The production capacity of the new truck radial tire project should reach more than one million; the production capacity of the light truck radial tire project should reach more than 5 million; existing areas with relatively concentrated tire production capacity, such as the eastern coast, will no longer have new projects... It is reported that The "Tire Industry Access Requirements", which has received much attention from the industry, is expected to be formally introduced in the near future and will require new construction projects in terms of industrial layout, scale, technology and equipment, and energy consumption. Inner tube vulcanizers will also set standards for efficiency and related technical indicators. Deng Yaxi, secretary-general of the China Rubber Industry Association, said that the global financial crisis has made the tire industry more clearly see its own problems. Only by properly formulating industry access conditions, industrial adjustment opinions, and the “Twelfth Five-Year Plan†can the tire industry be healthy and stable. development of. It is understood that China has now become a world leader in tire production, and it is also a big consumer of tires and exports. Tire production accounts for about a quarter of the world's tire production. However, the number of tire companies in China is large, the industrial concentration is low, the homogeneity of products is serious, and there are few high-value-added products. According to industry insiders, to change this status quo, to adjust the industrial structure, and to take a high quality, high value-added development path has become an inevitable choice. The upstream industry vulcanizers and inner tire vulcanization technologies raise the specified efficiency standards as the most critical link in the entire industry. Tire equipment wins world recognition The development of China's tire industry began with the introduction of foreign production lines, from digestion and absorption to gradual trials of independent innovation. Among these, as the most critical production line of the production line, China has already completed the road to localization well and has become one of the few countries in the world that can provide a full set of production equipment for passenger cars, passenger cars, passenger cars and construction vehicles. . He Hailiu, Secretary General of the Technical Committee of the Tire and Automotive Rubber Products of the China Automotive Engineering Society, told reporters that at present, the production equipment for tire equipment, especially radial tires, has basically been localized, with the exception of relatively key and core equipment such as vulcanizing machines. With the core technologies such as material machines not yet fully understood, the localization rate of other radial tire production equipment is already very high. As one of the important basic equipments for tire production, rubber machinery provides guarantee and support for the development of China's tire industry, and it is recognized as one of the best industries in the equipment industry. In the initial period of reform and opening up, most of China's radial tire manufacturing machinery was mainly imported, supplemented by domestic production. However, at present, most domestic tire machinery is not inferior to foreign products in terms of technical content, appearance, intrinsic quality, and performance. It is not only adopted by domestic tire factories, but also large overseas tire companies have begun to purchase large quantities of Chinese rubber machines, prompting the manufacture of foreign rubber machines. The business drastically reduced the selling price. Zheng Yusheng, senior engineer of the National Rubber and Plastics Design and Technology Center pointed out that at present, more than 90% of China's tire production equipment is made domestically, and in particular, it is the world's leading level. However, on the other hand, China still has shortcomings in the key technologies of tire equipment. This is mainly reflected in the testing and testing equipment, and there is still a gap with the international advanced level. Experts said that China's rubber machinery and tire industry are rooted in the Chinese market, the tire industry's huge demand for equipment, promoted the development of the rubber machinery industry; the development of rubber machinery has also promoted the progress of the tire industry and to the world. However, in order to achieve the transition from the world's largest tire country to a strong country, China still needs to speed up and strengthen the rubber machinery industry while expanding. Continuous breakthrough in process technology From the rubber planted in the rubber plantation to a tire that can be mounted on a car, the number of processes that go through in the end may differ. Different tire products may have different requirements, but in general, radial tires are subject to preparation of rubber material, The main manufacturing processes include calendering, preparation of tire semi-finished parts, bead preparation, tire molding, tire vulcanization, and finished product inspection. Huang Qiang, deputy director of the Department of Science and Technology of the Beijing Rubber Industry Research and Design Institute, said that at present, domestic tires have been fully mastered in the general products of semi-steel radial tires. However, at the core of the technology, mainly in terms of tire structure, formulation, etc., there is still a big gap with the top foreign manufacturers. Zheng Yusheng believes that at present, the world's eight major tire brands have established factories in China, and many technologies have been introduced to form a shared, so the technology of domestic tires has been rapidly improved, and the gap with foreign countries is getting closer and closer. However, in terms of talents and product formulations, there are still significant gaps. In particular, the reserve of talents and the quality of personnel must be urgently improved. “Now the quality of domestically produced tires is not worse than that of foreign countries, and some are even better than theirs.