[October 1, 2009]  Inductoheat, Inc., an Inductotherm Group company, shipped a new Simultaneous Dual Frequency Induction Gear Hardening System to a leading supplier of automotive engine and powertrain components.  This machine was designed specifically for heat treating a medium size gear.

Inductoheat’s system is rugged and can be used for high-volume single-shot hardening of several powertrain components dramatically minimizing distortion of heat treated parts and providing superior hardness pattern with favorable distribution of residual stresses.

The total power exceeds 1,200 kW comprising a medium frequency (10 kHz) and high frequency (120 kHz – 400 kHz) modules working simultaneously or in any sequence desirable to optimize properties of the gears heat-treated using this unique technology.

Utilization of the standard platforms for manufacturing medium and high frequency modules substantially reduces the cost of simultaneous dual-frequency systems.

Allen Bradley controls with PC touch screen operator interface offers superior process control and monitoring capabilities assuring the highest quality and repeatability of any induction system. Integrated closed-loop, water recirculation system reuses water for quenching and cooling.

Other features include:

  • High-speed servo spindle drive for precise control of rotation speed during heat and 

    quench.

  • Heavy-duty aluminum splash door with safety interlock switch and light curtains.

  • Robust system components with advanced QA, precise position control and safety

    measures.
