By simply changing the extrusion die, the same line can produce copper busbars of various widths\/thicknesses, flat wires, round wires, and custom profiles.<\/p>\n\n\n\n<p><strong>Is continuous extrusion suitable for high-volume cable conductor production?<\/strong> <\/p>\n\n\n\n<p>Absolutely. With outputs ranging from several hundred to over 4,000 kg\/h depending on model, and the ability to run continuously with automatic take-up, it is ideal for industrial-scale copper wire and busbar manufacturing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion &amp; Next Steps<\/h2>\n\n\n\n<p>Le <strong><a href=\"https:\/\/doingcable.com\/fr\/\">processus d'extrusion continue<\/a><\/strong> represents a mature, high-performance solution for modern copper conductor manufacturing.
