During the production process, fasteners may have out-of-round heads, burrs or burrs on the surface, distortion, cracks and cracks, which are generally caused by the following four reasons:
1. In the process of punching, the choice of punching is not full enough or the choice of punching die is improper
2. The pores are too large during the punching process, the punch rod is too short and the viscosity of the lubricating oil fails
3. Improper machine adjustment and unreasonable mold installation
4. The material itself has quality problems, so the quality inspection must be carried out before the wire is started.