†Wang Mingjiang, chairman of Jiangsu Jiangyin Tire Co., Ltd., believes that: “At present, the overall production technology and equipment of domestic tire companies still have R&D capabilities. The difference in foreign countries is that we only have social visibility and brand influence." Not only has production technology continued to make breakthroughs, domestic tires in the production process have also made significant progress. “The production process of domestically produced tires is similar to that of foreign first-class brands. Everybody is basically following the same process in manufacturing. However, in terms of details, domestic tires are still not enough, and the control of each link is not as good as that of foreign first-class brands. On the other hand, the top brands in foreign countries are more reasonable in the coordination and matching of production equipment and processes. It should be said that the formula process is very important for product quality. These are very detailed studies and require long-term investment.†National Rubber Tires Ma Liangqing, deputy director of the Quality Supervision and Inspection Center, said. Automobile tires are composite products of rubber and fiber materials and metal materials. The manufacturing process is a comprehensive process of mechanical processing and chemical reactions. Any deviation in the control ability will affect the quality of the final product. Therefore, it is necessary not only to master the production process and process, but also to grasp the core manufacturing technology and formula. "The gap between the production process and technology is mainly reflected in the details. For example, foreign products can be made very thin, so as to achieve the purpose of saving plastic and reducing costs. Domestic tires may not be as thin as foreign ones; There are gaps in some of the major key technologies, including high-temperature vulcanization and low-temperature mixing, such as atmospheric vulcanization, which has been popularized abroad, but China has only just begun, and there are some subtle gaps in automation. The gap is getting smaller and smaller, and core technologies are being mastered more and more." He Hai left. “After more than ten years of study and technology accumulation, we have continued to invest in our own technology research and development. At present, the overall technical quality of inner tube vulcanizers produced by Sanming De'an Chemical Equipment Co., Ltd., and the data parameters of all inner tube vulcanizing presses have reached the international advanced level. In particular, the overall level of card bus inner curing press has surpassed the international advanced to reach the world's leading level. Therefore, the subsequent development of China's tire industry still has great development advantages under the support of a powerful Chinese machinery industry, said General Manager Zhan Jianlun. Market development requires more support It is understood that at present, 45% of tires manufactured and manufactured in China are used for export, and 1/3 of them are exported to the United States. This indicates that the quality of domestically produced tires has been recognized by the whole world, but on the other hand, both raw materials and markets are out of the market. The development of the tire industry is easily subject to people. Ma Liangqing told reporters that from the quality point of view, domestic tires are not bad at present, and even some products are better than foreign products. In tubeless tires (mainly long-distance bus use), the gap is mainly reflected in the details of stability, wear resistance and comfort; in the case of tube tires (mainly heavy-duty tires), our products are even better than foreign ones. The products are more adaptable in the market, and other products such as agricultural tires and construction machinery tires are also of good quality. The current market gap is more obvious, mainly car tires, the middle and high-end markets are almost occupied by foreign brands. The tire market mainly consists of two parts: the original automobile tire market and the automobile repair market. The market capacity of the latter is three times that of the former. “At present, in the domestic market, car tires are still dominated by foreign brands, but the status of domestic tires is gradually being strengthened. An important reason why foreign tires are dominant is that they have natural advantages in terms of matching, which is in line with the development of the automotive industry. Closely related. But in the retail market, domestic tires are becoming more and more recognized. In addition, in terms of truck tires, domestic tires have taken the initiative," said Zhang Keshun, director of the Shandong Linglong tire planning division. Ma Liangqing suggested that we should start with government procurement, increase support for domestic tires, use domestic brands to stimulate domestic demand, and promote the development of domestic tires. At the same time, domestically produced tires also have to follow the development path suited to China's national conditions. In particular, they have developed more products that are suitable for the road conditions in China to occupy the market and gain the trust and support of consumers. Deng Yaxi said that the simultaneous development of both domestic and foreign markets has always been the goal of China's tire industry. Under the background of China's expansion of domestic demand, domestic tire companies should pay more attention to the domestic market in order to achieve greater results.
