The domestic rubber seal companies have not been very clear about their own positioning, blind production, lack of matching and cooperation with the host company. It can be said that most of the domestic seal company’s products are only mass-produced according to the same standards. They don’t care whether their products can meet the matching requirements of the host products on the market, and they are looking for their own factory quantities.

However, it is difficult to ensure the mechanical stability of the host. Although the work has been opened in recent years, but these are still far from meeting the needs of other work to open up the standardization and serialization of various types of rubber seal products, especially in comparison with international advanced countries. Product quality is still in the product category, there is a considerable distance.
The overall work output value of the seal work cannot be confused with the mechanical work of the national leader. However, the seal has a serious impact on the overall function and service life of the mechanical equipment. Therefore, it is only necessary to continuously produce excellent seal products, and it is very good to promote the development of mechanical work.
