Oxygen-free copper rod feedstock is fed into a precision-grooved rotating extrusion wheel. Intense friction and controlled pressure generate localized heat, bringing the material into a plastic state where dynamic recrystallization occurs. The material then flows into the die chamber and exits as finished high-conductivity product of unlimited length in a single, continuous operation \u2014 without the need for preheating or post-extrusion annealing in most applications.<\/p>\n<p dir=\"auto\"><strong>Key advantages for copper processing:<\/strong><\/p>\n<ul dir=\"auto\">\n<li>Preserves and enhances the inherent high conductivity of oxygen-free copper<\/li>\n<li>Produces soft temper material ideal for direct bobbin take-up or further forming<\/li>\n<li>Excellent bendability and formability for complex busbar shapes used in EV and switchgear<\/li>\n<li>Significantly higher material yield and lower energy use than traditional routes<\/li>\n<\/ul>\n<h3 dir=\"auto\">Caract\u00e9ristiques d&#039;ing\u00e9nierie avanc\u00e9es et avantages des processus<\/h3>\n<p dir=\"auto\"><strong>Bande d&#039;extrusion allong\u00e9e et roue trait\u00e9e thermiquement<\/strong><\/p>\n<p dir=\"auto\">Extended dwell time ensures complete compaction and dynamic recrystallization, delivering dense, homogeneous microstructure with exceptional electrical conductivity and long-term thermal stability.
