The current production of micro inductors, sensor coils, and micro motors generally faces challenges: large fluctuations in the size of ordinary thin wires, frequent breakage of high-speed winding wires, and easy damage to insulation layers, leading to a decline in finished product yield. The new generation of precision fine wire relies on continuous drawing and precise coating processes, strictly controls wire diameter tolerances, and has high conductor purity and smooth surface; The insulation layer has strong adhesion, stable resistance to friction and voltage. Suitable for large-scale production of fully automatic winding machines, significantly reducing downtime losses, helping coil manufacturing enterprises improve yield rates, and effectively control production costs.
