Production Introduction
Porous Metal Filters are made by irregularly shaped stainless Steel powder, Generally AISI 316L.
During the production of stainless steel sintered filters, the powder is compressed into a mold to create a solid, brittle component. The pore size can be determined by the power that is chosen and the pressing force that is applied.The filters ultimate properties are influenced by the shape, size and distribution of the powder.
