The manufacturing process of stainless steel filter cartridges is a complex process involving multiple steps to ensure that the filter cartridges have good filtration performance, durability, and reliability. The following is the general process for manufacturing stainless steel filter cartridges:
1. Raw material preparation
Choose suitable stainless steel materials, usually 304 or 316L stainless steel, which have good corrosion resistance and high temperature resistance.
Prepare basic materials such as stainless steel fibers, stainless steel woven mesh, or stainless steel wire mesh.
2. Filter material manufacturing
Stainless steel fiber sintered felt: Stainless steel fibers are made into porous deep filter material through high-temperature sintering process. This type of filter material can be made into a multi-layer structure with pore sizes ranging from coarse to fine, possessing high porosity and high pollutant holding capacity.
Stainless steel woven mesh: Using stainless steel wires of different diameters to weave into a mesh structure, it has good strength and stability.
3. Forming
The main body of the filter element is formed by laminating and pressing the filter material.
Process the filter material into a specific shape through wave bending technology to increase the filtering area and improve the filtering effect.
4. Welding
Using welding techniques such as argon arc welding to connect the various components of the filter element, ensuring sealing and strength.
For stainless steel sintered filter cartridges, multi-layer stainless steel filter screens are usually pressed through special layers and then welded and fixed.
5. Sintering
For stainless steel sintered filter cartridges, multiple layers of metal woven wire mesh need to be laminated and pressed, and then sintered in a vacuum sintering furnace to form a sturdy structure.
During the sintering process, temperature and time need to be controlled to ensure the porosity and strength of the filter element.
6. Assembly
Assemble the filter body with other components (such as end caps) to form a complete filter assembly.
