Note: Shrink-fitting auto turbo charger impeller blades onto an aluminum shaft
Objective:
To heat aluminum impeller blades to 200 °F (93 °C) and shrink fit them onto shafts.
End Product:
turbo charger
Equipment:
Ambrell EASYHEATTM 3.5 kW, 150-400 kHz solid state induction power supply with a workhead and coil specifically designed for this application.
Materials:
Aluminum impeller blades with a .28 in (7.109 mm) bore, aluminum shaft
Temperature:
200 °F (93 °C)
Frequency:
255 kHz
Testing:
A split two-turn helical coil is used to evenly heat the opening on the impeller blade. The impeller blade is heated for 20 seconds to reach the target temperature of 200 °F (93 °C). The impeller blades are then removed from the coil and slipped over the shaft to complete the shrink fitting application.
Benefits:
Accurate and repeatable results
Reduced cycle time, lower consumable expenses
Even distribution of heating
Ease of integration into existing production lines
Energy efficient
Hands-free heating that involves no operator skill for manufacturing
