SSR Semi-Solid Rheocasting

Easy, reliable and efficient

SSR™ is a process patented by the Massachusetts Institute of Technology (brev. U.S. 6,645,323 – European patent N. 1322439) and acquired by IDRA with exclusive license, for the production of semi-solid alloy ready to be die casted.

Main specifications:

  • Possibility to produce high-integrity castings
    (that can be welded, heat- treated and with higher mechanical properties)
  • Possibility to produce typical-gravity castings at competitive cost
  • Reduction of cycle time (10 – 25 %)
  • Increase in die life


  • Slurry on demand
  • Low solid fraction
  • Suitable for almost any kind of alloys
