With the improvement of the current quality of life, metal stamping parts have penetrated into various fields, and it has been closely related to our lives. As a well-known Custom Metal Stamping Manufacturer, Goodtech will analyze the raw material properties of metal stamping parts.
Raw material properties of metal stamping parts.
1. Chemical analysis and metallographic inspection
Analyze the content of chemical elements in the material, determine the grain size level and uniformity of the material, evaluate the level of free cementite, band structure and non-metallic inclusions in the material, and check the material's shrinkage, porosity and other defects.
2. Material inspection
The materials of stamping parts are mainly hot-rolled or 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 factory can select raw materials for re-inspection as needed.
3. Formability test
Perform bending test and cupping test on the material, determine the work hardening index and plastic strain ratio of the material, etc. In addition, the steel plate forming performance test method can be carried out according to the thin steel plate forming performance and test method.
4. Hardness testing
The hardness test of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be tested with other testing instruments.
