What is Induction Heating

Induction Heating PrincipleInduction Heating is the process of heating condutive material or magnetic condutive material (usually a metal, but also including graphite, molten salts, oxides, carbides, plasma etc.) by electromagnetic induction method, the changing magnetic fields generate changing electric fields (usually Eddy Current) in the object, and then the object generate Joule Heat by the induced electric fields by itself.

Advantage of Induction Heating

Induction heating is a quick, safe, clean, environmentally friendly heating method

Environmentally Sound

Induction heating systems do not burn traditional fossil fuels, induction heating is a clean, non-polluting process which will help protect the environment.

Reduced Energy Consumption

This uniquely energy-efficient process converts up to 95% of the energy expended energy into useful heat;
Batch furnaces are generally only 45% energy-efficient. And since induction requires no warm-up or cool-down cycle, stand-by heat losses are reduced to a bare minimum.

Improved Product Quality

With induction, the part to be heated never comes into direct contact with a flame or other heating element, the heat is induced within the part itself by alternating electrical current.

Maximized Productivity

Induction works so quickly, heat is developed directly and instantly (>1000℃. in < 1 second) inside the part.

Extended Fixture Life

Induction heating rapidly delivers site-specific heat to very small areas of your part, without heating any surrounding parts, this extends the life of the fixture

Optimized Consistency

Induction heating eliminates the inconsistencies and quality issues associated with open flame, torch heating and other methods.

What can induction heating do?

Induction heating can be used for most heating works,

including but not limited to:

  • Induction Brazing
  • Induction Welding
  • Induction Jointing
  • Induction Soldering
  • Induction Forging
  • Induction Melting
  • Induction Quenching
  • Induction Hardening

Induction Applications

Types of Our Induction Heating Machines

  • Ultra High Frequency Induction Heater
    UHF Induction Heater (Output Frequency>=250 KHz)

    Ultra-high frequency induction heaters are often used for quenching or hardening work, higher output frequency will bring thinner hardening depth and faster heating speed (some applications need 0.1mm~2mm hardening depth, then only ultra-high frequency machines can satisfy these works).

  • High Frequency Induction Heater
    HF Induction Heater (Output Frequency: 20KHz~250KHz)

    High frequency induction heaters are often used for hardening, brazing, welding , normal quenching, forging and forging work.

  • Medium Frequency Induction Heater
    MF Induction Heater (Output Frequency: 5KHz~20KHz)

    Medium frequency induction heaters are often used for forging or melting or big depth quenching works

  • DSP Air Cooled Induction Heater
    DSP Air Cooled Induction Heater

    Our DSP air cooled induction heaters can be used for preheating or postwelding works.

  • Induction Gold Melting Machine
    Induction Gold Melting Machine

    These integrated machines are used for melting gold or platinum

  • Air Cooled Induction Heater
    Air Cooled Induction Heater

    Our Full Air Cooled Induction Heaters are widely used for heating waters for homebuilding to provide heat in winter

  • Special Induction Heater & Other
    Special Induction Heater & Other

    We can also provide customized induction heaters for special works
