for extrusion of materials with high viscosity, such as aluminium, aluminium alloys, or other metal matrix composites or alloys, comprising a housing (15) having a bore (16) extending between a feeding zone (ZF) and an extrusion chamber (18), and an elongate member (14) rotatably arranged in the bore (16) about a central and longitudinal axis (x). At least a portion of the bore (16) comprises a helical recess (10) arranged in the bore wall, and the rotatable member (14) comprises a smooth outer surface or a surface having structural features that promote adherence between the rotatable member and the material which is being extruded. The housing (15) comprises one or more first fluid channels (7) arranged in the wall around the bore (16) and the rotatable member (14) comprises one or more second fluid channels (8). The invented extruder allows for a method of controlling the extrusion pressure by controlling the temperature in the rotatable member (tR) and the temperature in the wall of the bore (tB).
