Glossary explanation of common defects in metal stamping parts

When stamping parts manufacturers produce and process metal stamping parts, some undesirable defects will inevitably appear, which will affect the quality of stamping parts. So what are the specific defects, let us explain the common defects of metal stamping parts. 1. Deformation: refers to the appearance and shape variation caused by many reasons; 2. Oxidation: refers to the chemical change between the material of the metal stamping parts and the substances in the air, loss of original characteristics, rust, etc.; 3. Scratches /Scratch: Refers to the damage caused by contact and friction on the surface of the metal stamping parts; 4. Flap/burr: refers to the residual uneven edges caused by shearing or stamping; 5. Crack: refers to the metal stamping parts The material is partially broken, typically there is a fracture on the outside of the bending and drawing process; 6. Concave and convex marks: refers to abnormal protrusions or depressions on the surface; 7. Die marks: usually the production of such marks is related to imprinting and stamping Forming related; 8. Die: refers to the defects caused by punching, stretching or poor unloading during the processing of stamping parts; 9. Material discrepancy: refers to the use of non-designated metal stamping parts materials; 10. Stain : Most of the defects are caused by unidentified oil stains or dirt adhesion during the processing; 11. Missing process: refers to a process that is missed during the processing of stamping parts.
