China's CNC precision machining factory in the field of patents has always attached more importance, take the field of seal manufacturing, CNC machining factory has more patents or 2010-2019, China's CNC machining seal manufacturing industry, the number of patent applications climbed year by year, jumped from 2735 to 6810.
Into 2020, the development of CNC precision machining industry tends to be stable, the number of patent applications in the field of CNC machining seal manufacturing slowly declined. 2020, China's CNC precision mechanical parts machining seal manufacturing industry patent applications reached 6508 pieces. And as of 2021, the number of patent applications in China's CNC precision mechanical parts machining seal manufacturing industry is only 3727.
Although China's CNC precision machining seals manufacturing industry has made greater progress, but far from meeting the development of other CNC precision machining industry for various types of sealing products standardized, serialized products, especially compared with the international advanced countries CNC precision machining, China's CNC precision parts machining seals products, whether in product quality, or in product varieties, there is a considerable The gap.
In addition, China's CNC precision machining seals manufacturing industry, the overall competitiveness of enterprises is weak. Although China's CNC precision parts machining seals manufacturing industry is developing at a faster pace, but the strength of CNC machining seals is very slow. In the early 80s, only in Jiang, Zhejiang, Lu there are a few such CNC machining factory, in the present and both coastal, mainland, or the South, North, everywhere you can see seals CNC precision machining factory, the entire CNC precision machining sealing industry has been a few from the previous, the development of more than 900, the development rate is still relatively fast.
