The wire drawing process imported from Germany Niehoff multiwire drawing machine and advanced automatic computer control system. The production of soft copper wire doubling series of products using raw materials and into the line, Continuous drawing and annealing process , according to different specifications of the product mix, the constant tension produced in the same axis, to ensure the consistency of product performance and excellent surface quality. This series of wire twisting product applications multwire drawing machine and high-speed wire twisting machine use of the device, give full play to advantages of multi-strand wire using up tension automatic control, to ensure that the products of the wire tension and wire diameter, roundness, resistance and stability.
