316L stainless steel bronze sintered porous metal filter plate

Also known as DALON sintered filters and frits, these filters have tiny holes that trap very small particles. Discs are often used in laboratories and gas-bubbling applications (sparging). 

They’re made of Bronze / PE or 316L stainless steel for excellent corrosion and abrasion resistance. 

Select Filtering Degree Based on the size of the particles you wish to remove. For example, the particle size of sand is about 80 microns. View more information on reference particle size in microns below:

The manufacturing process of sintered components is certified as ecological, because the material waste is very low, the product is recyclable, and the energy efficiency is good because the material is not molten.

1.RAW MATERIAL / MIXING

Sinter powders can be of pure metal (iron, copper), or alloyed powders (bronze, steel, etc.)mixed with different alloying elements, depending on the composition of the final material (such as graphite, nickel, copper,…), with an organic solid lubricant.

2.TOOLING/COMPACTING

The powder mixture is compacted inside the tooling, which has the negative shape of the final part. The tool is an element of a very high precision, and high durability. The powder is filled into the tool cavity of a mixer by gravity, and  pressure within 200 to 1500 MPa is applied onto it depending on the final density to be achieved. 

3.SINTERING/INSPECTION

Sintering in continuous furnaces, under controlled speed and at an atmosphere with controlled chemical composition by temperatures between 750 and 1300°C depending on the material 

The result of these basic operation is a metallic part with a certain micro-porosity, high dimensional precision, and perfectly functional.

DALON elevated micrometric porosity of filter components is useful for many applications:
