Select the right induction heating machine for forging, hardening, brazing, melting, annealing, tempering and custom automated production. LJ Induction helps you match the machine, power, frequency, coil and control system based on your workpiece and production requirements.
If you are still comparing induction heating with flame, resistance or furnace heating, read our guide to understand how induction heating works, what materials can be heated, and how power, frequency and coil design affect the heating result.
Don’t start from machine models. Start from your heating goal. Tell us what you want to achieve, and we will guide you to the right machine type.

For repeatable surface hardening of shafts, gears, pins, bearings and tools with controlled heating depth, stable hardness profile and reduced distortion risk.
For clean, localized and flame-free brazing of copper tubes, carbide tools, connectors, HVAC parts and metal assemblies with less operator dependency.
For controlled melting of steel, copper, aluminum, precious metals and alloys in foundry, laboratory and production environments.
Complementary induction technologies for specific metallurgical and production requirements.
For wire, tube, fasteners and local stress-relief applications where controlled softening or improved ductility is required.
For tempering after hardening, helping improve toughness, reduce brittleness and stabilize heat-treated parts.
For coating removal, paint removal, pipeline surface preparation and field maintenance without open flame.
For custom coils, automated heating stations, retrofit projects and production line integration.
For shrink fitting, bolt heating, preheating, disassembly, localized heating and custom applications.
Induction heating performance depends on material conductivity, part geometry, heating depth, coil access and production rhythm. Share your workpiece details and we will evaluate the process feasibility before recommending a machine.

Our engineers will check the material, heating zone and coil access first.
A suitable machine is not selected by kW alone. The real heating result depends on the match between power, frequency, coil geometry, cooling, temperature control and production cycle.
Power is selected according to workpiece size, target temperature, heating time and production volume. Higher power can shorten heating time, but oversized power without proper control may increase overheating risk.
Higher frequency is usually used for smaller parts and shallow surface heating (Skin Effect). Lower or medium frequency is often better for larger parts or deep through-heating for forging.
The coil shape, gap, loading method and fixture design directly affect heating efficiency. Minimizing the gap between the coil and workpiece surface reduces flux leakage and maximizes electrical efficiency.
Industrial systems require stable cooling for the power supply and coil. Cooling configuration must match machine power, ambient temperature and continuous working time (Duty Cycle).
Heating can be controlled by time, power setting or PID digital temperature feedback. Our systems maintain ±1% stability, ensuring consistent results between batches via recipe-based management.
