An experimental press for hydrostatic ultrahigh-pressure extrusion of metals has been designed and built at the VNIIMetmash in cooperation with the Institute of Physics, Academy of Sciences USSR. Numerous problems had to be solved before the design of the press was completed, such as container design, container locking, and deceleration of extruded shapes which emerge from the die at a rate of several hundred meters per second. All these problems were successfully solved. The solutions are not specified but it appears that the container and some other parts stressed by internal pressure are made of or reinforced by a multilayer winding of a high-strength strip or wire. Its relatively small size is a special advantage of the new press. A press now under construction will weigh 50 tons and will be equivalent in performance to conventional 6000-ton presses which weigh more than 500 tons. Author
