1. Constant tension of paying-off with high efficiency and good stability of wire diameter & resistance;
2. Full computer control of process parameters, especially in automatic control of paying-off tension to improve quality of wire winding and stability of products;
3. Internal meter-computing to ensure the accuracy of length;
4. Double motor design without slipping to ensure the consistency of the length of lay and the roundness of the twisted suitable for ultra-thin wire with insulating layer;
5. Automatic laser wire winding to avoid influence on quality owing to human error and downtime.
