1. The sizing area of the wire drawing die will become larger due to normal wear during uninterrupted production.
2. Due to the quality problems of various rods. During the production process, the rods have irregular quality defects, which cause the monofilament to be broken by various unpredictable tensions during the wire drawing deformation. This situation rarely occurs when the rod is good.
3. Due to the inconstancy of the annealing current in production, the current is suddenly high, and the single wire is pulled off during the annealing process or fused by a sudden strong current.
