induction shrink fitting

What is Shrink Fitting?

Induction Shrink Fitting refers to the use of utilizing Induction Heating to heat metal components between 302 degrees F (150 degrees C) and 572 degrees F (300 degrees C) causing them to expand and allow for insertion or removal of another component. Typically the low temperature range is used on metals such as aluminum and the higher temperatures are used on metals such as low/medium carbon steel. The process avoids changing mechanical properties while allowing components to be worked.


Aluminum, Carbon Steel, Carbide


  • Power on demand – rapid heat cycles
  • Eliminates a need for continuous power to other methods such as ovens where ambient temperatures must be consistently maintained
  • Heats the metal directly and not the ambient air as in convection processes

Typical Applications

  • Gear Housings
  • Bearing assemblies
  • Precision Tools
