Extrusion of profiles utilising opposite rotating dies
10875069 · 2020-12-29 · ·

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.

20200307059 · 2020-10-01 ·

The present disclosure relates to systems and methods relating to the application of composite radius filler materials. An example material feed system includes a material container configured to contain a composite material and a material feed actuator. The material feed system also includes a nozzle coupled to the material container and a workpiece sensor configured to provide information about a workpiece. The material feed system also includes a controller. The controller is configured to receive, from the workpiece sensor, workpiece information. The workpiece information is indicative of at least one surface of the workpiece. The controller is also configured to, based on the workpiece information, cause the material feed actuator to apply a force to the composite material contained in the material container so as to extrude at least a portion of the composite material out of the nozzle and onto a surface of the workpiece.
