China's automotive rubber industry status quo

1 skeleton oil seal

The role of the oil seal to prevent the engine, gearbox, lube oil leak in the train-bridge, as well as external impurities dust into the machine, to ensure that the parts such as bearings and gears work, so as to enhance the car's mileage. Oil seal by the use of sub-site of the crankshaft oil seal (front and rear), the gearbox oil seal, camshaft oil seal, the wheel and axle oil seal, valve oil seal guide and shock absorber oil seal.

Has a domestic scale and level of the skeleton oil seal factory, about 30 more than the total production capacity of about 200,000,000 or so. A major manufacturer in Anhui Ding seals Co., Ltd., 7425 Nanjing plant, factory sealed Zhongqijituan Jinan, Wuxi Rubber Factory, as well as four foreign-funded enterprises in Wuxi Enfu Oil Company, Guangzhou Tirith Austrian oil company, Changchun Enfu oil Feng, Qingdao Kipper Oil Company, Hubei Eastern seals, and other companies.

At present, both within and outside the framework of domestic oil production, oil pressure, oil seals and other fluid dynamics of the structure of the car oil seal, has generally met the needs of the domestic market, but the car key parts of the high-level oil seal, such as the crankshaft after oil Seal, valve oil seals, such as stroke lead still rely mainly on imports.

China's non-tire rubber products import and export statistics, China's annual imports of seal products is far greater than exports. In 2003, for example, imports of up to 252,000,000 U.S. dollars, the export volume was 087,000,000 U.S. dollars, net imports of up to 165,000,000 U.S. dollars. It also reflects the domestic automotive and industrial sealing products can not fully meet the market demand. This requires that the majority of oil producers to further enhance the ability to develop and improve the level of equipment, high-quality products to meet market needs.

2 rubber seal

Sealing is to use its high-elastic material in order to achieve the medium of sealing (dust and waterproof) and isolation (wind, noise, vibration, anti-friction) for the purpose of a class of rubber products. At present, the production of automotive sealing of the more than 60 factories with a total production capacity of 200,000,000 m / year. Major aircraft manufacturers have a stake in your Hongyang seals, seals Hongyang Shanghai Co., Ltd., Zhejiang Serbs Yang seals Ltd., Hebei Xinhua Rubber Co., Ltd., and other seals.

There is a joint venture in Shanghai Shen Ya seals Co., Ltd., Beijing Kang Wanyuan Theis Sealing Co., Ltd., Tianjin Limited Starlight rubber, and so on. In recent years, is a rubber seal of the fastest growing automotive rubber products, has been the introduction of the production line more than 60. Now, domestic high-end cars with rubber seal products, the quality of the automobile industry can meet the matching requirements. However, mid-range cars and trucks sealing tape more quality problems, mainly because production costs in view of the mid-range cars, multi-selection of small and medium enterprises produced sealed, and these companies because of the level of technology and product quality gap is still not ideal, The need to rectify.

3 damping rubber

Damping rubber products used in car engines, car, train and air suspension system. The main products include rubber springs, rubber air springs, shock absorber suspension engine, a variety of purposes, such as shock pad. National has a certain amount of damping rubber production has more than 10 plants, of which there are relatively large birds to Wuxi Co., Ltd. Po shock absorber, Ding seals in Anhui Co., Ltd., Ningbo TOP Plastic Industrial Co., Ltd., Zhejiang Haimen A rubber factory, and so on. There are plastics joint venture in the East China Sea (Tianjin) Co., Ltd., rubber and the East China Sea (Jiaxing) Co., Ltd., Eastern Multimedia Co., Ltd. car seals, Toyota Auto Parts (Guangzhou) Co., Ltd. and so on. National rubber shock absorption, the total production capacity of about 70,000,000.

China's rubber shock absorption through introducing advanced foreign technology and equipment, combined with their own R & D has been able to supply most of the models supporting rubber shock absorption. Some of the more high-performance shock absorber (such as liquid-filled type) of the two companies have successfully developed, marking China's automotive rubber shock absorption has been a certain level of science and technology, but most of the manufacturers, automakers can not meet the Plant at the same time damping rubber research and development work.

4 hose

Automotive hose from the major oil, gas, water and power transmission. The main products are oil pipes, brake hose, vacuum hose, air-conditioner hose, radiator hose, power steering and control Yixing Guan, and so on.

Automotive rubber hose products in high demand, high-performance requirements. A certain production scale of the domestic car companies have more than 20 Hose, with a total production capacity in the S 200,000,000 meters. The production of large enterprises in Shanghai to China's rubber, 7425 Nanjing plant, the rubber company mass Guizhou, Tianjin Dagang Pengxiang Hose Co., Ltd., Jiangsu Taizhou, such as rubber plant. Joint ventures in the larger manufacturers have Goodyear Rubber Co., Ltd. Qingdao project, Dan Ling Yun car wide hose, Eastern Wuhan Limited car rubber, rubber and the East China Sea (Tianjin) Co., Ltd. and so on.

In recent years, China's automobile hose has begun to take shape, many manufacturers have introduced advanced foreign technology and equipment, product quality has greatly improved. Some foreign enterprises to reach the 1990 level. At present, affordable products to meet the needs of the market, high-grade products (such as high-end sedan for supporting some of the products) still need to import. And automotive-related rubber products, rubber hose from the heavy volume of imports is one of the products. In 2003, China's imports hose is 215,000,000 U.S. dollars, exports over the same period was 045,000,000 U.S. dollars, net imports of up to 170,000,000 U.S. dollars. Among them, in order to enhance the steel wire tube, the largest amount of imports, imports of steel wire hose, Germany products accounted for 66.4 percent. Thus it is not difficult to see that in the automotive and industrial hose connection is great potential in the domestic market, which requires the majority of hose manufacturers to further improve the level of production technology, strengthen management, high-performance products to meet the needs of the development of the domestic auto industry.

5 belt

Automotive belt on the main V belt and timing belt, in the transmission of power from the car. V belt for cooling fans, cooling pumps, compressors brakes, power steering pump and air conditioning equipment, such as transmission, V belt is characterized by fast, large power transmission. Timing belt is used for ignition engine valve, the conditions for the use of speed, power transmission, high temperature.

Domestic manufacturers have more than 20. One of the main comparison of public enterprises in Guizhou Rubber Company, Shanghai Belt Co., Ltd., Henan Luoyang and Shanghai Rubber Products Co., Ltd., Ningbo, the Oriental Pearl Co., Ltd. belts, and so on, have a total production capacity of 500,000,000 meters standard. Timing belt, V-ribbed belts of about 20,000,000, there is a joint venture Wuhan Eastern Motor Co., Ltd. rubber products, machine with Bando (Tianjin) Co., Ltd., Tianjin Samsung Machine Co., Ltd. with Gates belt Ni Tower Co., Ltd. and so on.

China's automotive V belt, in particular the timing belt, the production of V-ribbed belts late start, but has developed rapidly in recent years, relied on the basic introduction of foreign technology and equipment as well as to attract foreign investment after developed. At present, basically meeting the needs of supporting the car. Compared with foreign products, product quality and performance are still substantial gaps still need to import some raw materials. From imports and exports, imports large timing belt, V with basically the same as the import and export. Timing belt of the main importing countries and regions are Germany, Japan and Taiwan.
