Dongguan precision metal stamping parts, the inspection process that makes the results more qualified + 15 years of dedicated experience

Dongguan precision metal stamping parts, before and after the production of stamping parts, need to do a variety of tests to ensure that all aspects are qualified and provide customers with satisfactory results. Xiaoshuo shares a few points with you, let’s take a look: 1. Chemical analysis and metallographic analysis 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 and band structure in the material And the level of non-metallic inclusions, check 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) metal plate and strip 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 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 formability test method can be in accordance with the thin steel plate formability 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 plane is very small, can not be tested on the ordinary desktop Rockwell hardness tester. Hardware, 15 years of craftsmanship focused on Dongguan precision metal stamping parts, 20000+ sets of mold customization production experience, monthly 100+ sets of mold processing capacity, 3 million punching times per day, stamping accuracy up to 0.01mm, and 16 quality inspections strictly. You can quickly solve the time-critical problem of precision stamping parts, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose rest assured!
