1. The drawing die of the triangle wire drawing machine will increase the size of the drawing die area 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 wire to be broken by various unpredictable tensions during the wire drawing deformation. This situation rarely occurs when the rod is good.
3. Because the annealing current is not constant during production, the current is suddenly high, and the metal wire is pulled or fused by a sudden strong current during the annealing process.
