COMFORT & SAFETY

Components for automotive comfort and safety systems

Comfort and safety are decisive purchase factors – and tolerate no compromise in quality. Schunk Sinter Metals manufactures interior and safety components with two complementary manufacturing processes: axial pressing for high-volume molded parts and metal injection molding (MIM) for complex precision components.

Two manufacturing processes – one point of contact

Axial pressing is the proven standard process for simple to medium component geometries in high volumes. Press forces from 30 to 8,000 kN, outstanding process stability, and economical large-scale production make it the process of choice for gears, bearings, cams, and functional components that need to be manufactured in the millions. 

Metal injection molding (MIM) unlocks geometries that axial pressing cannot achieve: undercuts, threads, wall thicknesses as thin as 0.4 mm, and three-dimensional free-form surfaces – straight from the process, without costly post-processing. In series production, MIM components reach densities of minimum 96% and higher, along with mechanical properties comparable to forged parts. 

Our sintered metal components at a glance 

 

  • Seat adjustment systems: Stops, outer rings, and functional components for electric seat length and height adjustment – manufactured using axial pressing or MIM depending on geometry. Tight tolerances for quiet, play-free operation. 
  • Seatbelt pretensioners & retractors: Functional components for pyrotechnic and electromechanical seatbelt pretensioners and retractors – safety-critical components that must respond reliably within milliseconds in an emergency. Sintered metal components from the axial pressing process offer outstanding dimensional accuracy and process reliability in large-scale production, while MIM enables complex geometries for miniaturized designs. All safety-relevant components are 100% tested. 
  • Mirror adjustment: Output gears and bevel gears for electric mirror adjustment – compact, lightweight, and designed for a long service life, produced economically in large volumes with axial pressing.
