The Features of Sintered Mesh Filter Compared with Traditional Filter
Dec 06, 2025
What does "Sintered" mean?
"Sintered" is a traditional processing technology that refers to heating the powdered materials at a high temperature below their melting point, and forming a dense and polycrystalline sintered body through physical and chemical reactions.
Metal powders will diffuse at high temperature, as the gaps between the powder particles continuously decrease, and the crystal grains grow, the powders will connect with each other and form a compact solid. Sintered mesh filter and sintered porous powder filter are the products which produced by sintering technology.
What is "Sintered Mesh"?
"Sintered Mesh" is made of five to seven layers of woven wire mesh, through a lamination and vacuum sintering into a unit. The material of sintered mesh is usually stainless steel 304/316/316L. The filter accuracy can be customized at a range of 1 -- 300μm, and is uniform and stable, the mesh hole is not easy to deform during the filter working.
Sintered metal mesh has a great performance in high temperature resistance and high corrosion resistance, it can work in a temperature range from -200 to 650℃, and PH 0-14. Sintered mesh can also be washed and reused, it is easy to clean and has a long service life to save the whole cost.
Sintered mesh has a high mechanical strength and high pressure resistance, and it is also easy to mold, process, and weld. It can be processed into various forms of sintered filter elements, such as circular, cylindrical, conical, and corrugated shapes.
Mostly, a whole sintered mesh has five types of layers, including protective layer (80~100μm), separation layer (40~60μm), filter layer (2~20μm), supporting layer (200~300μm), and skeleton layer (thickness 1~2mm). It has been widely used in machinery, chemical fibers, petrochemicals and pharmaceuticals industry according to its excellent filter performance.

Production Steps of Sintered Mesh
Structure Design, Arrangement, and Stacking
According to the filtration requirement, create a reasonable design in precision, thickness, layers, and wire mesh structure of the sintered mesh. Then, the single-layer metal wire mesh is stacked according to the process requirement, and the four corners are spot-welded together to form a sintered mesh assembly.Pressure and Vacuum Sintering
Put the whole sintered mesh into the furnace, and pump out the air in the furnace to maintain a vacuum state inside the furnace. Then increase the temperature inside the furnace to 295-305℃, and inject hydrogen gas to keep the pressure inside the sintering furnace at 39–41 Pa. Start the hydraulic mechanism at the same time to increase the pressure at 0.5-1.5kg/cm² on the sintered mesh, and then continue heating to 1200℃–1300℃ for firing.Cool Down and Take Out
Turn off the heating device and hydraulic mechanism, and rapidly cool the temperature to 1080℃–1120℃ through cooling gas. And then close the hydrogen inlet valve, making the temperature quickly drop to 280℃–310℃ within 15 minutes, afterward cooling naturally to 35℃–45℃. In the end, remove the sintered mesh from the sintering furnace.Final Production processing
According to the usage requirement, doing surface treatment, cutting, polishing and other steps to the sintered mesh.Henan Top Environmental Protection Equipment is a physical factory with 26000 square meters. We have advanced sintering furnace, laser cutting machine, CNC machine tool and other production equipment, and we have strict production process to ensure the product quality.

The Features of Sintered Mesh Filter Compared with Traditional Filter
Material and Production Technology
►The sintered mesh filter element is made of metal wire mesh, like stainless steel and other alloys.►The traditional filter elements for oil or air usually use fiberglass, paper, polyester, PP, and some other composite parts.
Adaptability of Working Environment
►The sintered metal mesh filter is produced through high-temperature sintering technology, and all the connections of the filter cartridge are made using metal welding technology. It has a great mechanical strength, and a good performance in high-temperature and high-corrosion working environments.►The ordinary filter cartridge, like hydraulic oil filter, mostly have a simple structure. And usually use adhesive to connect the end cover. They can only work under normal temperature and pressure working conditions.
Filtration Performance
►Sintering filter cartridge has a high filtration accuracy up to 1μm, it can effectively remove fine particles and suspended solids. Sintered mesh filter has a uniform structure, low resistance to fluid flow, high throughput, and minimal pressure drop variation, so the filtration efficiency is very stable.►Traditional filters have lower filter accuracy and are typically used for pre-filtration or coarse filtration. The pressure difference often increases rapidly, makes them prone to blockages.
Service Life
►Sintered mesh filter can be washed easily, so it can be reused for many times. Even though sintered filter cartridges have a higher price compared with normal filter elements, they have a long service life and can save the whole cost.►Traditional filter elements are mostly disposable or have a short lifetime, and need to be replaced frequently. Have high maintenance costs.
