Production Process of Sintered Metal Powder Filter Cartridge
Raw material preparation: Select qualified metal powder (particle size, chemical composition), and add binders or additives if necessary.
Powder batching and screening: Screen and mix according to the formula to ensure the particle size distribution and uniformity of the powder.
Molding: Compression molding or injection molding; Sometimes isostatic pressing is used to improve density uniformity.
Pre burning/degreasing: (if containing organic binders): Low temperature heating to remove organic matter and prevent sintering defects.
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.
Heat treatment/tempering: (if necessary): Improve mechanical properties or eliminate stress.
Mechanical processing: Finished product processing: cutting, turning end faces, punching, welding flanges or joints, flanging, etc.
Surface treatment & cleaning: such as acid pickling passivation, sandblasting or polishing, ultrasonic or chemical cleaning to remove residual impurities.
Inspection and testing: size, porosity, gas permeability, filtration efficiency, pressure resistance, metallographic examination, etc.
Packaging & shipping: Protection, cleanliness level labeling, and accompanying inspection reports.
