Stamping parts have fully entered our lives. As the use of stamping parts increases, our requirements for stamping parts also become higher.Stamping parts processingThe technical requirements are also increasing. Does stamped part processing have certain material requirements? Let's take a look at the technical requirements for stamping parts processing.

1. Chemical analysis, metallographic inspection.

Analyze the content of chemical elements in the material, determine the grain size grade and uniformity of the material, evaluate the grade of free carbides, banded structures, and non-metallic inclusions in the material, and check for defects such as shrinkage cavities and porosity.

2. Material Inspection

The materials for stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal sheets and strips. The raw materials for hardware stamping parts should have a certificate of quality, which ensures that the materials meet the specified technical requirements. When there is no certificate of quality or for other reasons, hardware stamping parts manufacturers can select raw materials for re-inspection as needed.

3. Forming Performance Test

Conduct bending tests and cupping tests on the material to determine the material's work hardening index n value and plastic strain ratio r value, etc. Additionally, regarding the test methods for the formability of steel sheets, they can be carried out in accordance with the provisions for the formability and test methods of thin steel sheets.

4. Hardness Testing

Rockwell hardness testers are used for hardness testing of stamped hardware parts. Small stamped parts with complex shapes can be used to test surfaces with very small surfaces, which cannot be tested on ordinary benchtop Rockwell hardness testers.

The requirements for materials in stamping parts processing are that a certificate of quality is needed, so that it meets the regulatory requirements. If you are engaged in the processing of stamping parts, you must be aware of some technical requirements for stamping parts processing.
