Customized hardware stamping parts, do you know these technical requirements [Hardware]

For hardware stamping parts customization, not only has the demand for precision higher and higher in recent years, but also the various inspections of stamping factories have become more and more stringent. Xiaoshuo will understand with you: 1. Chemical analysis and metallographic inspection analyze the content of chemical elements in the material, determine the level and uniformity of the material's grain size, and evaluate the free cementite, band structure and non-metallic inclusions in the material Check the material shrinkage, porosity and other defects. 2. Material inspection The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) sheet metal materials. The raw materials of metal stamping parts should have quality certificates to ensure that the materials meet the specified technical requirements. When there is no quality certificate or due to other reasons, the metal stamping parts manufacturer 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 n value and plastic strain ratio r value of the material. In addition, the steel plate forming performance test method can be in accordance with the thin steel plate forming performance and test method. get on. 4. Hardness testing The hardness testing of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be used to test the surface is very small, can not be tested on the ordinary desktop Rockwell hardness tester. Hardware, 15 years of ingenuity and focus on hardware stamping parts customization, 20,000+ sets of mold making production experience, monthly processing capacity of 100+ sets of stamping dies, daily production capacity of 3 million punches, stamping accuracy up to 0.01mm, 16 quality inspections strictly for quality check. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, what you choose is rest assured and worry-free!
