In the 21st century, our country has become a big country of mould manufacturing. The sales volume in 2009 is close to 100 billion yuan, and the import of mould is close to 2 billion US dollars, which still keeps the import level of 2 billion US dollars for four consecutive years Die and mold exports nearly 1.9 billion U. S. dollars, is also basically flat with 2008. Hong Kong, the United States, Japan, Germany and India are the countries with the largest number of export destinations of mould. The main export destinations of mould are Guangdong, Zhejiang and Jiangsu, the largest source of mould imports were from Japan, South Korea, Germany, Taiwan Province and the United States, followed by Shanghai, Shandong, Tianjin, Fujian, Liaoning, Beijing and Jilin, the largest number of import destinations are Guangdong, Jiangsu and Shanghai, followed by Tianjin, Beijing, Liaoning, Jilin, Fujian, Shandong and Zhejiang, Hunan and other regions; the national mold production enterprises up to 30,000, nearly 100 million people in the industry, the mold industry, fundamental changes. 10 major changes in our die and mold industry 1, our die and mold industry is basically based on the internal self-production of the main, attached to the product production of the tooling industry, it has developed into a capital-intensive and technology-intensive equipment manufacturing industry with considerable scale and high-tech industry characteristics. The production of moulds has changed from the traditional, locksmith-oriented craft mode of production to the modern industrial production era, where digital and information-based design and production technologies are widely used. 3. The mold industry of our country has developed from a single form of public-owned enterprises to a new pattern of coexistence of private-owned enterprises and various forms of ownership enterprises. 4. The development of the manufacturing industry pulls the development of the die and mold industry, the development of the die and mold industry gives the manufacturing industry a strong support. 5, die product structure more reasonable. According to the material of the product, the method of forming is also different. Molds are divided into 10 categories, the main stamping mold, injection mold, casting mold, die-casting mold, forging mold, rubber tire mold, glass mold, and so on. In our country, the proportion of stamping die is about 37% , plastic die is about 43% , casting die (including die-casting die) is about 10% , forging die, tire die, glass die and other die is about 10% . With the industrial developed country mold category proportion consistent. 6, key backbone mold enterprise team has been formed. A number of enterprises have greatly improved their production capacity and technological level. Leading enterprises in the mould industry have emerged in the development, such as automobile panel mould-the four masters, large-scale plastic mould-haier, Warwick, Qundahang, precision stamping mould-guosheng, Huafu, automobile tire mould-giant wheel, heroic, casting mould-faw casting, Ningbo Heli, Guangzhou cavity, Beilun Huiwang, precision plastic mould-weike (Xiamen) , Henghe, Ningbo, played a leading role in industry progress. The 110 mould enterprises in the mould industry have been awarded the title of“China's key backbone mould enterprises”. The equipment level of enterprises is generally improved, CNC machine tools such as machining centers, CAD/CAM technology is widely adopted, and CAE technology is gradually adopted. 7. The R & D and innovation capabilities of enterprises have been improved, and new technologies have been promoted and applied. Such as the development and application of three-dimensional design technology, the development and application of information management technology, the development and application of two-material (color) injection molding technology, the development and application of Bloom non-trace injection molding technology, development and application of forming technology of plastic instead of steel, stamping forming technology of high strength plate, different thickness welded plate, hot pressing technology of high strength plate, nitrogen spring, etc. . 8, die greatly improved. Large, precision, complex, long-life mold as the representative of the high-level mold proportion reached more than 35% , such as auto panel mold has been able to produce B-class vehicle, mold; Precision die processing accuracy has reached 0.5 micron; precision progressive die can be used in 2000-2500 times/minute above the high-speed punch; plastic die accuracy has reached the micron level, adapted to the IT industry, development needs; a single set of weight up to 120T, diameter up to 4 meters of tire mold to become the largest mold and so on.
