Induction Metal-to-Plastic Insertion for Cooling Fan Shafts | Ambrell


Heat Staking with Induction


A supplier to the automotive industry was looking to heat a cooling fan shaft for a metal-to-plastic insertion (heat staking) application. They needed to heat the end of the shaft to 572 oF (300 oC) within three seconds. They turned to the application engineers at THE LAB at Ambrell to come up with a solution. 

An Ambrell EASYHEATTM 2 kW (150-400 kHZ) induction heating solution was determined to be the right system for the application. A custom-designed single position multi-turn split helical coil was built to generate the required heating for this application. Temperature indicating paint was then applied to the part, which dissolves when the part reaches the target temperature. It took just one second to heat the part to temperature, which exceeded the client's heating time goal.  

 

The client turned to induction heating from Ambrell for a number of reasons. First off, THE LAB at Ambrell was able to design a solution that exceeded their requirements. Additionally, the EASYHEAT requires a minimal footprint, heated the part rapidly, and the process is highly repeatable. Finally, induction heating doesn't introduce a flame into the work environment.
