　　I. Integrated Multi-Layer Structure: Designed for Precision and Stability

　　Our sintered filter cartridges feature a three-layer integrated structure, with each layer working seamlessly together to achieve precise filtration and long-term stability. Each layer has a defined function, and their tight integration ensures highly efficient and reliable performance that you can trust:

　　1. Core Filtration Layer (Inner Layer: The Precision Core of the Filter Cartridge)

　　This is the core of the filter cartridge, responsible for capturing impurities of all sizes with high precision and consistent performance. Our filters meet precision filtration requirements thanks to the following key factors:

　　Materials: We use high-purity 304/316L stainless steel powder (purity ≥99.9%) as the standard material. For special applications, bronze, ceramic, or titanium alloy powders are also available. For most industrial applications, 316L stainless steel is the preferred choice—it is durable, versatile, and reliable.

　　Structure: This layer is formed using a high-temperature (800-1200℃) and high-pressure (15-20MPa) sintering process, creating a three-dimensional interconnected porous structure. The pores are uniformly distributed (pore size deviation ≤±5%), and we can also adjust the porosity (35%-55%) according to your specific filtration precision requirements.

　　Reasons for choosing this material and structure: High-purity stainless steel powder offers excellent corrosion resistance, oil resistance, and high-temperature resistance—crucial for handling the harsh environments of industrial media. The sintered porous structure perfectly balances high precision and good air permeability, and its integrated design (layerless or spliced) prevents filter layer detachment, ensuring long-term stable filtration performance. 

       2. Support and Reinforcement Layer (Intermediate Layer: Maintaining Stability)

　　This intermediate layer, tightly fitted to the core filter layer, is designed to enhance the filter's mechanical strength, preventing deformation or damage and maintaining the stability of the core layer even under harsh operating conditions:

　　Material: We use 304 stainless steel support mesh (100-200 mesh) or high-strength polyester retaining rings (10-30mm wide), both offering corrosion resistance matching the core layer.

　　Structure: The stainless steel mesh is nested inside or outside the core filter layer, while the polyester retaining rings are evenly wound around the middle of the filter—both fit tightly to the core layer without any gaps.

　　Reasons for choosing this material and structure: The stainless steel mesh offers superior mechanical strength and abrasion resistance, easily withstanding 5000 cycles of 0-10 bar pressure shocks without deformation. The polyester retaining rings add flexibility, firmly securing the core layer and preventing structural loosening, while also helping to guide filtered oil droplets or liquids, thus reducing the load on the core layer.

　　3. Sealing and Protective Layer (Outer Layer: Leakage Prevention, Performance Protection)

　　As the outermost layer, its function is to seal the filter, prevent corrosion, and protect it from physical damage, ensuring stable operation even in harsh industrial environments:

　　Materials: The housing is made of 304/316L stainless steel (1.0-1.5mm thick). Sealing components (gaskets, O-rings) are made of fluororubber or silicone rubber (Shore hardness 70-80). End flanges are made of stainless steel or high-strength PBT plastic, with a machining accuracy of ±0.02mm.

　　Structure: The stainless steel housing completely encloses the support layer and core layer. Sealing components are installed at the top, bottom, and connection points. The end flanges are seamlessly connected to the housing, forming a fully enclosed protective structure.

　　Reasons for choosing this material and structure: The stainless steel housing has superior corrosion resistance and impact resistance, protecting the internal filter element from media corrosion and physical damage. Fluororubber/silicone rubber seals are oil- and high-temperature resistant, ensuring a tight seal (sealing pressure up to 12 bar, leakage rate ≤0.001 L/min), preventing bypass leakage and maintaining the purity of the filtered media. High-precision end flanges ensure a perfect fit with your equipment, allowing for quick and easy installation.

　　II. Precision Filtration: Reliable Industry-Leading Precision

　　Precision filtration is the unique feature of our sintered filter elements. Thanks to carefully selected materials and advanced processes, we are able to achieve precise filtration.

　　manufacturing processes, and a well-designed structure, we deliver ultra-high precision filtration that protects your downstream equipment and keeps production running smoothly. All our performance indicators are verified by authoritative test data:

　　1. Ultra-High Filtration Precision (Customizable & Measurable)

　　Precision Range: We can customize the filtration accuracy to your exact needs, from 0.001μm to 100μm. For high-precision applications (like electronics, medical, or high-end hydraulic systems), we offer accuracy as low as ≤0.01μm—with a 99.999% retention rate for 0.01μm particles (tested to ISO 16232 standards). For standard industrial use, precision ranges from 1μm to 20μm, with a 99.9% retention rate for 1μm particles.

　　Why We Achieve Such High Precision: The core filtration layer uses high-purity stainless steel powder and advanced sintering, allowing us to control pore size with exceptional precision (pore size deviation ≤±5%). Its three-dimensional interconnected porous structure catches impurities layer by layer—even sub-micron particles—with no leaks, ensuring filtered media stays pure (residual impurity content ≤0.001mg/L for high-precision models).

　　tability Data: SGS testing confirms a 99.8% filtration stability rate, meaning the accuracy stays consistent even during long-term operation—we’ve tested it for 10,000 continuous hours with no precision loss. Our no-bypass leak design (leakage rate ≤0.001L/min at 10bar pressure) ensures all media passes through the filtration layer, so unfiltered media never reaches your downstream equipment.

　　What This Means for Your Business: Compared to conventional filter elements, our sintered filter reduces downstream equipment wear by 40% and equipment failure rates by 35%. It also cuts maintenance costs by 25% and downtime by 30% annually—keeping your production on track and reducing unnecessary losses.

　　III. Fully Customizable: Built to Match Your Exact Needs

　　We know every industry and every piece of equipment has unique filtration requirements. That’s why we offer full customization services—creating a filter element that’s tailored specifically for you:

　　Structure & Material Customization: Based on your filtration media and operating environment, we can customize the material of each layer (core layer: 304/316L stainless steel, ceramic, etc.; support layer: 100-200 mesh stainless steel mesh, etc.; outer layer: 304/316L stainless steel shell, etc.). We also adjust the thickness and structure of each layer to fit your specific working conditions.

　　Precision Customization: Tell us your impurity interception needs, and we’ll customize the filtration accuracy (0.001μm-100μm) to match—no over-engineering that adds unnecessary cost, and no under-performance that risks product quality.

　    Size Customization: Every dimension is customizable, including diameter (50mm-600mm, adjustable in 1mm increments), wall thickness (10mm-40mm, adjustable in 1mm increments), and length (100mm-2000mm, adjustable in 10mm increments).
