✦ Synopsis
Die-less drawing, introduced in connection with wire drawing (M. S. J. Hashmi, G. R. Symmons and H. Parvinmehr, J. Mech. Engng Sci. 24, 1-4 (1982)) is a process in which reduction in the wire size is achieved by hydrodynamic action. In this system, the conventional die is replaced by a reduction unit of stepped bore geome~:ry. Polymer melts are used as the pressure medium, which, when dragged through the unit by pulling the wire, give rise to drag force and hydrodynamic pressure. The combined effect of these forces cause plastic deformation in the wire. The technique has also been applied to strip drawing (A. H.
