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. 

Applications -- Noise Reducer Sinter Porous Metal Bronze Powder Filter

- Filtration of fluids. Porosity is able to retain the solid particles contained in a liquid or gaseous fluid, and also to separate liquid and solid phases. The application sectors are: automotive, marine, aeronautical, rail, industrial machinery, household appliances, heating, water depuration, food industry, chemical and nuclear industry, packaging manufacturing, tobacco pipes and electronic cigarettes, etc.

- Pressure drop. Porosity decreases the pressure of the fluid that circulates through it. Different applications are: pressure control in pneumatic and hydraulic circuits (compensators, drainers, regulators), noise absorption of gas piping (Silencers), pneumatic cylinders, sensors and manometers protection, gearboxes, etc.

- Flow control. The isotropic and homogeneous porosity allows that a fluid that circulates through it have a constant flow at the exit of the porous part. Typical applications are heat exchangers, medical gases, scuba diving, industrial gases, etc. 

- Aeration. The air circulation through porosity results in a constant and controlled air flow at the exit of the porous component. The use sectors are: liquids repassing in food industry (liqueurs, wines, and gas beverages), ionization, gas burners, aquaria, clinical analysis, etc. 

- Fluidization. The air circulation through the porous component has as result that the exit flow is distributed with the same pressure in all points, allowing then the controlled handling of powdered products. This property is used for: transporting cement, flour, alumina, ashes, toner powder, etc. 

- Anti-moisture. Porosity is able to retain and condense the moisture contained in a gas that circles through it. Typical applications are: drying in general, electronic equipment's protection, etc. 

- Flame protection. Presence of a porous component before a flame avoids accidents in case of flame return. Typical applications are: gas burners, heaters, welding facilities, etc.

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.
