Multi-Layer Sintered Mesh
Multi-Layer Sintered Mesh | Stainless Steel Diffusion-Bonded Filter Media
Multi-Layer Sintered Mesh is a high-strength and precision-engineered metal filter medium made by laminating multiple layers of woven wire mesh through a controlled sintering process. During production, several layers of stainless steel wire mesh—each with a specific mesh count and function—are stacked and bonded together in a high-temperature furnace under mechanical pressure. The diffusion-bonding process permanently joins the wires at their contact points, creating a rigid, porous structure with uniform filtration performance and excellent mechanical integrity.
This composite mesh structure is stronger, more stable, and more reliable than traditional woven mesh. It maintains consistent pore geometry, even under high pressure or temperature, making it ideal for demanding filtration and separation applications.
Layer Structure & Composition
The most common configuration is the five-layer sintered mesh, which includes:
- Protective Layer – protects the filtration layer from mechanical damage.
- Dispersion Layer – distributes the flow evenly to prevent localized clogging.
- Fine Filtration Layer – provides accurate filtration of solid particles.
- Support Layer – enhances the mechanical strength of the filtration layer.
- Reinforcing Layer – provides structural stability and load-bearing capacity.
Other multi-layer combinations (three, four, six, or more layers) can be customized according to specific filtration requirements, flow rates, and working conditions.
Advantages of Multi-Layer Sintered Mesh
- High mechanical strength and rigidity – withstands high differential pressure and stress.
- Precise and stable filtration accuracy – uniform pore size distribution ensures reliable results.
- Excellent permeability and low pressure drop – supports efficient flow rates.
- Corrosion, heat, and pressure resistant – suitable for harsh working environments.
- Easy cleaning and backwashable – reusable, reducing operational costs.
- Customizable multi-layer structure – allows tailored performance for various processes.
