Miba AG, Laakirchen, Austria, a producer of a wide range of Powder Metallurgy parts, bearings, friction materials, power electronics components, coatings and components, has highlighted the use of Powder Metallurgy in automotive steering applications. PM steering components, states Miba, offer advantages that include process stability, cost-effective manufacturing process, high precision and complex off-tool geometries.
The company explains that it has actively contributed to safe and comfortable steering for more than fifteen years and operates a zero defects strategy across its six production sites. To-date, several million steering systems with Miba metal powder parts are now on the road.
Whether it’s an internal combustion engine or zero-emission drive, the steering assistance remains indispensable. Sinter technology is an established process in the construction of steering parts.
Process stability, as well as cost efficiency, are said to be the most important measured values of helical toothed belt wheels used in electric steering systems. Other areas of application can be couplings or gears.
Miba explains that high precision and strength is achieved with Powder Metallurgy steering parts thanks to a homogeneous density distribution across all segments of a metal powder part. In addition to the material specifications according to standard, Miba sets tighter tolerance limits for the chemical composition of the powder.
The company also controls the powder transfer during pressing with a multi-stage, rotating tool in order to be able to also produce helical toothed sintered parts. Key parameters are monitored directly at the systems and simulations support the tool design.
