Method of moulding metal using high fluid pressure

摘要

A moulding method uses a piston (3;13) for generating high fluid pressures that allow high-precision moulding of complex shapes. The piston (3;13) is slidable in a bore (32) disposed in communication with a mould cavity (8) to generate a high fluid pressure which is applied to a workpiece blank (7;18; 20) to press the blank into a cavity (8) causing it to conform to the shape of the cavity thereby producing an articl (12; 14; 18) of desired shape. <IMAGE>
