Sintered Mesh / Sintered Felt Manufacturer
Sintered Wire Mesh / Sintered Fiber Felt Meaning
Stainless steel sintered mesh sheet is a kind of high-strength porous metal material formed by stacking multiple layers of stainless steel metal woven wire mesh and then consolidating them through a vacuum sintering process. Duplex stainless steel or nickel-based alloys can also be used as raw materials to meet the demands of more corrosive environments. Compared to ordinary wire mesh, sintered metal mesh has a more stable pore structure, higher mechanical strength, and better corrosion resistance, making it suitable for long-term use in harsh conditions such as high temperature, high pressure, and strong corrosion. Stainless steel sintered wire mesh plates are usually delivered in flat sheet form and can be further cut, punched, bent, welded, or processed into various filtration and structural components according to customer requirements.
Metal sintered felt is a three-dimensional porous filtration material made from metal fibers (such as stainless steel fibers, nickel fibers, FeCrAl fibers, and titanium fibers) through a process of web formation followed by high-temperature vacuum sintering. Metal fiber felt’s structure resembles a “felt fabric woven from metal fibers,” possessing high internal porosity, uniform pore size distribution, and excellent permeability. It can operate stably for extended periods under high temperature, high pressure, high viscosity media, and high pollution load conditions. Compared to traditional sintered mesh materials, metal sintered felt offers higher dirt-holding capacity, lower pressure drop, and a longer service life, and is widely used in liquid filtration, gas filtration, and high-temperature dust filtration applications.
Sintered Metal Wire Mesh
The stainless steel sintered wire mesh has 5~7 layers of metal woven wire mesh. Each layer has a different function, allowing for precise control over filter accuracy, strength, and flow rate. The sintered mesh material is easy to mold, process, and weld, making it convenient to manufacture.

Perforated Plate Sintered Mesh
Round hole perforated plate as a support layer, can increase the mechanical strength of the sintered wire mesh significantly. When metal punch plate as a protective layer of the sintered mesh material, is also can prevent large particulate impurities from entering the next filter structure.

Production Process of Metal Sintered Mesh / Felt
Wire Mesh / Metal Fiber Preparation
Select multi-layer woven meshes of different mesh sizes based on the target filtration accuracy, permeability, and strength requirements. / Produce the uniform metal fibers through drawing or cutting processes, and the fiber diameter, length, and purity are screened and graded.
Stacking, Laying and Positioning
Stack and combine the metal wire mesh layers according to the structural design, ensuring the mesh direction and structural stability. / The metal fibers are evenly laid into a felt-like structure to form a three-dimensional porous network of interwoven fibers.
Surface Treatment and Pre-Pressing
The metal wire sheet need to be degreased, acid washed, or ultrasonically cleaned, remove oil and impurities. / The metal fiber felt is pressed to achieve the target thickness, density, and porosity, while also improving structural stability.
Cutting and Further Processing
Laser cutting, water jet cutting, punching, bending, welding, and other processing can be performed to produce filter elements, filter discs, filter plates, or composite filter structures to meet the customer's requirement.
Rolling, Flattening and Straightening
After sintering, Huahang will controls the thickness uniformity and ensures material flatness and mechanical strength of sintered mesh sheet and sintered fiber felt by rolling and flattening.
Vacuum Sintering
High-temperature sintering in a vacuum or protective atmosphere, form a strong metallurgical bond between the layers of wire mesh at the contact points, or at the metal fiber intersections. ultimately forming an integrated multi-layer sintered mesh plate or a structurally stable metal sintered felt.
Features of Metal Sintered Mesh / Sintered Felt
Sintered wire mesh and metal sintered felt have excellent and reliable filtration performance. They feature uniform and stable pore size, consistent and controllable filtration accuracy, excellent permeability, low pressure drop, and multi-layer interception of particles of different sizes, resulting in high filtration efficiency, making them particularly suitable for high-pollution load conditions.
Huahang sintered metal mesh plate and sintered fiber felt have great high-temperature and high-corrosion resistance performance. They can work in high-temperature environments for extended periods, and can filter the acidic and alkaline chemical solvents, seawater, and other media.
