Production technology

As a result of Häussermann's innovative technology, diaphragm springs have become a precision component for the automotive industry.


The strengths of superior technology: minimal-warp quench- hardening with:

  • adherence to the narrowest force tolerances;
  • cranking of fingers for the optimal utilization of the design envelope in one operation;
  • shot peening operation individually and with controlled parameters : increase in service life by a multiple of between 2 and 5; reduced variation of life inside the production lot;
  • Scragging and load testing interlinked with last operation: 100% safety;
