Reinforced Structure Pleated Metal Mesh Filter
The strengthen frame metal pleated mesh polymer filter element is formed by ‘a perforated strengthened frame + stainless steel woven mesh + sintered fiber felt + core support frame’. It belongs to a heavy duty melt filter cartridge. Some of the common metal pleated mesh filters are easily deformed, collapsed, cracked, and bulged. By adding an outer punched reinforced frame, the filter element is essentially upgraded from an ‘ordinary folded structure’ to a ‘high-strength compression-resistant depth filter structure’.
Compared with a normal metal mesh pleated polymer filter, the heavy-duty polymer melt filter cartridge has excellent compressive strength, pulse resistance, impact resistance, and deformation resistance, and is especially suitable for high-pressure polymer systems.
Compared with a stainless steel sintered mesh filter cartridge, the metal pleated mesh filter features a large filtration area, high dirt holding capacity, low pressure drop, and high flow rate, making it especially suitable for polymer melt filtration, hydraulic oil filtration, lubricant purification, chemical processing, steam filtration, and high-temperature liquid filtration applications.
Key Advantages of Metal Mesh Pleated Filter Cartridge
Huahang stainless steel woven mesh filter has a multiple times pleated and whole body welded structure. Making it features excellent filtration performance in high-flow, high-viscosity, and heavy dirt working conditions.
Massive Filtration Area
The large filter area is the greatest advantage of Huahang polymer melt pleated mesh filter cartridge. The filtration area can be 3 times, 5 times, or even greater than that of a sintered mesh filter element.
This means higher flow rates, lower pressure drop, and reduced susceptibility to clogging. It is particularly well-suited for polymer melts, high-viscosity media, and continuous production lines.
High Dirt Holding Capacity
Due to the large filtration area, it can accommodate a greater volume of contaminants, and the pressure differential rises more slowly.
So the metal pleated mesh polymer melt filter from Huahang offers a longer service life and is better suited for heavily contaminated operating environments, such as plastics extrusion, film production, and chemical fiber spinning.
High Flow Rate
The pleated structure of the metal-woven mesh filter element is inherently well-suited for high flow rates and low pressure drop.
Many polymer melt systems feature extremely high flow rates and high viscosity liquids; sintered mesh filters are prone to rapid increases in differential pressure and restricted flow rates. Consequently, the pleated mesh structures of the polymer filter offer distinct advantages.
Saving Installation Space
Due to the stainless steel pleated filter cartridge having a high filtration surface area per unit volume, 1 polymer filter’s filtration performance is equivalent to 2-3 sintered mesh filter cartridges.
So what previously required 10 standard sintered mesh filter elements may now require just 3 to 4 pleated filter elements. Consequently, the filter unit is smaller in size, and the overall system is more compact.
Different Structures of Polymer Melt Pleated Filter Element
Huahang Filter supply stainless steel metal woven mesh filters of different filter media structure. The filter is generally made of stainless steel woven mesh, sintered fiber felt, and perforated plate. However, different filtration performance can be achieved by arranging and combining these materials in various ways. Each configuration possesses distinct characteristics and is suitable for different operating conditions.
