Sintered filter

basic information

A sintered filter is made by filling a mold made of carbon or stainless steel with metal powder of uniform particle size and then sintering it at high temperatures in a reducing atmosphere. It is an assembly of countless metal powders. Utilizing the characteristic porosity of this assembly, it is used as a filter in a wide range of fields. Sintered metal filters possess sufficient filtration performance, heat resistance, durability, and mechanical strength due to our years of experience and technology, and they can be produced in a variety of dimensions and shapes, making them an ideal filter material.

Applications/Examples of results

1. Filtration Substances larger than the specified pore size are stopped, while only those smaller than the pore size can pass through. Additionally, by utilizing surface tension, liquid selective filtration can be achieved. 2. Powder Transport and Drying By sending air from the bottom of the filter, the powder at the top of the filter can be moved or dried. 3. Sound Absorption Used in the exhaust section of high-pressure air, it utilizes the porous characteristics to absorb sound energy and reduce exhaust noise. 4. Explosion Prevention In a flammable atmosphere or during a gas leak, it can absorb energy from sparks and prevent ignition explosions and backfires. 5. Gas Venting It can be used as a vent hole to release gas accumulated in the mold during casting or various forming processes. 6. Foaming Action In brewing and other processes, air or other gases are introduced to create diffusion foaming, promoting chemical reactions.
