Induction heating of aluminum

Induction heating of aluminum
  • Induction heating system designed by MSI Automation
    for the US Navy.
  • Complex system is controlled by a PLC.
  • Operator places as many as 500 housings into machine in 8 hour shift, one at a time.
  • Housing is placed into fixture and lower threaded clamp locks bottom half of housing, not shown from this view.
  • Lower clamp proximity sensor triggers heating cycle and timer controls heating for approximately 5 to 7 seconds.
  • Heat cycle terminates and upper clamp system closes on upper half of housing, not shown.
  • Bottom clamp system remains stationary.
  • Upper clamp system rotates 60 degrees and rises 10 mm, breaking the epoxy bond that cements two housing halves together.
  • Final motion: both clamp sets release housing and bottom side air cylinder pushes hot housing from fixture.
  • Operator removes housing and replaces with next housing.
  • Cycle repeats.
