I have done similar things by the following methods
listed in order of difficulty / complexity / setup
1) Coat the wire with silicone or urethane liquid
resin and pull the coated wire through a funnel like
fixture filled with more of the liquid resin that is
attached to compatible tubing.
2) Pull the wire through the comaptible tubing and
use pressure, vacuum or a combination of the two to
fill the tubing with the resin.
3) Pull the wire through the center of a die while
evenly coating it with resin.
