Sintered mesh
Strength in layers.
Multi-layer woven mesh, sintered into a rigid porous laminate: precise pores, high strength and a filter that can be cleaned and reused.
Sintering bonds several layers of woven wire cloth at every wire crossing, turning flexible mesh into a rigid, fully porous plate. The result combines the precise pore size of fine cloth with the strength of coarse support layers: no migration, no mesh deformation under pressure peaks.
By engineering the stack (protection, filter, distribution and support layers), pore size, permeability and stiffness are tuned per application. Graded (gradient) pore structures increase dirt-holding capacity and stretch cleaning intervals, which is exactly what minimum downtime looks like in practice.
Averinox supplies sintered laminates as panels, discs, cones, cylinders and complete welded elements, with application analysis and material advice included. Sub-micron ratings down to 0.5 µm are available for polymer, gas and high-purity service.
Applications
- Polymer melt filtration (high-viscosity, high-pressure)
- Hot gas and catalyst recovery filtration
- Hydraulic and lubrication oil cleaning
- Fluidising plates and spargers in powder processing
- High-purity steps in food, pharma and hydrogen systems
Features & benefits
- Absolute ratings from 0.5 µm: sub-micron without fragile media
- Rigid: holds its pore geometry under high ΔP and pulsation
- Cleanable and reusable: lower lifetime cost than disposable media
- Weldable into cartridges, baskets, cones and custom elements
- Graded structures for long on-stream time
Specifications
spec.json ↗| Property | Value |
|---|---|
| 2–6 layers of woven mesh, sintered under heat and pressure into one rigid laminate | |
| 0.5 µm – 200 µm absolute, depending on lay-up | |
| Typically 1000 × 1000 / 1200 × 1200 mm; cut, rolled and welded parts on request | |
| Uniform or graded (coarse-to-fine) for higher dirt-holding capacity | |
| Backflushable and regenerable (ultrasonic, chemical, pyrolysis) | |
| High differential pressures; temperatures up to ~600 °C in 316L, higher in special alloys |
Materials & variants
Standard laminates are sintered in 316L; 904L and nickel alloys such as Inconel™, Hastelloy™ and Monel™ cover aggressive chemistry and high temperature. Lay-ups are documented per order, with material certificates and pore-size verification on request.
Frequently asked questions
Sintered mesh or sintered powder: which one do I need?
Mesh laminates offer higher permeability, more strength and better backflushing; powder media reach very fine ratings but clog faster. For most process filtration with cleaning cycles, sintered mesh wins on total cost.
Can sintered elements be repaired or re-rated?
Elements can usually be cleaned and re-welded if the laminate itself is intact. We assess returned elements and advise honestly whether cleaning, repair or replacement is the economical option.
What does an absolute rating of 10 µm actually mean?
Absolute means the largest hard spherical particle that can pass the medium: a 10 µm absolute laminate stops everything larger, verified by pore-size measurement on request. Nominal ratings only promise a percentage. When downstream equipment is expensive, specify absolute and say so in the RFQ.
Can you cut and weld laminate panels to our drawing?
Yes. Standard panels of 1000 × 1000 and 1200 × 1200 mm are cut, rolled and welded in-house into discs, cones, cylinders and complete elements. Weld zones are engineered so the pore structure next to the seam keeps its rating.
How many cleaning cycles does sintered mesh survive?
There is no fixed number: it depends on the contaminant and the cleaning method (backflush, ultrasonic, chemical or pyrolysis). The laminate itself outlasts many cycles as long as differential pressure stays within design limits. We assess used elements and tell you honestly when cleaning stops paying off.
