Note: Heating stainless steel inserts
Objective:
To heat stainless steel inserts for the automotive industry
End Product:
Stainless steel inserts
Equipment:
Ambrell EASYHEAT 2 kW, 150-400 kHz induction heating power supply with a remote workhead containing two 0.17 μF capacitors for a total of 0.34 μF.
A six position three-turn helical induction heating coil designed and developed for this application
Materials:
Stainless steel metal inserts (3/8 in/9.5 mm long, an OD of .25 in/6.4 mm and an ID 0.1875 in /4.8 mm)
Temperature:
500 °F (260 °C)
Frequency:
230 kHz
Testing:
The inserts, with temperature indicating paint applied, were placed inside the six position helical induction heating coil and the power was turned on. The parts heated to 500 °F (260 °C) within ten seconds. The client had been using ultrasonic heating to press in the inserts which took 90 seconds.
Benefits:
-
Speed: Induction offers dramatically faster heating when compared to ultrasonics
-
Increased production: Faster heating means there is the potential to dramatically increase production rates
-
Repeatability: Induction is highly repeatable and easy-to integrate into manufacturing processes
-
Energy efficiency: Induction offers fast, flameless, instant on/instant off heating
