Sintered metal filter cartridge, is made of stainless steel woven wire mesh, or stainless steel fiber felt. It is constructed by using multi-layered wire mesh overlapped and then sintered together in vacuum furnace, rolled into a cylinder shape with two ends welded together. Rolling seam welding process is added for roundness and flatness of entire structure. Its interlaced mesh forms a rigid structure which overcomes the disadvantages of ordinary wire mesh, such as low strength, unstable hole shapes, also beats sintered powder filter, ceramic filters, etc. Above all, this stainless steel filter cartridge wins great favor with prominent features like high temperature resistance, smooth wire pores, good permeability, high dirt holding capacity, in many industries such as food, environmental protection, chemical, aerospace.

Sintered mesh laminate belongs to high strength porous material. It is made of stainless steel or other alloys. Single layer or multiple layers of woven wire meshes are permanently bonded together by an unique diffusion-bonded technique. Compared with traditional wire mesh, sintered mesh laminate provides more additional benefits such as stability and mechanical strength. Therefore, it is widely constructed as a filter medium in many industries.

Sintered mesh with perforated metal, also named perforated metal sintered wire mesh, is a kind of compound sintered mesh which fits precise filtration and the need to protect the filtration layer. It is produced by combing several layers of stainless steel woven wire meshes and then sintering them to one piece of perforated metal. The support of a perforated metal sheet makes the sintered mesh extremely resistant to pressure and offers high compressive and mechanical strength. The perforated metal laminate varies in thickness and the opening of the hole size, the woven wire mesh can be one or more layers, which all fit the need of real application. Perforated metal sintered wire mesh can also be processed into different shapes, like chip, conical, cylinders, disc and tube. Owing to its outstanding permeability and great strength, it plays an important role in diverse filtration applications such as gas and liquid separation, recycle of solid particles, etc.

Five-layer sintered mesh is a standard combination of five layers wire meshes with different openings and diameters through sintering (diffusion-bonding) in vacuum, which improves the characteristics of stainless steel woven wire mesh. By bonding the contact points of different wire meshes together, five-layer sintered mesh has become an integrated porous material with enhanced mechanical strength, high permeability and better structural integrity, because the sintering process remains the good filtration rating of the finest mesh layer, also the mechanical strength of the coarser support layers. Besides all of that, heat and pressure are combined to create molecular diffusion-welds at every intersection of the wire mesh where the wires cross over and under one-another, which in turn enhances the temperature and pressure resistance of the sintered mesh. For its distinct features, five-layer sintered mesh is widely used for diffusing, breather vents, filters in many areas such as gas distribution, polyester filtration, water treatment, etc.

Sintered metal filter disc, is an ideal filter element for accurate filtration. It is made from sintered wire mesh through laser-cutting. Sintering is a process which produces fusion bonds at all contact points of the woven wire mesh in the vacuum environment with high temperature. Sintering maintains the uniformity of the original weave and fixes the hole size, shape and micron rating of the mesh. The sintered wire mesh can be monolayer or multi-layered, whichever is full of high strength and rigidity. For various purposes, sintered metal filter discs can be processed into different shapes, like round, toroidal, square, oval or fan-shaped. According to customers' demand, sintered metal filter discs can also be added outer rings. Sintered mesh filter disc is widely used in filtration process in many industries, it works as gas-liquid separation, oil and fuel filtration.

Pleated sintered mesh filter is made of stainless steel wire mesh, or sintered metal fiber felt, which is sintered at each wire contact point to produce a strong surface-sieving porous filter cylinder. Moreover, the filter element is pleated design that further provides large filter area, good dirt holding capacity. Double open-ended or single open-ended is available as per customers' need, threaded end is often equipped with gasket, like o-ring, to reduce the friction of the corrugated filter. Unlike unsintered mesh, pleated sintered mesh filter enables the use of finer wires to produce more pores per unit area for higher contaminant loading capacity. On the other hand, pleated sintered filter cartridge is more preferred to replace the PP filter cartridge with its back washing and reusability advantage, in applications of corrosive liquid filtration, oxidizing liquid filtration, liquid and gas filtration, etc.
