Sintered Mesh

High-Strength, Multi-Layer Filtration Media for Demanding Applications

Sintered Mesh with Good Mechanical Property for Filtration Applications

Sintered mesh is generally constructed from multiple layers of stainless steel woven mesh after special laminate pressing and vacuum sintering. It is a new type of filter material with higher mechanical strength and overall rigidity, and can be fabricated into filter elements in various shapes, such as round, cylindrical, conical, and pleated shapes. It is a rigid composite filter material made by sintering multiple layers of stainless steel wire mesh at high temperatures. It solves the problems of low strength and poor rigidity of ordinary metal wire mesh, while retaining the high temperature resistance and corrosion resistance of metal materials. Its most prominent features are high strength, stable precision, and reusability after repeated cleaning, making it suitable for harsh working conditions requiring long-term stable operation.

Sintered Mesh Type

All square weave sintered mesh

Typical Applications: sand control screen, Y-strainer tube, automatic filter screen.

It is made of multiple layers of square plain weave wire mesh after sintering. Square weave wire mesh has a square hole opening and a high open area rate, so this sintered mesh has excellent permeability, low resistance, high flow rate, etc. It is widely used in powder handling, drying and cooling and other fields with functional requirements, for example, acting as a sintered mesh candle filter in chemical filtration applications. Square woven mesh features square openings and a high open area ratio. Thanks to these characteristics, square woven sintered wire mesh offers excellent permeability and is more suitable for high-flow applications.

All dutch weave sintered mesh

Typical applications: sparging, fluidizing, powder handling, air drying, etc.

All Dutch weave sintered wire mesh is sintered with two or three layers of plain Dutch weave wire cloth. The layers are elaborately aligned to achieve a uniform pore distribution. Sintered Dutch Woven Mesh offers the finest filtration as well as a firm mesh structure with great resistance to physical loading. The smooth surface is also advantageous for the cleaning process while backwashing.

Standard 5-layer sintered mesh

Typical Applications: Suitable for most micron filtration applications. It can be formed into filter cartridges, filters, baskets/strainers, filter discs, plates, filter cones, and filter tubes.

A standard and the most widely used sintered mesh. It is a combination of 5 layers of wire mesh with different openings and mesh counts after laminating and vacuum sintering. We can also offer 6-layer sintered mesh that adds an 8-mesh or a 12-mesh square weave mesh on the 5-layer sintered mesh to offer higher mechanical strength and compression strength.

Perforated metal sintered mesh

Typical Applications: large diameter nutsche filter disc, big tube screen for automatic filter, etc. (For high-pressure self-support needed applications)

It is fabricated by sintering multiple layers of square weave mesh (or Dutch weave mesh) and stainless steel perforated metal (round or square pattern) together. As a result, it combines the good permeability of woven mesh and the excellent mechanical strength of perforated mesh. The perforated metal can be round hole, square hole, honeycomb, or others. Dead zone (margin) can be designed and retained based on the application. In addition, it has a great backwashing effect and low pressure loss and is widely used in mining, pharmaceuticals, grain screening, etc.

Sintered Mesh Key Features & Benefits

High Mechanical Strength & Rigidity
The multi-layer mesh is fused into a single robust structure through high-temperature sintering. It offers exceptional mechanical strength and pressure resistance, making it easy to weld, cut, and shape. It withstands high differential pressures and pulse impacts without deformation.
Stable Filtration Accuracy
During sintering, the mesh pores become fixed and form a unique gradient pore structure. This enables precise surface filtration while allowing for some depth filtration, ensuring consistent and reliable filtration performance.
Excellent Temperature & Corrosion Resistance
Manufactured from stainless steel (304 or 316L), Sintered Mesh operates reliably across a wide temperature range from -200°C to 600°C. It resists corrosion from most acids, alkalis, and aggressive media.
Superior Cleanability & Regeneration
The smooth pore structure and surface-dominated filtration mechanism allow trapped contaminants to be easily removed through backwashing, ultrasonic cleaning, or chemical cleaning. This enables repeated use and significantly extends service life.
