Seat Adjuster Outer Ring
Benefit: Increased Component Complexity
Main Forming Process: Conventional Processing
End Use Sector: Automotive
Material: Ferrous

Finishing: No further finishing required

Requirements

Due to different patents, TIER 1 suppliers have to find new geometries for their seat adjuster systems. This leads to ever more new designs. At the same time new generations need to be improved, eg. To become lighter, more compact, display higher stiffness, and be quieter in operation. Thus the “Outer Ring” is a complex shaped high-strength part, however the biggest challenge was the tolerance of the inner radii being only 50μm.

Benefits

Sintering had minimum distortion compared to other heat-treatment methods and was instrumental in achieving the required accuracy. The processed material withstands the high-hertz’s pressure applied by three needle bearing pins via to the internal part. Requirements for Transport torque is about 20Nm, and misuse torque approx. 100Nm, without significant deformation both of which were achieved using PM.
