Principle

The principle of continuous cladding/sheathing is similar with that of continuous extrusion. Using tangential tooling arrangement, the extrusion wheel drives two rods into the cladding/sheathing chamber. Under the high temperature and pressure, the material either reaches the condition for metallurgical bonding and forms a metal protective layer to directly clad the metal wire core that enters the chamber (cladding), or is extruded through the space between mandrel and cavity die to form a metal sheath without contacting the wire core (sheathing). Double-wheel cladding/sheathing uses two extrusion wheels to provide four rods to clad/sheath large diameter wire core.
