Production process
Punching plate processing
Laser/CNC punching machine punches regular holes in the metal plate to form the supporting skeleton.
Composite mesh preparation
Multiple layers of wire mesh are superimposed (coarse mesh + fine mesh) and fixed by diffusion welding or high temperature sintering.
Roll forming
Roll the perforated sheet and composite mesh into cylindrical shape and weld the joints.
End cap assembly
Weld or cement stainless steel end caps to ensure sealing.
Surface treatment
Cleaning, polishing and passivation to enhance corrosion resistance.
Testing
Air tightness test, precision calibration, pressure burst test.

Frequently Asked Questions
What materials are available for the Sintered Metal Mesh Filter Basket?
The filter basket uses a perforated plate made of stainless steel (304/316L), carbon steel galvanized, or titanium alloy; a composite mesh utilizing multi-layer stainless steel wire mesh (plain, twill, mat weave); and end caps/skeletons made from stainless steel or engineering plastics like PP and PTFE.
What is the operating temperature and pressure limit for these filter baskets?
They can withstand extreme working temperatures ranging from -50°C to 500°C (depending on the material configuration) and support a working pressure strength from 0.5MPa up to 10MPa.
How does the production process ensure the structural integrity of the basket?
The process begins with CNC/laser punching to create a rigid supporting skeleton. Multiple wire mesh layers are then diffusion-welded or sintered at high temperatures. Finally, the roll-formed cylinder is welded with end caps and undergoes strict air tightness and pressure burst testing.
What makes the sintered metal mesh filter basket resistant to clogging?
Its multi-layer filtration design allows for depth filtration, intercepting particles in layers. This optimized pore size distribution ensures high flow rates, reduces fluid resistance, and significantly extends the filter's service life.
Can these filter baskets be cleaned and reused?
Yes. Thanks to their robust sintered metal structure, these baskets can be repeatedly cleaned using backwashing or ultrasonic cleaning methods, offering a high reuse rate and low maintenance costs.
What industries commonly use these filter baskets?
They are widely applied in the petrochemical industry (oil/gas separation), water treatment (desalination), food & pharmaceuticals, energy and environmental protection (dust removal), machinery manufacturing (hydraulic systems), and aerospace (fuel systems).
