Note: Heat a Fixture for a Wire Heating Application
Objective:
Heat a non-magnetic metal alloy shape-setting fixture for a Nitinol wire heating/shaping application.
End Product:
Nitinol wire
Equipment:
Ambrell EASYHEATTM 6 kW 150-400 kHz induction heating system with a workhead and coil specifically designed for this application
Materials:
Non-magnetic alloy fixture
Temperature:
977 °F (525 °C)
Frequency:
249 kHz
Testing:
THE LAB determined that a specially-designed single position multiple-turn channel coil would be optimal for this application. Temperature indicating paint was applied to the part so it would clearly indicate when the fixture achieved 977 °F (525 °C). It took seven minutes for the EASYHEAT to heat the fixture to temperature. An oven had been heating this fixture to temperature in twelve minutes.
Benefits:
-
Speed: The client had been using an oven, and induction shaved five minutes off of the heating time
-
Footprint: An EASYHEAT and its workhead require a minimal footprint, whereas an oven requires a significant footprint
-
Energy Efficiency: Induction heating is more efficient than an oven; with induction only the fixture is heated
-
Lower Maintenance Costs: Ovens can have significant maintenance costs and downtime with requirements such as relining
