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
