Sintered Metal Filter

8 Main Features of Sintered Metal Filters  

HENGKO metal sintered filter products mainly consist of sintered stainless steel filters, sintered bronze filters, 

sintered mesh filters, sintered titanium filters, metal powder filters, sintered metal filter discs, and 

sintered stainless steel tubes. They all have reliable performance for anti-corrosion, high temperature,

and high precision application. 

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. Here are eight features of sintered metal filters: 

1. High strength: Sintered metal filters are made from metal powders, which gives them high strength

     and durability. 

2. High-temperature resistance: Sintered metal filters can withstand high temperatures, making them

    suitable for high-temperature environments. 

3. Corrosion resistance: Sintered metal filters are resistant to corrosion and can be used in corrosive

    environments. 

4. Chemical resistance: Sintered metal filters resist most chemicals, making them suitable for chemical

    processing applications. 

5. High filtration efficiency: Sintered metal filters have a very fine pore structure, which allows them to

    filter out very small particles effectively.

6. High dirt-holding capacity: Sintered metal filters have a high dirt-holding capacity, meaning they can

     filter large volumes of fluids before they need to be replaced.

7. Easy to clean: Sintered metal filters can be easily cleaned and reused, making them cost-effective

    in the long run. 

8. Versatility: Sintered metal filters can be made in various shapes and sizes to meet the specific needs

    of different applications. 

For porous metal filter, stainless steel is a perfect filtration choice in chemical processing, petroleum refining,

power generation, pharmaceutical production, etc.

All sintered filter elements from HENGKO need strict quality testing before shipping out, including filtration

efficiency and visual inspection. Compared to other metal filter suppliers, HENGKO's sintered metal filter has

higher particle removal efficiency, corrosion resistance, less pressure drop, easier cleaning, and backwash advantages.

HENGKO has the know-how of mechanical stability in cold isostatic pressing and sintering processes. Whether liquid or

gas filtration, HENGKO always provides trusted and long-lasting solutions. Fabricating Sintered Metal Filters are simple and easy.

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.

Sintered Metal Filters: A Complete FAQ Guide

A: Features of Sintered Metal Filter

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 proce 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.

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
3. Flow test (gas and liquid)
4. Salt spray test (anti-rust test)
5. Dimensional appearance measurement

     5. Flame Arrestor     6. Gas Filtration 

     7. Food and Beverage  

7. Can l Use Sintered Metal Filters with Multiple Types of Oils? 

      Yes, but need to customize special pore size as the oil , also the flow control requirement, so

       you can welcome to contact us to let us know your details.  

8. Can a Sintered Metal Filter Continue to Work Even when the Conditions are Freezing?

     Yes, for sintered metal finter, such as 316L sintered stainless steel filter can work under

-70 ℃~ +600℃ , so  for most of sintered filter can work under freezong. but need to ensure

Liquid and gas can flow under the freezing condition. 

9. What Kind of Chemicals Can filter by Sintered Metal Filters and Without Harming the Filter Body ?
