Using Induction Heating for Shrink Fitting

Feb 25, 2019 10:38:08 AM / by Brett Daly posted in Induction Heating, Shrink Fitting



Shrink fitting is a process where a size change after assembly, which can be achieved with induction heating, creates an interference fit. By heating or cooling one component prior to assembly and allowing it to return to the ambient temperature after assembly, the thermal expansion creates a joint. In fact, after the assembly cools, it generally cannot be separated without reheating the assembly to reverse the process.
