Our country CNC Precision machining Sealing element Our country Machining of mechanical parts Although the seal manufacturing industry develops rapidly ， But Precise Machining of mechanical parts The overall competitiveness of seal manufacturing enterprises is weak 。 From the present Precision machining According to the manufacturing level of seals ， Not enough for the rest Machining of mechanical parts Industry demand for all kinds of sealing products ， Especially compared with foreign metal seals ， Our country Machining of mechanical parts Sealing element Product quality ， In terms of product variety ， There is a considerable gap 。

　　 In fact, at present Precision machining For the individual factory ， We know where the gap is ？ Many Machining of mechanical parts Little change in business ， Production scale turns around ， Some even regress ， Precise Machining of mechanical parts Technology is not updated ， The level of seal manufacturing is constantly weakening 。 And in terms of scale ， Most Precision machining The sales volume of the factory is 500 Below 10000 yuan ，1000 There are not many of them ，1000 There are only a few more than ten thousand ， This makes the domestic Precision machining Factory in metal Sealing element Inferior position in manufacturing competition 。

　　 Despite China Precise Machining of mechanical parts Sealing element There are still disadvantages in the development of the industry ， Vast Precision machining Introduce industrialization into the new round of transformation and upgrading 、 Automated production line ， Yes Machining of mechanical parts A large number of high-performance devices are proposed 、 Requirements for high reliability hydraulic and pneumatic sealing parts 。

　　 In addition to the construction of South to North Water Diversion 、 High speed railway trunk network, etc ， And a lot of big coal mines 、 Power station ， Airport 、 Port 、 High grade highway and other key projects ， And a large number of urban construction and housing construction ， These will make the domestic engineering Machining of mechanical parts Demand will continue to grow for a long time ， Metal seal market will face a new period of development 。
