Abstract

A microchannel forming device is provided for making microchannels in a wire. The microchannel forming device includes a plurality of dice for receiving a heated wire spaced along a longitudinal axis. Each die has a circumferential surface forming an opening, and teeth projecting normally from the surface and terminating in the opening. As the heated wire is drawn through the opening of each die, the teeth engage the heated wire to form longitudinal microchannels therein.
