What are the processing inspection standards for hardware shrapnel manufacturers?

Hardware shrapnel is a relatively common type of metal stamping parts, and it is used in many industries. Because of its wide use, simple production and high production efficiency, there are many hardware shrapnel manufacturers at present, but the processing and inspection work must be done before the products are officially released. So what are the inspection standards? Let's take a look.　　 1. Scratches: The surface of the metal shrapnel should be smooth and free of scratches. In addition, in order to avoid scratches on the surface of the product during packaging and transportation, packaging and transportation must be carried out in accordance with formal requirements. During the handling, pay attention to avoid violent bumps.　　2. Irregular cutting: During processing, due to the process and the positioning is not stable enough, the edge of the product may be cut unevenly. If the edge of the product is not discarded, it is a defective product and needs to be rejected.　　3. Phi Feng: The edges of qualified hardware shrapnel should be smooth and free of burrs. However, sometimes when cutting or stamping, because the process is not well controlled, there may be residual edges on the edges.　　4. Concave and convex marks: If there are abnormal protrusions or depressions on the surface of the hardware shrapnel, they also need to be selected.　　5. Deformation: When processing hardware shrapnel, due to improper equipment adjustment, product deformation will occur after processing. In addition, due to the internal stress of the material, the surface of the product will also be deformed. The deformed hardware shrapnel affects the use, so pay attention to whether the product is deformed during inspection.　　6. u200bu200bScrap: After cutting and stamping, the metal shrapnel is not handled carefully, which leads to the adhesion of metal debris inside.　　7. Stains: The surface of qualified hardware shrapnel should be clean and free of stains. If there are stains, additional treatment is required until the surface of the product is clean and free of stains.
