Multi-layer sintered woven wire mesh is a versatile and high-performance material known for its superior mechanical strength, precise filtration capabilities, and excellent resistance to heat and corrosion. This advanced mesh is created by laminating multiple layers of woven wire mesh through a sintering process, which involves bonding the layers together at high temperatures. The result is a robust and durable structure with uniform pore sizes, making it ideal for applications that demand high filtration accuracy and mechanical stability. Common types of multi-layer sintered wire mesh include 3-layer and 5-layer configurations, each offering specific benefits for various industrial needs. Commonly used in industries such as chemical processing, pharmaceuticals, aerospace, and water treatment, multi-layer sintered woven wire mesh provides reliable performance in challenging environments, ensuring effective separation and purification of fluids and gases.

• 3-Layer Sintered Wire Mesh: The 3-layer sintered wire mesh prioritizes efficiency and durability in a straightforward design. It features a fine mesh layer for precise filtration, sandwiched between two coarser support layers that provide exceptional strength. This simple configuration makes it ideal for applications requiring a robust filter media. Common uses include filtering liquids with moderate particle loads or gaseous environments. If you need a reliable filter that excels in both strength and efficient filtration, the 3-layer mesh is a strong choice.
• 5-Layer Sintered Wire Mesh: The 5-layer sintered wire mesh offers a more versatile solution compared to its 3-layer counterpart. It incorporates a fine mesh layer for filtration, supported by additional layers that enhance its capabilities. These may include a dispersion layer for even flow distribution and a cover layer for protection. This multi-layered design strikes a balance between strength, filtration accuracy, and flow management. This makes the 5-layer mesh ideal for demanding filtration tasks like processing fine particles, high-purity liquids, or corrosive fluids. The additional layers provide enhanced performance for applications requiring higher precision and protection from harsh environments.
