Shear Assisted Extrusion Press Apparatus and Components

The present disclosure provides a shear assisted extrusion press comprising a stem and plunger assembly comprising a main piston configured to generate an extrusion force, a stem assembly comprising a stem having a first end and a second end, wherein the second end connects to a rotary piston that connects to the stem and plunger assembly, wherein the main piston exerts the extrusion force on the stem such that the stem moves axially, and at least one piston motor coupled with the stem and configured to drive a rotational movement of the rotary piston and the stem, and a container assembly comprising a container holder, a container configured to receive a billet and the first end of the stem, and at least one hydraulic motor positioned in the container holder with the container, wherein the at least one hydraulic motor is configured to drive a rotational movement of the container. The rotary piston and the stem are configured to rotate and move axially such that the stem moves the billet through the container to extrude a part, and the container and the billet are configured to rotate together while the container does not move axially.
