It is embodied in three core dimensions: the implementation of predictive maintenance, the acceleration of product design iteration, and the construction of intelligent operation and maintenance systems, driving the industry to transform from passive replacement to active optimization.

Firstly, the welding of metal sintered filter elements is one of the most crucial steps in their manufacturing process, as it directly affects the filtration performance and service life of the filter elements. During the welding process, high-precision welding techniques must be employed to ensure the roundness and aesthetic appearance of the weld seams, thereby guaranteeing the integrity and stability of the filter elements.

The end cap, as an important component of the filter element, is usually made by stamping or machining processes, and the materials include stainless steel, carbon steel, aluminum and other metals. Its design features include a certain depth of glue injection groove to ensure sealing performance. In addition, the radial end cap is specially equipped with an O-ring groove to further enhance its sealing effect.

Air filters are generally classified into several grades based on their filtration efficiency, such as primary, medium, high, and ultra-high efficiency, with specific standards varying by country.

The types of filter sealing rings are mainly classified by material and structural type. The materials include multiple types of high-molecular materials such as nitrile rubber, fluorine rubber, and silicone rubber. The structural types cover O-rings, V-rings, lip seals, and others.
