Extrusion tools for electrical and communication wires

Weilly Diamond manufactures high-precision extrusion tools designed for insulation and coating processes in the production of electrical and communication wires. Each extrusion tip and die is engineered to ensure perfect concentricity, smooth material flow, and long-term stability during high-speed operations.

Weilly’s extrusion dies feature Polycrystalline Diamond (PCD), which provide superior wear resistance and thermal stability compared to tungsten carbide or hardened steel options. The company also offers single- and multi-hole configurations, to fit various production lines.

These extrusion tools are ideal for plastic-coated copper and aluminum wires, telecommunication cables, and data transmission lines. Thanks to the high hardness and low friction of the diamond, they deliver extended tool life, reduced downtime, and higher productivity under demanding manufacturing conditions.
