The continuous rotary extrusion line is especially designed for producing copper alloy trolley wires. The continuous extrusion machine, the key component of the production line, adopts the new die cavity featuring modular construction and high temperature resistance so as to extrude copper alloy products with the tensile strength up to 265N/mm2. Through deep processing one more time, the tensile strength can reach 650N/mm2.

This range of copper alloy trolley wire production line can effectively improve the constitution of extruded copper alloy wires, making the product structure densified and even. Thus, the requirements for high strength and high conductivity can be fully met. Additionally, our continuous rotary extrusion equipment makes use of the new abutment characterized by great strength and exceptional high temperature resistance. For this reason, this continuous rotary extrusion line is capable of manufacturing copper magnesium trolley wire with the magnesium content being 6‰. It is also ideal for extrusion molding of other types of copper alloy wires.
