Automotive Process Induction Shrink Fitting Case Study

2nd September 2020

Inductelec systems are used in the automotive industry to shrink fit gears and rings. Shrink fitting overview - Metals will generally expand when heated and contract when cooling. This increase in size in response to temperature increase is known as thermal expansion. Induction shrink fitting is where we use this effect to either fit two parts together which are tightly dimensionally toleranced. One component is heated to between 150°C and 300°C which causes it to expand allowing the insertion or overlaying it to the mating component. When the adjoined parts return to ambient temperature, the joint becomes strained and strong shrink fitted. Find out more at www.inductelec.co.uk/automotive-process-induction-shrink-fitting
