Recently DFE had the opportunity to work with an internationally known wire and cable manufacturer providing tension control for an insulation extrusion line. The machine in question applied a foam insulation to a single center conductor which would later be covered with a braided shield to form coaxial cable.

The process in question was a line used to apply insulation to the center conductor of coaxial cable. It consisted of a wire supply fed to an infeed capstan with multiple wraps, from the capstan the wire is fed to an idler and then through an extrusion die for application of the foam insulation. From the die the product is fed to a cooling trough, and then around a pull capstan (again multiple wraps) and to the winder.
