The characteristics of woven wire
mesh are improved by bonding the contact points of all the wires together to
form a mesh whose wires are securely fused in place and this process is known
as Sintering. This is obtained using a combination of heat and pressure and the
result is a single layer Sintered Wire Mesh.
5-Layer Sintered Wire Mesh is one of
the most common types of Sintered Wire
Mesh laminates and it is widely used. A single layer of fine woven wire
mesh is placed between two layers of coarser square woven meshes and then added
to two layers of a strong Dutch woven wire mesh and sintered together to form
a strong plate.
The single layer of fine
woven wire mesh acts as the filtration layer and can be customized to meet a
particular filtration rating ranging from 1 micron to 200 microns. These layers
consist of 316L stainless steel wire mesh. Other alloys can also be used
including Inconel, Hastelloy and Monel. Standard size is a 2’x4′ or 4’x4′ sheet
and various size tubes, cones, discs and larger sheets can be fabricated. This Sintered Wire Mesh laminate is used in
numerous industries including food & beverage, pharmaceuticals,
transportation and chemical processing. Various applications of this Sintered Wire Mesh laminate include
pharmaceutical powder processing, fluidized beds, liquid and gas filtration.
PerforatedMetal Sintered Wire Mesh is a
laminate made by taking several layers of woven wire mesh and sintering
them to a layer of perforated metal. The woven wire mesh layers consist of a
filter layer, a protective layer and possibly a buffer layer between the fine
mesh layer and the perforated plate. The perforated plate is then added as the
base and sintering is performed on the entire structure to form a strong and
tractable plate. This Sintered Wire Mesh
laminate has high resistance to pressure and has high mechanical strength due
to the support of the perforated plate. It is ideal for various applications
that require filtration and also require the protection and preservation of the
filtration layer. One such application is oil wells where fine particles need
to be filtered under extremely high pressure conditions. Various alloys can be
used including the 316L stainless steel wire mesh which is commonly used for
the woven wire mesh layers and the 304 stainless steel which is commonly used
for the perforated plate.
The customization of the woven wire mesh layers can
be done to meet the filtration rating and the customization of the thickness of
the perforated plate and type of perforations can also be done. Standard size
is 2’x4′, or 4’x4′ and various size discs and sheets can be manufactured. This Sintered Mesh Laminate is commonly used
in tube form. The customization of these sintered filter tubes is done in a
variety of diameters and lengths.
Another type of Sintered Wire Mesh laminate is Plain
Weave Sintered Square Woven Wire Mesh that is manufactured by sintering
multiple layers of plain weave square woven wire mesh together. This Sintered Wire Mesh laminate has
excellent permeability characteristics and low resistance to flow due to the
large open area percentages of the square woven wire mesh layers.
