Be sure to watch the latest induction heating application video from THE LAB at Ambrell. It involves hardening a fastener tip with an Ambrell EKOHEAT^® induction heating system and a custom-designed channel coil. As you can see in the video, heating the stainless steel/carbon tip took less than three seconds. 

In this application video from THE LAB at Ambrell, a steel tool is heated to 1400 °F (760 °C) for an annealing application. An Ambrell EKOHEAT^® induction heating power supply is used. The red sight on the part is from a pyrometer, the temperature displays on the controller to the left, and there is temperature indicating paint down the part.

In the latest application video from THE LAB at Ambrell, a steel gear is heated to 400 °F (204 °C) for a shrink fitting application. An Ambrell EASYHEAT^TM 6 kW induction heating power supply is used. You'll see that temperature indicating paint -- which liquefies and turns clear when the target temperature is achieved -- is applied to two spots on the part. 

Check out the latest application video from THE LAB at Ambrell. The videos shows though-hardening of a cutting tool with an Ambrell EASYHEAT^TM induction heating system along with an optical pyrometer to measure temperature:
