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).

A client in the oil and gas industry came to Ambrell with a shrink fitting application. They had been using a cold method for inserting carbide buttons into hammer bits, but wanted to look to induction heating. They took advantage of THE LAB at Ambrell's complimentary applications testing to determine the feasibility of their shrink fitting application. 

A manufacturer of power generation equipment approached THE LAB at Ambrell with a shrink fitting application. They had been shrink fitting a magnetic steel gear with an oven, but that oven took over two hours to heat the gear to 550 °F (288 °C). Their hope was that induction could significantly reduce that time, which would increase their productivity and enable more throughput. They sent in their parts to Ambrell and took advantage of complimentary applications testing.
