In recent years, the development of China’s agriculture, water conservancy, energy, transportation and other industries is very rapid, this requires a large number of machinery and equipment to meet the needs of its development. With the industrialization and the continuous improvement of automation, the equipment supporting the needs of a large number of high performance and high reliability of pneumatic and hydraulic and pneumatic sealing element. Preliminary estimates, is expected to total domestic demand in 2010 of hydraulic, pneumatic and sealing products, will be increased from 20 billion yuan in 2005 to about 35 billion yuan. Among them, hydraulic products from about 10000000000 yuan to 20 billion yuan, hydraulic products from about 1000000000 yuan to about 2000000000 yuan, the pneumatic products increased by nearly 3 billion yuan about 5000000000 yuan, sealing products from about 3000000000 Yuan to 7 billion yuan.

Mechanical engineering is the largest user of hydraulic products, industry sales accounted for 42.3%, the proportion of the future will continue to expand. It is expected that by 2010 the annual demand of hydraulic excavator about 60 thousand ~ 80 thousand, 100 thousand ~ 120 thousand sets about loader, grader roller about 2000 units, about 15 thousand units, about 20 thousand units of crane, forklift about 80 thousand taiwan. In addition, China now has about 1 million 400 thousand units of construction machinery, in 2010 is expected to reach 2 million units.

Each year for the domestic production of excavators, hydraulic machinery, road cement mixer and other supporting imports, more than $150 million. In short, for the engineering machinery maintenance, hydraulic and seal the market will face a new period of development.
