Mold development trend puts special requirements on mold processing equipment

The integration of two technologies promotes the development of the mold industry

Mold is an important process equipment for the forming process of parts. It is an important basic equipment for automobile, motorcycle, electrical appliances, IT electronics, OA office equipment, transportation facilities, building materials and sanitary ware, medical equipment and other manufacturing industries. Since the products formed by the mold have high precision, good consistency and beautiful appearance, they are increasingly used in the manufacture of structures and interior parts of aircraft, ships and high-speed trains. In addition, the production process can achieve high efficiency, large quantities and material saving, and energy saving, so the mold is often praised as the mother of modern industrial production. Luo Baihui, CEO of Mould Network and Deputy Secretary General of Shenzhen Mould Technology Society, said that due to the important role of molds in manufacturing, mold design and manufacturing have become an important area of ​​manufacturing, and mold manufacturing has been developed by various industries in the world. National attention and attention. Due to the characteristics of the mold itself, modern mold enterprises mostly reflect the characteristics of technology intensive, capital-intensive and high-quality labor intensive and high social benefits. The mold manufacturing industry has become a part of the high-tech manufacturing industry. Therefore, the level of mold technology has become an important indicator to measure the manufacturing level of a country, and it is also the core competitiveness to maintain the advantages of these countries' products in the international market.

The Chinese government attaches great importance to the development of the mold industry and mold technology, especially since the reform and opening up, fully affirmed the important basic position of the mold industry and technology in the manufacturing industry and the national economy. Since the reform and opening up, the Chinese government has given preferential support to the development of the mold industry, which has caused fundamental changes in China's mold industry.

1. China's mold industry is basically a capital-intensive, technology-intensive equipment with a large-scale, high-tech industry characteristics, which is mainly based on self-production and self-production within the enterprise and attached to the production of the tooling industry. Manufacturing industry.

2. The production of molds has entered the era of modern industrial production, which is dominated by digital and informational design and production techniques, from the traditional manual production methods dominated by traditional masters and fitters.

3. China's mold industry has developed from a single form of public ownership to a new pattern of private enterprises and multi-ownership enterprises coexisting.

4. The development of the manufacturing industry has driven the development of the mold industry, and the development of the mold industry has given strong support to the manufacturing industry.

At present, China has become a big country in manufacturing, and it is also a big mold producing country. There are 30,000 mold manufacturing enterprises and factories in China, and the number of employees is close to 1 million. In 2009, sales have reached nearly 100 billion yuan, mold imports have reached nearly 2 billion US dollars, and still maintain the import level of 2 billion US dollars for four consecutive years; mold exports are close to 1.9 billion US dollars, which is basically the same as in 2008.

5. The structure of the mold product is more reasonable. The method of forming varies depending on the material of the product. The molds are divided into 10 categories, mainly including stamping die, injection mold, casting die, die-casting die, forging die, rubber tire die, glass die, and the like. The current structural proportion of China's molds: the proportion of stamping molds is about 37%, the plastic molds account for about 43%, the casting molds (including die-casting molds) are about 10%, and the other types of molds such as forging dies, tire molds, glass molds, etc. %. It is consistent with the proportion of mold categories in industrialized countries.

6. The key backbone mold enterprise team has been formed. The production capacity and technical level of a group of enterprises have been greatly improved. Leading enterprises in various mold industries emerged in the development (such as automobile cover moulds - four people, large plastic molds - Haier, Warwick, Quanda, precision stamping molds - Guosheng, Huafu, automobile tire molds - giant wheel , Haomai, casting mold--FAW Foundry, Ningbo Heli, Guangzhou cavity, Beilun Huiwang, precision plastic mold--Weike (Xiamen), Ningbo Henghe, etc.) played a leading role in the industry. 95 mold companies in various mold industries have been awarded the title of “China Key Backbone Mould Enterprise”. During the Shanghai International Mould Exhibition in May 2010, we will award the fourth batch of more than 10 companies. “China Key Backbone Mould Enterprise” "It will be around 110.

7. The company's R&D and innovation capabilities have improved, and new technologies have been promoted and applied. The level of enterprise equipment has generally improved, CNC machine tools such as machining centers, CAD/CAM technology have been widely adopted, and CAE technology has gradually been adopted. Such as the development and application of 3D design technology, research and development application of information management technology, research and development and application of double material (color) injection molding technology, research and development and application of high gloss seamless injection molding technology, development and application of molding technology for plastic steel products , high-strength plate, unequal thickness welded plate stamping forming technology, high-strength plate hot press forming technology, nitrogen spring research and development application, and so on.

8. The mold level has been greatly improved. The proportion of high-level molds represented by large-scale, precise, complex and long-life molds has reached more than 35%. For example, automobile cover molds can produce B-class vehicle complete vehicle molds; precision mold processing precision can reach 0.5 micron; The precision progressive die can be used on high-speed punches of 2000~2500 times/min; the precision of plastic molds reaches micron level, which meets the needs of the development of IT industry; a single set of tire active molds with a weight of 120T and a diameter of 4 meters becomes The largest molds and more.

9. The system for supporting the production of molds is becoming more and more perfect. The mold industry system in China is basically complete and the layout of the mold industry has improved. From the more developed Pearl River Delta and the Yangtze River Delta region to the inland and north, there have been some new areas where mold production is concentrated. There are Beijing-Tianjin-Hebei, Chang (Spring) Da (Lian), Chengyu (Southwest), Wuhan ( Central China), Yuzhong area. However, development is still uneven and regional differences are large. The development of mold agglomeration has become a new feature, and mold parks (cities, gathering places, etc.) are constantly emerging. At present, there are about 15 mold parks that have been built and have begun to take shape in the country. There are also some places where we are planning to build a mold park.

The importance of mold manufacturing in the manufacturing industry has gradually been recognized by people, and it has also attracted the attention of government leaders at all levels. The state has adopted an support policy. Some local governments also support it from all sides.
