Stame, a company established in 1977, realizes sintered mechanical parts, obtained by metallic powder compaction followed by heat treatment. This technology begins with powder mixing of the required material: iron, steel, copper, aluminum and alloys, magnetic materials, etc. Then, the powder mix is pressed within dies in order to impart the component the final geometry. Subsequently, the mechanical part made of pressed powder undergoes the sintering treatment. This is a heat treatment in an inert atmosphere between 1120 °C and 1350 °C for a variable amount of time, followed by slow or fast cooling in forced atmosphere (sinter-hardening). Sintering allows the pressed powder granules to create an interatomic bond so that the component can develop the required mechanical properties. After sintering, parts can be finished or may require deburring processes, machining operations by chip removal, heat treatments or different surface treatments.
