The automation production line of coil manufacturing enterprises continues to accelerate, and higher standards are proposed for the tensile strength and surface smoothness of wire rods. Coarse and large tolerance fluctuations in fine wires can easily cause the winding machine to jam or break, restricting the release of production capacity. The surface of XX fine wire conductor is smooth, with uniform tension, and can withstand the impact of high-speed winding pulling, greatly reducing the frequency of equipment shutdown. Multiple coil manufacturers have provided feedback on the replacement of fine wires, resulting in an increase in single line production capacity and a significant decrease in defective products, fully unleashing the production potential of automation equipment.
