Feature

High-efficiency capacity doubling: By adopting a multi-module synchronous working design (such as simultaneously drawing 8 or 16 fine wires), the output increases geometrically, far exceeding that of traditional single-head drawing machines. Uniform wire quality: The multiple heads are synchronously controlled by the same set of high-precision numerical control and transmission systems. The drawing speed, tension and elongation rate of each head are highly consistent, making it particularly suitable for subsequent braid winding and high-end cable processing. Land-saving, energy conservation and cost reduction: Integrating multi-head drawing, annealing and winding into one unit, the machine body structure is compact, significantly reducing the workshop floor area, and the unit power consumption is lower. Comprehensive cost optimization: Reducing the number of equipment units, the intensity of manual operation and the occupied factory space, effectively lowering the production and manufacturing cost per ton of wire.
