With the improvement of people's quality of life, high -quality small hardware processing has penetrated into various fields, which is closely related to our lives. What are the raw materials for metal stamping process? How do we test the raw material performance of the metal stamping process?

1. Chemical analysis and gold phase test.

Metal stamping parts manufacturers should analyze the content of metal elements in the material, determine the grade and symmetry of the granularity of the material, evaluate the grades of decentralized pearl light, band -shaped tissue and non -metallic mixed objects in the materials, and check the contraction, looseness and other materials of the materials defect.

2. Material inspection

Metal stamping materials are mainly hot -rolled or cold -rolled metal boards and amorphous band materials. The raw materials of metal stamping parts should have a quality certificate to ensure the technical standards that meet the requirements. In the absence of a quality certificate or other reasons, hardware stamping parts can choose raw materials for re -inspection as needed.

3. molding test

The refrigeration index and plastic strain ratio of the material were determined by the bending test. In addition, according to the requirements of sheet metal formability and testing methods, sheet metal forming tests can be performed on high -quality stamping hardware processing.

4. hardness test

Test the hardness of the hardware stamping parts with the lolus hardness meter. Other test instruments can detect small -shaped small metal stamping parts.
