Note: Annealing Stainless Steel Braids
Objective:
To heat stainless steel braids for an annealing application in the medical device industry.
End Product:
Steel braid
Equipment:
Ambrell EASYHEAT 6 kW, 150-400 kHz induction heating power supply with a workhead and coil specifically designed for this application.
Materials:
Stainless steel braids
Temperature:
1,000 °F (538 °C)
Frequency:
335 kHz
Testing:
A specially-designed multiple-turn helical coil was used to generate the required heating for the application. Initial tests were conducted to optimize the power delivered to the art. Once a satisfactory heat pattern was achieved in the time frame allowed, samples were run at multiple settings. Heating took just 2-5 seconds depending on the sample used, meeting the client’s requirements. This application is a new process for a high-volume production environment.
Benefits:
-
Speed: Induction met the client’s time requirements.
-
Space: Induction is friendly from a space perspective in a production environment as the power supplies are compact and the workhead can be placed away from the power supply.
-
Repeatability: Induction delivers the same result every single time when using the same part, making it an ideal heating process for production.
-
Efficiency: Induction is highly efficient, only heating where required and it is instant on/off, making it a greener choice.
