Industrialists often consider sealing to be a small thing, but sealing is a crucial technological product for the continuous operation of industry. In the early stages of reform and opening up, due to a lack of attention, the sealing industry was always considered a small and diverse field with slow development speed, and a large number of small enterprises were unable to form mass production and quality management. With the improvement of domestic manufacturing level, this situation has begun to change rapidly.

With the rapid development of China's machinery industry, especially the automotive and electronic communication industries, the sealing industry in China has gained irreplaceable practical significance and profound implications for industry development.

In the new international environment, the global manufacturing base for sealing products will continue to shift to China. The sealing industry in China will also usher in a period of leapfrog development and will make greater contributions to the development of China's new industrialization.

According to the statistical data of "Economic Operation Analysis of China's Hydraulic and Pneumatic Sealing Industry", 290 major enterprises in hydraulic, pneumatic, and sealing industries have achieved a comprehensive economic benefit index of 170.81, with 214.97 in the sealing industry, far higher than the national average level of the machinery industry. In the fourth quarter of 2007, the domestic sealing industry achieved a sales revenue of 3.604 billion yuan, an increase of 25.27% compared to the same period in 2006
