Our Sintered Perforated Metal Mesh represents the pinnacle of precision filtration engineering, manufactured through a high-pressure sintering process at temperatures between 1,000–1,500°C and pressures of 50–300 MPa. By fusing layered metal powders such as 316L Stainless Steel, Grade 2 Titanium, and Inconel 625, we create a fully interdiffused grain structure that eliminates binder residues, ensuring contaminant-free performance for the most sensitive industrial environments.
Designed for extreme operational conditions, this monolithic structure offers ultra-precise pore sizes from 5µm to 500µm with a strict ±3% uniformity. From ultra-thin 0.1mm foils for microfluidic applications to robust 10mm plates for industrial scrubbers, our sintered mesh provides unmatched tensile strength up to 650 MPa and superior creep resistance, making it the ideal choice for hydrogen compression, subsea oil and gas valves, and aerospace thermal barriers.

| Metric | Standard Woven Mesh | Sintered Perforated Mesh |
|---|---|---|
| Operational Lifespan | Short (Wear-prone) | Ultra-Long (Monolithic) |
| Pore Uniformity | Moderate (±15%) | High (±3%) |

| Contamination Risk | Binder residues possible | Zero (Fully interdiffused) |
| Maintenance Cost | High (Frequent replacement) | Low (High durability) |
Unlike woven mesh, sintered mesh is a monolithic structure formed by diffusion bonding. This eliminates the risk of delamination, provides much higher tensile strength (up to 650 MPa), and allows for ultra-precise pore uniformity (±3%).
We offer Hastelloy® for superior acid resistance and Inconel 625 for high-temperature oxidation. Additionally, optional nanoparticle coatings like Al₂O₃ can be applied to enhance resistance across pH 1–14.
We use a combination of Non-Destructive Testing (NDT), including 100% helium leak testing, X-ray tomography, bubble point analysis, and BET surface area analysis according to ASTM F316 and ASTM E128 standards.
Yes, the monolithic, diffusion-bonded structure is specifically engineered to withstand cyclic pressure loads up to 100 bar, making it ideal for hydrogen recombination cells and high-pressure compression systems.
In biotech and pharma, our sintered mesh is commonly used for sterile venting membranes, bioreactor spargers, and lyophilization chamber components due to its biocompatibility (especially in titanium) and binder-free purity.
Absolutely. Our manufacturing processes and final products are validated to ISO 9001:2015, PED 2014/68/EU for pressure equipment, and NACE MR0175 for sour service environments in the oil and gas industry.
