We're pleased to announce that a new brochure which highlights induction shrink fitting is now available. This brochure, which is titled "Improved Shrink Fitting with Induction Heating," highlights ten shrink fitting applications that were tested by THE LAB at Ambrell. It also discusses what shrink fitting is and why induction is often a good heating choice for the application. 

A client reached out to THE LAB at Ambrell because they needed to heat an aluminum motor housing to 464 ºF (240 ºC) for a shrink fitting application. The system will be used within an automated line. THE LAB determined that an Ambrell EKOHEAT^® 45 kW, 50-150 kHz induction heating system with a single position nine-turn internal bore coil would be optimal for this shrink fitting application.

A client contacted THE LAB at Ambrell because they needed to shrink fit a carbide ring into a valve seat. The materials that were used during testing were a steel valve seat and a carbide ring. THE LAB determined that an EASYHEAT^TM 10 kW, 150-400 kHz induction heating power supply with a three-turn helical coil to heat the steel valve seat would be the correct solution for this shrink fitting application. 

A manufacturer of pistons approached THE LAB at Ambrell with a shrink fitting application. They had been using an inexpensive portable induction unit, but found it unreliable for their application. Their application involved heating magnetic steel pistons for shrink fitting onto a chrome shaft. The target temperature was 1,100 °F (593 °C).
