Sintering is a forming process in which metal powders are compressed in a die under controlled pressure. In a subsequent sintering step, the pressed parts are heated in a protective gas atmosphere, causing the particles to fuse into a high-strength component.
This process is characterized by exceptional design freedom in two-dimensional geometries and high dimensional accuracy. Tolerances in the IT 7 to IT 8 range can be achieved, making sintered components ideal for use in gears, hydraulic parts, and other precision applications.
The base materials are typically iron- or copper-based, and depending on the application, alloyed with elements such as chromium, nickel, or others. Subsequent impregnation with oil or other lubricants results in excellent sliding and anti-friction properties.
Sintering enables the efficient production of precise components in just a few steps, with minimal material waste. Many parts can be used immediately after sintering or further processed without limitations.
