Semi solid metal (SSM) casting: Applications and case stories in aluminum and magnesium
- Buhler Inc., Uzwil (Switzerland)
A semi-solid metal (SSM) casting process based around real time controlled horizontal cold chamber die casting machines is described. SSM casting has been successfully applied to both aluminum and magnesium alloys with the largest shot weight to date being 11.5 kilogram (25 pounds). SSM casting offers a unique combination of near net shape and premium quality mechanical performance. Aluminum components generally require either partial (T5) or full (T6) heat treatment providing attractive combinations of strength and ductility. In the case of magnesium alloys, the ability to completely eliminate liquid metal handling from the casting floor allows SSM casting to compete with magnesium cold chamber die casting. In these instances, less massive gating than for aluminum is required and normal trimming operations can be considered. A series of case studies are presented together with projections for future developments. As raw material costs decrease and secondary recycling becomes viable it is expected that SSM casting will be considered for a much wider range of applications.
