Induction melting Benefits 

  • Meets tight production tolerances with precise localized heat to small areas creating pinpoint accuracy

  • Increases production rates with faster heating cycles

  • Reduces defect rates with repeatable, reliable heat

  • Eliminates variability from operator-to-operator, shift-to-shift

  • Maintains metallurgical characteristics of the individual metals
