Banan metal stamping parts, what are the raw material properties of stamping parts + 16 strict quality inspections

The metal stamping technicians responsible for the manufacture of metal stamping parts in Banan said that the raw material properties of metal stamping parts have the following knowledge, the following hardware masters will take everyone to understand: 　　1, chemical analysis, metallographic inspection and analysis materials The content of chemical elements in the material, determine the level and uniformity of the grain size of the material, evaluate the level of free cementite, banded structure and non-metallic inclusions in the material, and check the material shrinkage, porosity and other defects.　　2. Material inspection 　　The materials of stamping parts are mainly hot-rolled or cold-rolled sheet metal materials. The raw materials of metal stamping parts should have quality certificates, which ensure that the materials meet the specified technical requirements. When there is no quality certificate or due to other reasons, the metal stamping parts factory can select raw materials for re-inspection as needed.　　3. Formability test 　　 Perform bending test and cupping test on the material to determine the work hardening index and plastic strain ratio of the material. In addition, the steel plate formability test method can be carried out in accordance with the thin steel plate formability and test method.　　4. Hardness testing 　　 The hardness testing of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be tested with other testing instruments. Hardware, 15 years of focusing on Banan metal stamping parts, 20,000+ sets of customized stamping die production experience, monthly processing capacity of 100+ sets of molds, hundreds of precision processing production equipment, daily production capacity of 3 million punches, silk-like stamping accuracy 0.01mm, the raw materials are imported and the original national standard factory, and 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
