Mold industry analysis in recent years
1. From the global observation of the development of China's manufacturing industry, it can be seen that China's manufacturing industry has developed rapidly in recent years. For the CNC bending machine mold industry, this means a huge market. In this context, China's low level of manufacturing costs is a recognized fact. From the perspective of labor productivity, statistics show that compared with developed countries such as Germany, the United States, and Japan, the gap between China and Germany, the United States, and Japan is about 3 to 5 times. Such a large market, low level of labor productivity, coupled with the continuous progress and development of manufacturing technology, are both opportunities and challenges for the CNC bending machine mold industry. The market demand for CNC bending machine molds is not only the growth of quantity, but also the improvement of quality. From the perspective of user industries, there are seven industries that have the most significant demand for CNC bending machine molds.
2. From the perspective of the development process of CNC machine molds, from the end of the nineteenth century to the middle of the twentieth century, high-speed steel was the main representative of CNC bending machine mold materials; in 1927, Germany first developed carbide CNC bending machine mold materials and obtained Widely used; in the 1950s, synthetic diamond was synthesized in Sweden and the United States, and the cutting of CNC bending machine molds has since entered a period represented by superhard materials. In the 1970s, polycrystalline diamond (PCD) was synthesized by high-pressure synthesis technology, which solved the problem of scarcity and high price of natural diamond, and expanded the application scope of diamond CNC bending machine molds to aviation, aerospace, automobile, Electronics, stone and other fields.

3. The selection of CNC machine mold materials is the basis for successful cutting. Compared with cemented carbide, the die speed of PCD CNC bending machine can reach 4000m/min, while cemented carbide is only 1/4 of that. In terms of service life, PCD CNC bending machine molds can generally be increased by 20 times. From the surface quality of the processed, the effect of PCD is 30% to 40% better than that of cemented carbide. In addition, the development of CBN (vertical boron nitride) superhard material CNC bending machine molds and surface coating CNC bending machine molds also contributed to the advancement of cutting technology. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. A tool used to make a blank into a part of a specific shape and size under the pressure of a bending machine.
