Induction heating machines
IGBT power supplies from 5 kW to 500 kW, supplied standalone or built into a PLC or CNC controlled machine.
We use induction to heat the workpiece directly. An alternating current in a copper coil creates a magnetic field that induces currents in the part. Electrical resistance converts those currents into heat, allowing us to concentrate heating in the area your process requires.
We have been designing and building these machines in Faridabad since 2001. Our range runs from 5 kW to 500 kW across medium, high and ultra high frequency, and the frequency is selected for the application rather than the other way round.
Medium frequency machines are specified for billet heating, end heating for forging, hand tool and auto component work, and shrink fitting of bearings, gears and motor housings. High frequency machines are specified for induction hardening of auto components, tractor parts, hand tools and agricultural tools, and for brazing.
Every machine can be supplied as a bare power supply, or as a complete system with the coil, the cooling, the handling and the control designed around your part.

Questions engineers ask
What power rating do I need?
Power is set by how much mass you must heat, how far you must raise its temperature, and how quickly. A small brazed joint may need 15 kW; a forging billet line may need several hundred. The power estimator on this site will give you a first-pass figure from those three inputs, and the real number comes from looking at your part.
What does IGBT mean in practice?
IGBT is the semiconductor switch used in the inverter. Compared with older thyristor and valve designs it switches faster and more efficiently, which means a smaller, lighter, cooler-running machine that wastes less of your supply as heat.
Can the machine be automated?
Yes. We build PLC and CNC controlled automatic machines around the same power supplies, sized to your application and production requirement.
