Sintered Metal Filter Elements: An Overview of the Processing Process

Sintered metal filter elements are favored by various industrial filtration systems because of their superior filtration capacity and durability, and the production and processing of these metal filter elements is crucial to their performance and life, so let’s take a look at it in detail.

A high-quality sintered metal filter element begins with the selection of the appropriate metal powder, usually stainless steel, bronze or other metal alloys. These powders are selected based on their mechanical properties and corrosion resistance, which are essential in metal filter element applications. The first step in the process is to mix these powders and adhesives to enhance the sintering process while ensuring uniformity.

When the metal powder is ready, it undergoes a process of integral compaction, which involves applying high pressure to the powder mixture to form a disk or cylinder shape. It is important to note that the compaction process is crucial because it is related to the density and structural integrity of the metal filter element.

After the end of compaction, it is necessary to start the embryo sintering, high temperature heating, so that the metal particles together, melting produces a porous structure. The sintering temperature and time should be carefully controlled throughout the production process, thus achieving the desired porosity and mechanical strength.

After sintering, some manufacturers may require additional machining or surface treatment of sintered metal filter elements to improve their filter ability and ensure that they meet the specific standards of their industry to withstand harsh working environments.

To sum up, the processing process of sintered metal filter elements is a meticulous process, AHT/ Hartong Wire Mesh Co., Ltd. as a metal filter manufacturer, can provide the required equipment and accessories, can produce and process efficient metal filter components, high quality filtration performance is that they can be competent in various fields from automotive to aerospace filtration work.
