Sintered Wire Mesh: The Gold Standard for High-Precision Filtration
Sintered wire mesh is a high-strength, porous metal filter material created by bonding multiple layers of woven wire cloth together through a specialized thermal process. Unlike standard mesh, sintering uses heat and pressure to fuse the wires at every contact point without the need for fillers or bonding agents.
The result is a dimensionally stable, rigid, and exceptionally durable filter medium that maintains its pore size even under extreme pressure and temperature. In 2026, as industries move toward automated, self-cleaning filtration systems, sintered mesh has become the primary choice for “zero-failure” environments.

Core Product: 5-Layer Sintered Wire Mesh Structure
The most popular configuration is the standard 5-layer sintered wire mesh, engineered for a perfect balance of filtration accuracy and structural support.
Protection Layer: Protects the fine filtration layer from physical damage.
Filtration Layer: Defines the micron rating (from 1μm to 200μm).
Buffer Layer: Provides a transition between the fine mesh and the support layers.
Support Layer (Heavy): Adds mechanical strength and prevents deformation.
Support Layer (Heaviest): Ensures the integrity of the entire structure under high-pressure flow.
| Features
Fixed Pore Geometry
Because the wires are fused, the holes cannot "shift" or enlarge during use, ensuring consistent filtration.
High Mechanical Strength
The multi-layer laminate can withstand high differential pressures and back-flushing without tearing.
Easy to Clean
The smooth surface finish allows for excellent "cake" release and can be cleaned via ultrasonic, chemical, or high-pressure backwash methods.
Heat & Corrosion Resistance
Made from high-grade stainless steel or specialty alloys, it excels in acidic or high-heat environments where synthetic filters fail.
No Media Migration
Sintering prevents individual wires from breaking off and contaminating the filtrate.
| Applications
Petrochemical and Oil Refining
Used for catalyst recovery, sand control in oil wells, and filtering corrosive fluids. Its ability to be back-flushed makes it a cost-effective long-term solution for refineries.
Pharmaceutical and Food Safety
Compliant with strict hygiene standards, sintered mesh is used in Nutsche filters, centrifuges, and for the filtration of syrups, beverages, and active pharmaceutical ingredients (APIs).
Polymer and Plastic Production
In plastic extrusion, sintered mesh discs filter out impurities from molten polymers. Its high-pressure tolerance is vital for maintaining the flow of high-viscosity materials.
Fluidization and Powder Transport
Sintered mesh plates are used in fluidized beds to ensure uniform air distribution for the drying, cooling, and transport of powders and granular materials.
Manufacturing & Processing
Commonly used in machinery, extrusion processes, and as support mesh for other materials.

| FAQs
Q1 Can sintered wire mesh be reused?
Yes. Unlike disposable filters, sintered mesh is a permanent filter medium. It can be cleaned and reused hundreds of times, significantly reducing the “cost per liter” of filtration.
Q2 What is the smallest micron rating available?
We can produce sintered wire mesh laminates with a stable filtration rating as fine as 1 micron.
Q3 How do I select the right number of layers?
For most general filtration, 5-layers is the standard. However, for aeration or fluidization, 2 or 3 layers may be better. For deep-well oil filtration, a 7-layer or perforated-metal laminate is recommended.
