Hello! Welcome to the official website of Xinxiang Xingda Filter Co., Ltd.!
In modern industrial systems, the purity of fluids and gases is a decisive factor in product quality, equipment longevity, and operational safety. As industries move toward continuous, automated, and sustainable production, traditional disposable filter elements often fall short in handling high-load, high-temperature, or corrosive environments. Sintered wire mesh filter cartridges, engineered through precision vacuum sintering technology, have emerged as the gold standard for demanding applications in petrochemicals, pharmaceuticals, food & beverage, and power generation.
The core of our sintered filter cartridges lies in their multi-layer composite structure. Unlike simple woven mesh, our elements are constructed from 5 to 6 layers of stainless steel wire mesh (typically SUS 304 or SUS 316L) and a support core, fused into a single, monolithic unit via high-temperature vacuum sintering.
Gradient Pore Structure: The layers are arranged from coarse (inside) to fine (outside). This "depth filtration" design captures particles throughout the entire thickness of the media, not just on the surface. This prevents premature blinding and ensures a high dirt-holding capacity.
Mechanical Integrity: The sintering process creates a metallurgical bond, making the filter rigid and capable of withstanding high differential pressures without deformation.
Seamless Seals: The end caps are welded using TIG (Tungsten Inert Gas) welding, ensuring a leak-free seal and preventing any media migration or bypass.
Our sintered filter cartridges are engineered to outperform conventional filters in the most challenging conditions.
Extreme Temperature Resistance: Thanks to the metal construction, these filters can operate continuously at temperatures up to 480°C (and higher with special alloys), making them ideal for hot oil, molten polymer, or high-temperature gas filtration.
Chemical Inertness: Constructed from 316L stainless steel, they resist corrosion from acids, alkalis, and organic solvents, ensuring longevity in chemical processing plants.
Regenerability: Unlike disposable cartridges, sintered filters can be cleaned and reused hundreds of times. They can withstand backwashing, ultrasonic cleaning, and even high-temperature baking to burn off organic contaminants, drastically reducing the total cost of ownership (TCO).
We understand that every filtration challenge is unique. Our manufacturing capabilities allow for high flexibility.
Precision Manufacturing:The picture above display our range of production capabilities, from standard sizes to custom lengths and diameters. The consistent pleating and banding (visible in the images) ensure structural stability even under high flow velocities.
Custom End Configurations: We can fabricate end caps to fit any industry standard connection, including 222/226 O-ring inserts, threaded connections (NPT/BSP), or flanged ends, ensuring a perfect fit for your existing housing.
These robust filters are the workhorses of critical industrial processes:
Polymer & Plastics: Filtration of molten polymers (PET, PP, PE) to remove gels and contaminants before extrusion.
Pharmaceuticals & Food: Used in catalyst recovery, fermentation broth filtration, and beverage clarification. The all-metal, crevice-free design meets strict FDA and GMP hygiene standards.
Hydraulic & Lubrication Systems: Protecting sensitive servo valves and actuators from particulate wear in heavy machinery.
Water & Wastewater: High-temperature sludge filtration and RO pre-filtration in harsh environments.
Sintered wire mesh filter cartridges represent the intersection of material science and advanced manufacturing. They offer a durable, cost-effective, and high-performance solution for applications where failure is not an option.
Whether you need standard replacements or custom-engineered solutions for extreme conditions, our sintered filters are designed to provide you with peace of mind and operational efficiency.
