How to Reflect The Processing Quality of Metal Stamping Tool?

1. Chemical analysis and metallographic examination

Analyze the content of chemical elements in Metal Stamping Tool material, determine the grain size level and uniformity degree of the material, assess the levels of free cementite, banded tissue and non-metallic inclusions in the material, and check the defects such as shrinkage cavity and porosity of the material.

2, material inspection

The material processed by Metal Stamping Tool is mainly hot rolled or cold rolled (mainly cold rolled) Metal plate and band material. The raw material of Metal Stamping Tool should have quality certificate, which ensures that the material meets the prescribed technical requirements. When there is no quality certificate or due to other reasons, Metal Stamping Tool production factory can select raw materials for reinspection as required.

3, formability test

Bending test and cup test were carried out on Metal Stamping Tool material to determine the work hardening index N value and plastic strain ratio R value of the material, etc. In addition, the test method of steel sheet formability could be carried out according to the regulations of formability and test method of thin steel sheet.

4. Hardness test

Rockwell hardness tester was used for the hardness test of Metal Stamping Tool. Small stamping parts with complex shapes can be used for testing with surfaces too small to be tested on a normal bench rockwell hardness tester.

5. Determination of other performance requirements

The electromagnetic properties of the material and the adhesion ability of the coating and coating are measured.

I would like to share the technical requirements of processing Metal Stamping Tool with you here. In addition, it should be noted that the precision and surface state of hot Metal Stamping Tool are lower than that of cold Metal Stamping Tool, but they are still better than that of casting and forging, and the cutting processing amount is less.
