Note: Heating Copper Parts for a Burn-Off Application

Objective:

To heat copper battery lugs for a burn-off application

End Product:

copper battery lugs

Equipment:

Ambrell EKOHEAT 15 kW, 50-150 kHz induction heating system with a coil specifically designed for this application

Materials:

Copper battery lugs supplied by the client

Temperature:

400 °F (204 °C)

Frequency:

123 kHz

Testing:

A custom-designed multiple-position helical coil was built to generate the required heating for the burn-off application. Initial tests were conducted to optimize the power delivered to the part. Several coils were tested and the one chosen was selected due to its flexibility/versatility. The chosen coil can be expanded to a 12-position setup. The customer desired a 20 second cycle time, which THE LAB at Ambrell’s solution was able to achieve

Benefits:

  • Repeatability: Induction delivers the same result every single time, making it ideal for a high-volume application such as this one.

  • Speed: Induction has no warm-up time like an oven and was able to achieve the client’s cycle time goal for this burn-off application.

  • Footprint: Induction takes up a modest amount of floor space, especially when you consider that the workhead can be placed a distance away from the power supply. 

  • Safety: Not only is induction heating efficient, it also offers safety advantages as there is no open flame
