In recent years, the development of China's agriculture, water conservancy, energy, transportation and other industries very quickly, which requires a lot of machinery and equipment to meet the needs of their development. With industrialization and increasing levels of automation, the equipment needs to support a large number of high performance and high reliability of hydraulic pneumatic and sealing components. Preliminary estimates, in 2010 the total domestic demand for hydraulic, hydraulic, pneumatic and sealing products will increase from 35 billion yuan in 2005 to about 200 million. Among them, hydraulic products from 100 billion to 200 billion yuan, hydraulic products from 10 billion to $ 20 billion, pneumatic products from nearly 30 billion to $ 50 billion, more than 30 billion by the sealing products to $ 7.0 billion.

Construction Machinery is the largest user of hydraulic products, accounting for 42.3% of industry sales, the ratio will continue to expand in the future. It is estimated that by 2010 the demand for hydraulic excavators in approximately 60,000 to 80,000 units, loaders about 100,000 to 12 million units, about 2,000 units graders, rollers about 1.5 million units, about 20,000 units of cranes, Forklift approximately 80,000 units. In addition, China now has about 140 million units of construction machinery is expected to reach 200 million units in 2010.

Annual domestic production of excavators, road machinery, cement mixer, and assorted imported hydraulic parts, about more than $ 150 million. In short, engineering machinery, maintenance of hydraulic and seals the market will face a new period of great development.
