At present, the company is the exclusive tire at the same time have the structure of the two-mode (inclined plane-oriented structure, cone-oriented structure of the surface) are two processes (steel engraved design technology, precision casting technology of aluminum alloy) and manufacturing technology of the first all-electric Die spark processing enterprises. Enterprises have been adopted comprehensive CAD / CAE / CAM technology, and formed a corporate LAN. In 2004, the Company's shares listed on the Shenzhen Stock Exchange, opened a private dies business listed on the stock precedent. The use of funds raised by the stock market, the company introduced a number of internationally advanced level of technical equipment to further enhance the production company active tire mold levels and abilities.

In the 1990s, Die Co., Ltd. in Anhui Prince fine with South Korea co-production of mosaic-style decals all-steel radial tire mold and mold expert to hire Korean company, will soon produce qualified mosaic-style all-steel radial tire mold. 4-year cooperation period, the company has fully mastered the technology of production of its mosaic-style decals tire mold has been part of the exports. Road Co., Ltd. in Anhui die in the beginning of this century have mastered the technology, developed and created a mosaic-style decals active tire mold.

In 2003, the day Yang Rubber Machinery Co., Ltd. changed its name from the days of Guangdong Yang Dies Co., Ltd. successfully developed China's first large-scale engineering radial tire mold active, in 2004 through the identification, filled the gap, but also in the 2002 to 2004 Six years by national patent. State authorities in 2002, the company's production of "Swan" brand tire mold active as "well-known Chinese brands." The company, "Yang-day" brand to declare Die is a trademark of the country.

State of the industry and major manufacturers

In 2003, the national 13.8 percent growth in tire production, in which radial growth of 27.3 percent, the all-steel radial truck radial growth of 59.7 percent. In 2004 and 2005, and all-steel radial truck radial tire for an average annual growth rate of 25% and 30% respectively. Highway Yanzhua overloading, so that the bias tire of the pick-up in demand. Each year about 50 new models, so that the child have a large number of semi-steel demand. Tire industry determines the tire rubber mold industry.

In recent years, the Chinese tire industry and healthy development of the mold, which marked the major industry restructuring and accelerate the pace of enterprise restructuring, the rapid development of production, mold design and manufacturing standards further improved. Rubber tire molds to be prosperous middle class, make greater efforts to promote private investment. Rely on technology and technological innovation, new technologies, processes, products are emerging to enable enterprises to speed up the tire mold to the high-tech enterprises into the pace. Now, the production of rubber tire mold of a total of more than 100 enterprises, which have reached a certain scale of a total of more than 30 enterprises, of which 200,000,000 yuan in the production capacity of more than two enterprises: Guangdong wheel Die Co., Ltd., Shenyang days Jieyang City Die Limited. 100,000,000 yuan with an annual production capacity of more than two enterprises: Shenyang Radial Tire Mold Co., Ltd., Shandong Machinery Co., Ltd. high-density die. Zhangjiagang, China United Rubber Machinery Co., Ltd., Jiangsu, China and Libya die factory, Anhui prince fine tooling, die Road Co., Ltd. in Anhui, Henan Global Die, Die Tire Co., Ltd. Shaoxing County, Shaoxing Zhengxing Die Co., Ltd., Shanghai Tire Life Dies Co., Ltd., Qingdao Rubber Machinery Factory, Tianjin Tianma Die Co., Ltd., Tianjin TRW Die Co., Ltd., Zhongshan, Guangdong mold factory, Changzhou Wujin Taihu Die Co., Ltd., Shenyang Air Die Co., Ltd., more than 10 tire manufacturers also die Have created a large-scale production capacity.

The main type of rubber tire molds for the tire mold active, 2 Die, Die capsule and drum forming four main categories. Among active tire mold highest technology, the most difficult to develop the best prospects for the current type of mold can produce only 10 more than the country.

The main problems and prospects

China's rubber tire mold manufacturing enterprises have developed rapidly though, but the level and scale of the disparity, even at the forefront of the enterprise, with similar foreign companies, particularly in Europe and the United States, there are a wide gap between the lack of international competitiveness. The reason why there are three reasons. First, technological innovation and poor, has yet to develop a comprehensive manner targeted research and development system and mechanism. Second, the lack of qualified personnel, in particular the lack of cutting-edge high-level talent. The third is relatively backward technology and equipment, numerical control equipment not only of the low rate, and the existing equipment, numerical control the quantity and quality of foreign countries and have a larger gap.

With the rapid development of the auto industry, tire business-to-die accuracy, quality, delivery, and life is demanding higher and higher die competition among enterprises has also increased. To face the new situation, how to deal with mold is also a major problem.

In the face of the "11th Five-Year Plan" period of rapid development of the tire industry, the rate of meridian tires and continuous improvement in the current production capacity of tire mold, especially in active tire mold a serious shortage of production capacity, which is rubber tire mold industry is facing a major problem Moreover, there is a problem in the international market.

In the face of good market prospects and the main problems, China's rubber tire molds enterprises must enhance the core competitiveness and innovation efforts. To this end, the following should be taken active measures:

To increase investment and improve the standard. To diversify funding sources, both inside and outside the technology should enhance the use of new technologies and advanced technology.
To speed up enterprise reform and to change the pace of establishing a modern enterprise system as soon as possible, to adapt to the market.
Establishing a scientific concept of development, good corporate governance.
Actively training and strive to improve the quality of staff and multi-channel solution to a lack of IT personnel, in particular the lack of cutting-edge talents.
To promote all-round digital, information technology, innovation and the establishment of a mechanism, using a variety of ways to improve the ability to innovate.
Do a good job in the standardization work. Tire rubber mold of standardization is a weak link as soon as possible to raise the level of standardization to increase the use of the standard coverage.
