The analysis of the microstructure of the mold material is of great significance to the quality of the mold, especially for the many brands and models of the mold material, which are shoddy and fake. Microscopic analysis such as the metallographic structure of mold materials and the measurement of coating thickness on the surface of mold parts is in great demand.

Metallographic structure analysis is to measure and calculate the two-dimensional metallographic sample thin film or ground surface through the quantitative principle of metallography, and then obtain the three-dimensional space state of metallographic structure. It is an important means to study the quantitative relationship between alloy structure, composition and properties. . If the metallographic structure analysis technology is combined with the image processing technology, the precision and efficiency of metallographic structure analysis can be greatly improved.
