What Is Sintered Wire Mesh?
Definition and Core Features:
Sintered wire mesh is made by layering multiple woven wire meshes and bonding them through high-temperature (1100–1300°C) sintering which creates a rigid, durable, and porous metal structure.
Key Structural Characteristics:
- Multi-layer design (typically 5-layer sintered wire mesh)
- High mechanical strength
- Uniform pore size
How Sintered Wire Mesh Improves Performance:
- Eliminates mesh displacement
- Enhances filtration precision
- Improves pressure resistance
Types of Stainless Steel Sintered Wire Mesh?
- Most widely used
- Balancedperformance
- Tailored filtration ratings
- Industry-specific solutions
- Extreme structural strength.
- Outstanding integrity
- High porosity & permeability
- Good dirt holding capacity
Sintered Wire Mesh VS. Traditional Woven Wire Mesh:
Althought both sintered wire mesh and traditional woven wire mesh serve filtration purposes, their mechanical properties and performance under stress are worlds apart. Traditional woven meshs rely solely on the mechanical interlocking of wires; however, this structure is prone to wire migration and pore enlargement under high pressure.
In contrast, our sintered wire mesh undergoes a high-temperature vacuum diffusion bonding process. This molecular-level fusion creates a “monolithic” structure where every contact point of the wire cloth is permanently welded.
Why Sintered Mesh Wins in Critical Applications:
- Structural Integrity: No more “media migration.” The pore sizes remain fixed and accurate even under extreme hydraulic shock.
- Superior Mechanical Strength: Sintered layers (especially with perforated metal reinforcement) can withstand significantly higher pressure drops without collapsing.
- Enhanced Cleanability: Because the surface is smooth and the wires are fused, particles cannot become trapped between overlapping wires, making ultrasonic cleaning and backwashing 40% more effective.
- Heat & Corrosion Resistance: Our 316L sintered structures maintain their filtration precision in environments reaching up to 600°C (1112°F).

FAQ on Sintered Wire Mesh
What is the difference between Sintered Wire Mesh and standard Woven Wire Mesh?
Standard woven mesh is held together by the tension of the weave, which can lead to wire shifting and pore enlargement under high pressure. While sintered wire mesh undergoes a vacuum heat-treatment process that fuses the contact points of all wires. This creates a permanent, rigid structure that maintains its micron rating even under extreme mechanical stress.
Can Sintered Metal Mesh be cleaned and reused?
The answer is Yes. One of the primary advantages of 316L sintered mesh is its exceptional cleanability. It can be restored to near-original performance using:
Backwashing/Backflushing: For liquid filtration systems.
Ultrasonic Cleaning: To remove fine particles lodged deep within the layers.
Chemical/Solvent Cleaning: Since it is highly resistant to corrosion.
Heat Treatment: For organic contaminants.
Which material should I choose: 304 or 316L Stainless Steel?
- 304 Stainless Steel: Suitable for general industrial use where cost-effectiveness is a priority and corrosion risk is low.
316L Stainless Steel: The industry standard for food processing, medical and petrochemical applications. It contains Molybdenum, providing superior resistance to chlorides and acidic environments.
What is the maximum temperature a Sintered Mesh filter can withstand?
Standard stainless steel sintered mesh can operate continuously in temperatures ranging from -200°C to 600°C (-328°F to 1112°F). For higher temperature requirements, special alloys like Inconel, Monel, or Hastelloy can be used to reach up to 900°C.
How do I determine the right Micron Rating for my application?
It depends on the smallest particle size you need to remove. We offer precision ratings from 1 micron up to 200 microns. For high-viscosity fluids (like polymers), a coarser support layer combined with a fine filter layer is recommended to balance flow rate and filtration efficiency.
