Zhejiang Jiashan metal stamping parts, what are the raw material properties of stamping parts + hundreds of processing and production equipment

The stamping technician in charge of the hardware of the Zhejiang Jiashan hardware stamping parts manufacturer said that the raw material properties of the metal stamping parts have the following knowledge, the following hardware masters will take everyone to understand: 　　1, chemical analysis, metallographic inspection and analysis The content of chemical elements in the material determines the level and uniformity of the grain size of the material, evaluates the level of free cementite, banded structure and non-metallic inclusions in the material, and checks the material for 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 focus on Zhejiang Jiashan hardware stamping parts, 20,000+ sets of customized stamping die production experience, monthly 100+ sets of mold processing capacity, hundreds of precision processing production equipment, daily production capacity of 3 million punches, silk-like stamping accuracy Up to 0.01mm, raw materials are imported and national standard original factories, 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 to rest assured!
