Manufacturing Process of Sintered Filter
The manufacturing of a sintered filters follows a precise powder metallurgy process, and the resulting product achieves impressive filtration accuracy—typically ranging from 0.1 µm to 100 µm, depending on materials and sintering conditions .
1.Metal powder selection
Choose appropriate powders (stainless steel, bronze, titanium, or nickel alloys) based on required filtration grade and corrosion resistance.
2.Compaction
Compress the metal powder into the desired shape using high-pressure molding to form a compacted preform.
3.Sintering
Heat the compacted form to just below the metal’s melting point, creating a strong, porous structure with controlled pore distribution.
4.Post-treatment
Final adjustments such as machining, cleaning, or bonding are made to meet design specifications and ensure surface finish and tolerance.
Structure and Properties of Sintered Filter

Sintered filters must have good performance to ensure stable quality in demanding applications.
1.Uniform pore distribution
