Products
Sintered Perforated Metal Mesh
Material: Stainless Steel 316L | Titanium Alloy | Nickel-Based Superalloys
Sintering Process: Multi-Layer Diffusion Bonding (Powder Metallurgy)
Pore Size Range: 5μm-500μm (±2μm Precision, Multi-Gradient Layering)
Thickness: 1.5mm-15mm (High-Temperature Structural Integrity)
Porosity: 25%-65% (Controlled Permeability Design)
Surface Treatment: High-Temp Oxidation/Electropolishing/Ceramic Coating
Engineered Precision for Advanced Filtration
Manufactured through high-pressure sintering (applied at 1,000–1,500°C under 50–300 MPa) of layered metal powders—including 316L stainless steel, Grade 2 titanium, and Inconel 625—this advanced mesh achieves ultra-precise pore sizes spanning 5µm to 500µm with ±3% uniformity, validated by scanning electron microscopy (SEM). The controlled sintering process creates a fully interdiffused grain structure, eliminating binder residues for contaminant-free performance in sensitive environments.
Available in ultra-thin foils (0.1mm) for microfluidic devices to robust 10mm plates for industrial scrubbers, it combines adjustable porosity (20%–85%) with exceptional tensile strength (up to 650 MPa) and creep resistance at sustained high temperatures. The diffusion-bonded, monolithic structure ensures zero delamination risk, even under cyclic pressure loads up to 100 bar, making it ideal for hydrogen compression systems and subsea oil/gas valves.
Superior Performance in Extreme Conditions
- Pore Geometry Control: Laser-calibrated apertures with aspect ratios up to 10:1 for directional flow optimization.
- Thermal Stability: Coefficient of thermal expansion (CTE) matched to 1.5×10⁻⁶/°C for seamless integration with ceramic or composite substrates.
- Surface Engineering: Optional electropolishing (Ra ≤0.2µm) or nanoparticle coatings (e.g., Al₂O₃) to enhance corrosion resistance in pH 1–14 environments.
- Non-Destructive Testing (NDT): 100% helium leak testing and X-ray tomography to certify pore integrity per ASTM F316 standards.
Custom Solutions for Critical Applications
- Pore Architecture: Gradient density layers, multi-laminate designs, or asymmetric structures for targeted flow control.
- Material Grades: Options include Hastelloy® for acid resistance, porous titanium for biocompatibility, and bronze-nickel for EMI shielding.
- Form Factors: Discs, tubes, cones, or custom 3D geometries with laser-welded seams (≤0.1mm tolerance).
- Surface Treatments: Passivation, hydrophobic coatings, or catalytic plating (Pt/Pd) for chemical reactivity tuning.
- Testing Protocols: Bubble point, BET surface area analysis, and ASTM E128 pore integrity verification.
- Industry Compliance: Validated to ISO 9001:2015, PED 2014/68/EU, and NACE MR0175 for sour service environments.
Cross-Sector Innovation Drivers
- Energy & Petrochemical: Gasifier filter elements, hydrogen recombination cells, and cryogenic LNG valves.
- Biotech & Pharma: Sterile venting membranes, bioreactor spargers, and lyophilization chamber components.
- Aerospace & Defense: Fuel cell diffusion layers, hypersonic thermal barriers, and radar-absorbing radomes.
- Food & Beverage: CO₂ dispersion plates, fermentation tank filters, and CIP-compatible sieves.
- Automotive: Exhaust gas recirculation (EGR) filters, battery thermal runaway barriers, and EV cooling plates.
