Production Process of Sintered Metal Powder Filter Cartridge
1.Raw material preparation: Select qualified metal powder (particle size, chemical composition), and add binders or additives if necessary.
2.Powder batching and screening: Screen and mix according to the formula to ensure the particle size distribution and uniformity of the powder.
3.Molding: compression molding or injection molding; Sometimes isostatic pressing is used to improve density uniformity.
4.Pre burning/degreasing (if containing organic binders): Low temperature heating to remove organic matter and prevent sintering defects.
5.Sintering (high temperature): Heat up according to the process curve in a protective atmosphere or vacuum to the sintering temperature and keep it warm to form a dense/porous metal skeleton.
6.Heat treatment/tempering (if necessary): Improve mechanical properties or eliminate stress.
7.Mechanical processing and finished product processing: cutting, turning end faces, punching, welding flanges or joints, flanging, etc.
8.Surface treatment and cleaning: such as acid pickling passivation, sandblasting or polishing, ultrasonic or chemical cleaning to remove residual impurities.
9.Inspection and testing: size, porosity, gas permeability, filtration efficiency, pressure resistance, metallographic examination, etc.
10.Packaging and shipping: Protection, cleanliness level labeling, and accompanying inspection reports.
Advantages of Sintered Metal Powder Filter Cartridge

Selection Suggestions and Maintenance Points
- Select the rated pore size based on the filtered medium (gas/liquid), particle size distribution, and required retention efficiency.
- Considering the working temperature and corrosiveness, choose suitable materials (such as 316L or more corrosion-resistant nickel based alloys).
- If frequent cleaning is required, choose a structure that is easy to disassemble or can be backwashed in situ.
- The maximum allowable pressure difference should have a safety margin to avoid exceeding the design pressure difference when the filter is clogged.
- Cleaning methods: backwashing (liquid/gas), ultrasonic cleaning, acid washing/alkali washing (note material compatibility), high-temperature burning to remove organic matter.
- Regularly check the filtration efficiency and pressure drop curve, and clean or replace if there is a significant increase in pressure drop or decrease in efficiency.
If needed, I can:
- Based on your working conditions (medium, temperature, pressure, target particle size, flow rate, etc.), help recommend specific model parameters;
- Provide standardized technical parameter tables (which can be directly used for quotation or technical specifications);
- Explain the specific operational steps and precautions for common cleaning and regeneration processes.
