Die-Casting
Tempel manufactures aluminum die cast rotors to a variety of customer specifications. Capabilities include shaft installation, keyway broaching, reaming, burnishing and quenching.
- Aluminum Rotor Die-Casting: Rotor sizes range from ½" (12mm) to ~11" (279mm) OD and up to ~14" (356mm) long and shots weight to 30 lbs (13.6 Kg). Close monitoring of our furnaces ensures high quality molten metal, which translates to both high conductivity and tight control of porosity.
- Keyway Cutting and Broaching: We have key seated and broached a variety of geometries up to 12" (304.8mm) in length for frame sizes up to NEMA 440.
- Rotor Quenching: In order to improve efficiency of rotors, we often perform quenching operations either directly after aluminum casting or as a later operation. The quench process uses the differences in steel and aluminum contraction rates to break the conductor bars from the steel substructure, creating a higher efficiency core.
- Rotor Shaft Insertion: We have the ability to take the assembly of the rotor a further step and insert the shafts. This provides a completed subassembly that only needs balancing to be installed in your motors.
- Rotor Turning" Turn 10" (254mm) OD rotors, and hold .002" (0.0508mm) tolerance.
If your needs exceed our current range of production capabilities, Tempel will evaluate expanding our capabilities to meet your needs. Please contact
