Induction heating is a process that uses electromagnetic fields to heat conductive materials. An electromagnetic field is generated by passing alternating current (AC) through a coil. When a metal workpiece is placed within this field, eddy currents are induced and generate heat into the material.

Unlike other heating methods, induction transfers energy directly into the part being heated without physical contact. This results in faster, cleaner, better controlled heating, making it a great solution for a wide range of industrial applications.

Energy Efficiency

Reduce energy consumption by focusing heat only where it’s needed, eliminating wasted heat.

Precision & Control

Induction allows for the ability to control heating patterns.

Increased Production Volume

Rapid heating reduces cycle time and increases production.

Safety & Cleanliness

No flame or combustion creates a safer environment. Induction is a clean and environmentally friendly solution.

Reduce Maintenance

Induction systems have minimal moving parts and contact wear. This reduces equipment maintenance and extends the system’s lifespan.

An induction power supply generates the alternating current required to create a rapidly changing electromagnetic field, which induces heat in a conductive material.

1. The induction power supply takes an alternating current and converts it to high frequency alternating current through a rectifier that converts the incoming AC to DC.
2. The DC converted is then passed through an inverter, which switches the DC back into high frequency AC.
3. The high frequency AC flows through a copper induction coil, generating a rapidly changing magnetic field around the coil. When conductive material is placed inside or near the coil, the magnetic field induces eddy currents within the part.
4. The induced eddy currents flow through the workpiece, encountering resistance within the material. The amount of heat generated will depend on the power and frequency of the power supply, properties of the material, and coil design.

Induction coil geometry plays a critical role in determining the efficiency, heating pattern, and effectiveness o the indction heating process. The shape and design of the coil are customized based on the part's size, shape, and heating requirements. Below is an overview of the most common coil geometries:
