What is a Sintered Wire Mesh?
A sintered wire mesh is a filtering material constructed through pressing and sintering single or several layers of woven wire mesh panels.
The process forms strong, permanent bonds through heat and pressure, giving it superior and comprehensive filtration properties compared to standard woven wire mesh filter.
A sintered wire mesh can have between 2 and 7 layers or even more dependent on the customer’s needs and specifications.
Initially, you uniformly roller flattened a single layer of wire mesh to create a wire cross to ensure efficient contact.
If you want to create a multilayered mesh, then proceed and pile the components appropriately, ensuring that you laminate the fine filtering mesh with coarser protective layers.
Using a unique fixture, laminate the single or multiple mesh layers through subjecting it to high temperature and mechanical pressure.
Press in chambers filled with proprietary inset gas and raise the temperature to reach the sintering (diffusion bonding) levels.
Cool the sintered wire mesh under controlled conditions to achieve the desired level of rigidity.
After that, you can follow and work the material as expected: weld, cut, pleat, roll into diverse shapes, etc.
What is the Importance of Sintering a Wire Mesh?
Pressing and sintering metal wire mesh creates a filtration material with superior filtration properties compared to standard woven wire mesh.
Sintering creates a secure and stable wire mesh that is suitable for use under high-pressure conditions.
You can use a sintered wire mesh to construct diverse kinds of filter elements such as cartridges, cylinders, discs, and candles because they have excellent mechanical strength, very stable, and durable.
What is the Difference Between Sheet Sintering and Coil Sintering?
Both sheet sintering and coil sintering are done to permanently bond the wire mesh intersections through heat, pressure, time, and atmosphere.
However, you can construct either single of the multilayered sintered sheet while you can only build a single layer of the sintered coil.
Whereas sheet sinters are ideal for filtration in high-pressure applications, coil sinters are suitable for applications that cannot tolerate loose wires and deep drawing.

What Factors should you Consider when Constructing a Filter Element using a Sintered Wire Mesh?
The design specifications of your filter element must meet the desired level filtration and withstand your system’s operating conditions.
The following are some of the basic parameters you should consider while designing your sintered wire mesh filter elements.
· Pore Sizing
Your filter’s pore size rating dictates the size of particles your filter will be able to retain.
A filter element rated 5 microns’ absolute’ will retain all particles with a diameter of 5 microns and below.
In contrast, when the same filter is rated ‘nominal,’ then your filter will allow a high percentage bypass of the particles measuring 5 microns.
· Pressure Drop
Pressure drop is the loss of pressure on the filter outlet due to slowing down the process fluid as it goes through the filter.
Determine the allowance of your system pressure drop during the filter designing so as not to slow down your production process.
· Operating Temperature
You should determine the minimum and maximum allowable temperatures that your process application operates on.
It ensures that the metal alloys you choose can tolerate the temperature extremes on both ends to avoid element disintegration.
· Strength
Though all sintered woven wire mesh filers possess excellent tensile and mechanical strength, you still need to determine your system requirements.
Fabricating sintered wire mesh filter elements that meet the system specifications goes a long way to ensure your filter elements’ effectiveness and durability.
· Others
In addition to the above considerations, you also need to have a more profound mastery of your process application to ensure that you fabricate the most suitable elements.
Accompanying your order alongside the following information will deliver you a product that is accustomed to your system’s unique needs.
