Sintered Metal Filter

Why Choose Sintered Metal Filters for Your Filtration Projects: 

Sintered metal filters are made from metal powders that are pressed and sintered (fused) to form a porous,

solid structure. These filters are known for their high strength, durability, and ability to filter out very small particles.

Application of Sintered Filter Products 

Sintered filters are used in a wide range of industries, including chemical processing, petroleum refining, power generation, and pharmaceutical production. They are ideal for use in applications where a high level of filtration efficiency is required, and where the filter must be able to withstand high temperatures, pressures, and corrosive environments. Some of the most common applications of sintered filter products include:

Liquid Filtration

Sintered metal filters are commonly used for liquid filtration in a variety of industries. They are particularly useful in applications where the liquid being filtered is viscous or contains a high level of solids. Sintered filters can remove particles as small as 1 micron, making them ideal for use in applications where a high level of filtration efficiency is required.

Fluidizing

Sintered metal filters can also be used for fluidizing applications, where they help to evenly distribute gas or liquid through a bed of solid particles. This is particularly useful in applications such as catalysis, where it is important to ensure that all reactants are evenly distributed.

Sparging

Sintered metal filters can also be used for sparging applications, where they help to introduce gas into a liquid. This is particularly useful in applications such as fermentation, where it is important to ensure that the liquid being fermented is well-aerated.

Diffusion

Sintered metal filters can also be used for diffusion applications, where they help to evenly distribute gas or liquid through a membrane. This is particularly useful in applications such as fuel cells, where it is important to ensure that the reactants are evenly distributed across the membrane.

Flame Arrestor

Sintered metal filters can also be used as flame arrestors, where they help to prevent the spread of flames or explosions. This is particularly useful in applications such as refineries or chemical plants, where flammable materials are present.

Gas Filtration

Sintered metal filters are also used for gas filtration in a wide range of industrial applications. They are particularly useful in applications where the gas being filtered contains a high level of moisture or other contaminants. Sintered filters can remove particles as small as 0.1 micron, making them ideal for use in applications where a high level of filtration efficiency is required.

Food and Beverage

Sintered metal filters are also used in a variety of food and beverage applications, including the filtration of beer, wine, and other beverages. They are particularly useful in applications where a high level of filtration efficiency is required, and where the filter must be able to withstand high temperatures and corrosive environments.

4-Tips When Choose & OEM Sintered Metal Filter You Should Care 

There are several ways to customize sintered metal filters to meet specific application requirements.

Some common methods include:

1. Selecting the appropriate metal:

     Different metals have different properties that can affect the performance of the

     sintered metal filter. For example, stainless steel is corrosion-resistant and has a high melting point, while

     aluminum is lightweight and has good electrical conductivity.

2. Specifying the pore size and shape: 

     Sintered metal filters can be designed with pores of different sizes and

     shapes to suit different filtration needs. For example, a filter with smaller pores will be more effective at removing

      smaller particles, while a filter with larger pores may be more suitable for high flow rates.

3. Varying the filter media thickness:

     The thickness of the filter media can also be adjusted to suit specific

     application requirements. Thicker media can provide greater filtration efficiency but may also result in higher

      pressure drop and reduced flow rates.

4. Adjusting the temperature and pressure conditions:

    Sintered metal filters can be designed to withstand specific

    temperature and pressure conditions, depending on the application. It is important to consider these factors when

    selecting a filter to ensure that it can withstand the system's operating conditions.

To customize a sintered metal filter to meet your specific requirements, consulting with an experienced engineer

or a technical expert in the field may be helpful. They can guide the appropriate design and material selection based

on the specific application requirements.

FAQ for Sintered Metal Filters

1. What is a Sintered Metal Filter ? 

     A short definition of sintered metal filter: It is a metal filter that uses metal powder particles of the same particle size

to be shaped by a stamping, high-temperature sintering is the process of metallurgy using powder-sized

bodies of different metals and alloys after stamping.

Metallurgy occurs by diffusion at temperatures below the melting point of high-temperature furnaces. The metals and alloys

commonly used today include aluminum, copper, nickel, bronze, stainless steel, and titanium.

There are different processes you can use to form the powder. They include grinding, automation, and chemical decomposition. 

More Details about What is Sintered Metal filter, please go and check our this article. 

2. Why Use Stainless Steel Metal to Make Filter? 

      To Choose Stainless Steel Metal as the main materials, just because have many benefits for stainless steel

   1. Not easy to rust 

   2. The sintering temperature does not need to be too high

   3. Pores are easy to control during sintering

   4. Sintered molding is more durable and not easy to deform

   5. Easy to clean

3. How is a Sintered Metal Filter Made ? 

      For the manufacturing process of Sintered metal filter, main have 3-steps as follow:

      A:  First step is to get the power metal.

          The metal powder, You can obtain metal powders by grinding, automation, or chemical decomposition. You can combine one metal

powder with another metal to form an alloy during the fabrication process, or you can use only one powder. The advantage of sintering is that

it does not change the physical properties of the metal material. The process is so simple that the metal elements are not altered.

       B:  Stamping

       The second step is to pour the metal powder into a pre-prepared mold in which you can shape the filter. The filter assembly is formed at room

temperature and under stamping. The amount of pressure applied depends on the metal you are using, as different metals have different elasticity.

After a high-pressure impact, the metal powder is compacted in the mold to form a solid filter.  After the high-pressure impact procedure, you can

place the prepared metal filter in a high-temperature furnace. 

        C:  High-temperature sintering

        In the sintering process, the metal particles are fused to form a single unit without reaching the melting point. This monolith is as strong,

rigid, and porous a filter as the metal.

        You can control the porosity of the filter by the process according to the flow level of the air or liquid to be filtered. 

4. What is the Process of Sintering? 

    One important step is Sintering,  so what is the process of sintering and to be metal filters ?

     You can check as follow chart to understand clear. 

5. What Are the Main Specifications of Sintered Metal Filter? 

     After the process of stamping and high temperature sintering, we can get the sintered metal filters, then in

order to know the quality of the sintered filters, normally, we will test some data of the filters, if the data reach

the requirements as the clients asked, then we can release to arrange to shipping out.  

1. Porosity
2. Compression test
