Screw presses designed for forging also hollow pieces. Thanks to a bigger table, it is possible to install special units (horizontal or vertical subpresses) for producing hollow pieces.
Versatility (they may be used also for massive forging), forging accuracy (there is no fixed bottom dead point), high speed, are the specifications of this type of press with respect to the competing ones. It is suitable for forging multiple-way valves and fittings with the possibility to obtain also more than one piece per blow without flash, to meet the most demanding productivity needs. Available capacities from 2300 kN to 14600 kN.
