Since the reform and opening up ， Our country CNC precision machining Seal industry has made great progress ， Many precision machining factories have set foot in it ， Metal seals, which account for more than half of the industry, have entered a new stage 。 Quite a lot Precision machining Enterprise Seal level of ， Has demonstrated strong competitiveness ， Start to expand the international market 。

　　2018 Year ， China CNC precision machining The market scale of seal industry is about 739.05 Billion yuan ， Industry concentrated in Shandong and Yangtze River Delta ， But Precision machining Enterprise Weak overall competitiveness 。 Future ， Stay Precision machining Driven by downstream industry ， Metal seal manufacturing industry will continue to develop steadily 。

　　 CNC precision machining Seal manufacturing of ， It refers to the sealing parts made of metal Precision machining Production activities 。 Since the reform and opening up ， Through the vast majority of Precision machining Hard exploration of the factory ， Our country CNC precision machining Seal manufacturing industry has fully developed into a competitive industry 。 CNC precision machining Seal industry products are used together with many large industries ， Regardless of aviation 、 Navigation 、 Petroleum 、 Chemical industry ， Or machinery? 、 Electricity generation 、 Metallurgy 、 Mines, etc. ， Seals are inseparable 。 Therefore CNC precision machining Seal industry is small ， But it involves a lot of people 。

　　 CNC precision machining Seal industry development up to now ， Has been from Year Small workshop 、 Small CNC precision machining The workshop or branch of the factory has grown to be basically satisfied China All kinds of equipment requirements 。 At present ， In seal manufacturing ， Metal seal dominant position ， More than half of the market share ， Achieve 71%。 Metal seal ， Occupy CNC precision machining More than half of the seal manufacturing industry 。
