Superior tool concentricity allows wire insulators to meet the demands of today’s super thin-wall constructions.


Extrusion tools are commonly used to apply an insulating layer around a solid or stranded wire. The extrusion tip, also called extrusion wire guide, guides a single or group of wires into and through an extrusion die. The extrusion die controls the shape and size of the insulating material around the wire.


State-of-the-art technology and tight concentricity (0,005 mm) of KIWI® Wire Die extrusion tools give the insulator the ability to maintain a uniform insulation thickness minimizing material usage and scrap.


Super-hard material inserts in the wire guides, primarily diamond and carbide, ensure long tool life even at high extrusion process speeds. KIWI® Wire Die extrusion tools are manufactured with a mirror polish and no sharp edges to ensure optimal insulation material flow and easy threading.


Virtually any extrusion tooling shape for any type of crosshead is available from KIWI® Wire Die.

More throughput, less material usage, less scrap, and higher quality all add up to more profit for the insulated wire and cable manufacturer.
