Sintered Mesh
Sintered woven wire mesh and non woven sintered web can be in used for several ( fine or deep or sub micron) filtration applications in for example the petrochemical and chemical industry, water conditioning and pharmaceutics.
Sintered woven wire mesh consist of multi-layers of woven wire mesh laminated together by use of ' sintering '.
This creates an enormous class of new materials with a very wide variety of mechanical properties. By combining multiple layers of different mesh weavings, it is possible to design materials with specific target thickness, permeability, pore size, and mechanical strength. Some layers are used for high precision filtration, others for protecting and reinforcing.

Examples of sintered mesh |

Sintered wire mesh is produced by a series of technical processes. Precision woven wire mesh is uniformly calendered (roller flattened) to ensure good contact at the wire cross over points. One or more layers of this calendered mesh are then laminated under mechanical pressure in special fixtures inside a high temperature furnace. This furnace is filled with a proprietary inert gas atmosphere and the temperature is raised to a point where sintering (diffusion bonding) occurs. After controlled cooling, the mesh has now become rigid by the bonding of the individual wires to each other and of each layer to the adjacent layer. Its comprehensive property is superior to sintered metal powder/granulate and porcelain.

As compared with sintered woven wire mesh, sintered filter media based on metal granulate are by the very nature of their granular construction, prone to fracture or disintegrate when subjected to the stresses of shock or to a combination of high temperature and vibration.
The final product has an excellent strength. No inner support is required for making filter elements, cleaning is easy and long lifespans are possible. Common applied materials are stainless steel types 304L and 316L. Exotic metals or alloys are possible. Filtration ranges from approx. 0,5 to 60 microns. The maximum size of a sintered woven wire mesh panel amount to approx. 500 x 1000 mm. Larger dimensions can be obtained by precision welding of panels.

(Sintered) woven wire mesh can be combinated with a non woven sintered web. Combinations of these materials will result in filtration area´s from about 0.5 microns.
Averinox supplies filters/ separators or fitersegments as your specification, based on among others on sintered (woven) wire mesh, see Filter Eelements.
