Why you should have sintered wire mesh installed in your filtration

equipments?
Sintering can be performed on various types of woven wire mesh. The basic reason to sinter a
woven wire mesh is to bond the wires where they intersect hence prevent medium movement. The
woven meshes are normally prone to edge fraying. A square inch of 100 mesh comprises of 200
wire strands intersecting at 10,000 points, several points to join at single time by any other
technique! Although if perfectly sintered, virtually each point will become securely fused. In fact
small discs can be punched from cloth without any fray. It is critical in several applications for
example medical filtration or aircraft hydraulic fluid filtration in which loose wires could cause
catastrophic failure. Additionally the mesh shape is fixed permanently after fusing the wires in their
position. Wires cannot shift even under pressure and hence offer constant aperture size for
applications.

Sintering is also a heat treatment process. If the application condition and cycle are perfectly
controlled, the mesh cloth received is bright and spotless, ductile and metallurgically solution
annealed. Irrespective of annealing, tensile strength is enhanced in many weaves due to the
bonding between the wires. Heat and electrical conductivity are improved. Formability and ductility
are significantly enhanced including the potential to keep shapes and retain pleats.

If bonds are weak or if only a few intersections are bonded or if wires in mesh are readily frayed,
sintering is not done adequately. In many cases sintered term is used on mesh that is hardly
annealed in coil or roll form. If annealing period and temperature are increased, the process may
offer sintering benefits. The results received can be sufficiently good for a given end use however
this process should be called super-annealing or semi-sintering to distinguish it from a real sintering
process. The results may be sufficient for an end use however this process should be named as super
annealing or semi-sintering to distinguish it from a sintering process. The simple roll annealing
processes are more economical as compare to true sintering. Although the product liability costs
resulting when improperly bonded wires fray in major applications will usually justify by using a
costly sintering material in vital applications.

Another major benefit of implementing sintering process is to develop new structures by laminating
multiple layers of wire cloth in laminates or composites of various varieties. A sintered laminate is a
new material, unlike to its component layers and the overall becomes more than the total of its
parts.

The micron-rated sintered wire mesh offers a desired pore size. It is used in various applications
for example filtration, sifting, screening, air intake protection, dust barriers and sparging. Different
structures can be made by using single layer of micron rated wire mesh with several layers of
coarser meshes. The fine mesh can be sintered between the security layers to develop a symmetrical
structure. The applications of this type of mesh include hydraulic valve screens and bi-directional
filtration media.
