This type of sintered wire mesh laminate is made by taking several layers of woven wire mesh and sintering them to a layer of perforated metal. The woven wire mesh layers consist of a filter layer, a protective layer, and possibly a buffer layer between the fine mesh layer and the perforated plate. The perforated plate is then added as the base and the entire structure is sintered together to form a very strong yet tractable plate.
Due to the support of the perforated plate, this type of sintered wire mesh laminate has a high resistance to pressure and high mechanical strength. It is suitable for a variety of applications which require fine filtration, but also the need to protect and preserve the filtration layer. One example of an application is in oil wells, where fine particles need to be filtered under extremely high-pressure conditions.
In general, we use 316L stainless steel wire mesh for the woven wire mesh layers, and 304 stainless steel for the perforated plate. Other special alloys can be incorporated as well.
The woven wire mesh layers can be customized to meet a filtration rating, and the thickness of the perforated plate as well as the type of perforations can be customized as well.
Our standard size is 2’x4′, or 4’x4′, but different size sheets and discs can be made as well. This type of sintered mesh laminate is often used in tube form. These sintered filter tubes can be custom made with a variety of diameters and lengths.
