Hydrostatic extrusion is a process that billets are extruded by pressurized media in a closed container with greatly reduced friction force. During operation a billet is pressurized in all direction by th liquid medium.
When critical pressure reaches dependent upon size of the billet, properties of medium and the shape and the size of the orifice of an extruding die, the billet sets into extrusion process to form final component.

Since the pressurized medium keeps full contact with the billet until the process is complete rather than the billet directly contacts with solid die in conventional extrusion, the friction generated during the process is enormously minimized and almost all energy is directly transferred to the billet, Hydrostatic extrusion can be performed either at room temperature or elevated temperatures depending on materials' mechanical properties. NexTOP Hydrostatic extruder covers extrusion forces up to 1,000ton utilizing wire-wound pressure container. Preheating up to 600 ℃ make it possible to operate extrusion process with high strength or hard materials with very high forming speed
