Plain/twill-woven wire mesh (square mesh) has been widely used to form filters and sieves. Weaving method is selected to meet such factors as the open area-to-wire size ratio and the application.
We have acquired high reputation particularly for our expertise in manufacturing fine mesh with aperture of 150μ and smaller.
The main difference between an ordinary wire mesh (mesh with square apertures) and a wire mesh used as a filter is that the weft wires of the filter mesh are arranged in contact with each other so that no aperture can be seen from above (the so-called zero-open weave). Thus, the percentage of open area in the filter mesh cannot be measured precisely. Aperture size of the filter mesh can be estimated from the relationship between the flow rate of liquid and the pressure drop across it, or from the fine particle capturing capability.
Aperture size of the filter wire mesh is determined by measuring the absolute value captured particle size (usually in micrometers) with the maximum bubble pressure method (JIS B8356).

Filtering size is estimated by measuring the bubble point value and the size of the contaminant particle passing through the wire mesh.
[Nominal filtering size: At least 95% of foreign matter larger than this value is removed.
Absolute filtering size: 100% of foreign matter larger than this value is removed.]
Several sheets of stainless steel wire mesh are placed one on another and are sintered under pressure, thus forming a filter with higher strength and higher sintering accuracy. We will produce an optimum filter medium by adjusting the composition (combination) of the wire mesh to meet the application.
Filter medium for polymers will be provided with a high-strength support layer.
We can also manufacture pleated filter medium having an increased filtering area, and filter media integrated with reinforcing support layer for extrusion machines, so as to provide the best filter medium and elements for the application and the intended process.

Sintered nonwoven fabric made of metal fibers measuring on the order of micrometers. In contrast to the stacked sintered wire mesh that performs filtering only on the surface layer, this fabric performs filtering both in the internal structure and on the surface layer. With the internal filtering structure having an extremely high void ratio, it has excellent foreign matter capturing effect. This is the long-awaited filter medium, capable of achieving high-speed filtering with low power consumption.

Steel sheet punched out with a press die to form a multitude of holes; it is also called punchout metal mesh.
Standard specifications are: hole diameter 0.35 to 50mm; pitch 1 to 45mm; percentage of open area 10 to 60%. The hole shape may be round, cross, square, oval, etc. The holes are arranged in 60°staggered or parallel arrays.
Punching metal is used as a cover that passes air or sound, in sound insulation/heat insulation panel, interior/exterior material of buildings, strainers, granulation/crushing machine, sifting of grains, gravel or pharmaceutical materials, etc.
Punching metal cannot be used in filtration of fine particles due to limitations on the size of holes that can be formed, but it is used to reinforce the main filter.

The wire mesh demister is used as a filler that is woven to separate (by fractionation, rectification) foreign matter from liquid or gas; it is also used as a shielding material or core material.
