Copper Continuous Extrusion Machine

Our copper continuous extrusion technology is designed for the high-efficiency production of flat wire, round wire, busbar, strip base, and various solid copper profiles. The process utilizes a rotating extrusion wheel that draws copper feedstock into a precision chamber, where friction generates the temperature and pressure necessary for solid-state forming through a die—eliminating the need for billet preheating. With models ranging from TL1250 to TL1630, the platform accommodates feedstock diameters from 8mm to 30mm, delivering output capacities from 160 kg/h to 2,800 kg/h. Product cross-sections span from 2.5mm² to 6,400mm², supporting applications in power transmission, transformer manufacturing, and electrical component fabrication. The system’s continuous operation, high material utilization, and energy efficiency make it a preferred solution for copper profile producers worldwide

Highlights

Solid-State Bonding Mechanism: Achieves metallurgical consolidation through frictional heat and compressive pressure rather than melting, resulting in refined grain structure, enhanced conductivity, and no oxidation-related defects.

Dual-Feedstock Cladding Technology: Employs two aluminum rods fed into a specialized chamber to form a continuous, seamless sheath around a core wire—delivering uniform wall thickness and strong interfacial bonding for high-reliability cable applications.

Modular Machine Architecture: Offers interchangeable wheel sizes (250-630mm), motor ratings (45-600kW), and die configurations to accommodate feedstock diameters from 8mm to 30mm and product geometries including flat wire, round wire, busbar, sector conductor, tube, and corrugated sheath.
