Quality abnormalities are common among Dongguan shield manufacturers. [Hardware]

In the production process of Dongguan shield manufacturers, the following quality abnormalities mainly occur: 1. The inner and outer surfaces of the product are crushed on the inner and outer sides of the bending. 2. Small hole skipping waste, large hole skipping waste: Long-term production will cause the punch blade wear gap to become larger, unable to jam the waste, and being crushed by the punch surface. 3. Powder crushing: The gap between the punch and the knife edge is too large or too small to cause powder to scatter on the die surface. When the material passes through the leveler and the feeder, the product will be directly crushed by the dust and fine iron filings in the machine. 4. The burr of the small hole cut and the burr of the cut strip. The gap between the punch and the knife edge is too large to cause burrs or the punch is shifted to one side, resulting in burrs on one side and no burrs on the other. The rear process of the shielding cover is made with a cut-and-fold structure, and the punch is worn out after a period of production, and it is easy to produce burrs.
