Sintered metal filters
Sintering technology is also ideal for the development and manufacture of filters. The process is the same as with traditionally sintered components, but the variation of pore size and carefully controlled pore distribution are utilised to produce components with a filtering function.
Sintered components’ special property in terms of porosity is utilised to produce filters that do not suffer from the same shortcomings as conventional solutions. The sintering process holds the material together so that stainless steel sintered filters are both stronger and better than conventional filters.
Sintered filters have fine tolerances and considerable geometrical possibilities. For instance, it is often possible to reduce the number of subcomponents and processes in the final filter solution, since a number of the subcomponents can be replaced by a single filter that is compressed in a single process. This avoids further time-consuming machining. The method chosen depends on the proposed application of the filter.
The exploitation of the porosity enables the filters to be used for applications such as gas and liquid filtration, flow control of gases and liquids, as well as ventilationl:
