The production process of stainless steel sintered filter element

Stainless steel sintering mesh filter element is referred to as stainless steel sintering filter element. The filter element is made of a standard five-layer sintering net by superposition and vacuum sintering.

The sintered filter element is made of stainless steel sinter mesh. The sintered mesh is divided into five parts: protection layer, filter layer, dispersion layer, framework layer, and framework layer.
This kind of filter material not only has a uniform and stable filtration precision but also has high strength and rigidity. It is an ideal filter material for occasions with high compressive strength and uniform filtration precision.

The main difference between stainless steel sintered mesh filter elements and other filter elements is that a large number of high-precision welding processes are adopted. The stainless steel mesh sintered filter element is made of the sintered mesh by cutting and high precision welding.
The most important point of the sintering filter is the use of a large number of high-precision welding processes. The sintering filter is welded after being rolled around. The roundness of the welding place should be ensured. The welding seam should be corrected after being welded flat, which can make the overall appearance more beautiful.

The selection of raw materials, precision control, and later welding process are three very important factors of stainless steel sintered mesh filter element. The products on the market are fishy-eyed, inferior materials, low filling, high filtering precision, and rough processing technology make some products offer extremely low prices. Customers need to polish their eyes to avoid the loss of production accidents.

The main difference between stainless steel sintered filter element and other filter elements is that a large number of high-precision welding processes are adopted. The stainless steel sintered metal mesh is welded after rounding treatment. The roundness of welding should be ensured, and the welding seam should be leveled after welding, so as to make the whole look beautiful and prepare for the whole welding in the next step.

Then the sintering metal mesh is welded on the end covers of both ends by stainless steel welding wire. The sintering net can not be burned out in the welding process, so as to prevent local burning and breakdown, resulting in the filter element can not play a filtering role, so the welding environment must be protected by argon gas in the welding process.
All the above welding processes must have welding tooling and special welding equipment, and the welding technical requirements for workers are relatively strict. In case of air leakage in the pressure range of the bubbling test after welding, all filter elements will be scrapped.

The production process of stainless steel sintered filter element is complex and the material is expensive, but it has a good effect and can be used repeatedly. Therefore, the price is not high in the long run. In addition, if we choose the product specifications that we often produce, we often make the filter element of this specification. We have both tooling and welding equipment, and the workers are skilled. The price will be low and the construction period will be short Can shorten, if it is a non-standard model, you need to open a new mold, and make tooling and other auxiliary equipment, so the cost will be higher.
