RF power is applied until the part reaches the appropriate temperature. The induction coil is then quickly removed from the hole and the shaft that is to be inserted is then slid into position. The assembly is then allowed to cool.
Pressure develops as the heated component contracts.
Depending on the mass of the material to be expanded, a pancake-shaped coil is sometimes employed. Fast, precise heating works best. If the inner diameter and outer diameter are not held at tight tolerances, the shrink fit will not be possible. There can be no burs on the joining surfaces. If the two metal parts are not properly aligned, the shaft will not slide into the correct position.
