China's agriculture, water conservancy, energy, transportation and other industries developed rapidly, which requires a large number of machinery and equipment to meet their development needs. With the industrialization and automation level, the equipment needs of supporting a large number of high-performance and high reliability of the hydraulic and pneumatic sealing components. Preliminary estimates, by 2010 domestic hydraulic, hydraulic, pneumatic, sealing the total amount of product demand will be 20 billion yuan in 2005 to about 35 billion yuan. Among them, the hydraulic products from more than 100 billion to 200 billion yuan, hydraulic products from more than 10 billion to 20 billion, pneumatic products from nearly 3.0 billion to 50 billion, sealing products from 30 billion to 7 billion yuan.

      Construction Machinery is one of the biggest users of hydraulic products, accounting for industry sales of 42.3, the ratio will be expanded in future. It is estimated that by 2010 the demand for hydraulic excavators was about 60,000 ~ 80,000 units, loaders about 100,000 to 12 million units, the ground plane of about 2000 units, about 1.5 million road roller, construction cranes around 2 million units , forklift about 8 million units. In addition, construction machinery in China now has about 140 million units in 2010 is expected to reach 200 million units.

      In another development, the annual production for domestic enterprises excavators, road machinery, cement mixer, and assorted imported hydraulic parts, some more than 150 million U.S. dollars. In short, the machinery for the engineering, maintenance and use of hydraulic seals the market will face a new period of great development.
