Successful Case of Customized SS316L Sintered Powder Filter Cartridge for French Industrial Customer

A French environmental protection equipment manufacturer purchased 300 pieces of customized sintered powder filter cartridges for a high-end water treatment system, requiring square filter sheets (250x250x3mm) made of SS316L to achieve 20 micron filtration precision. Through powder particle size control, three-dimensional sintering molding technology and precision testing system, we have completed the EU standard certification and mass production delivery. This case verifies the technological breakthrough of domestic sintered cartridge in harsh industrial scenarios.

1: Powder metallurgy technology realizes high-precision fluid control
● SS316L powder of -400 mesh is selected to ensure 20 micron porosity ≤5% through particle size screening.
● Vacuum gradient sintering process is adopted to maintain a three-dimensional through-pore structure at 1280℃.
● Third-party testing shows filtration efficiency of 99.92% (ISO2941 standard)

2: Customized production capacity to meet special form requirements
● Development of square molds to compensate for sintering shrinkage, finished product size tolerance control at ±0.15mm
● Unique edge chamfering design to avoid the risk of seal failure during filter assembly
● Flexible production capacity of 50,000 pieces of shaped filter elements per month.
