Product Description

Full Digital IGBT Induction Heating Machine for Portable Annealing Industrial Component Heat Treatment

As a professional manufacturer of portable induction heating machines, we specialize in delivering high-performance, compact, and mobile heating solutions for a wide range of industrial applications. Our machines leverage advanced electromagnetic induction technology to generate rapid, localized, and flameless heat directly within conductive metal workpieces—making them ideal for demanding field operations and workshop environments alike.

Key Advantages of Portable Induction Heating Machine

Ultra-Fast & Efficient Heating
Our portable induction heaters convert over 90% of input energy directly into heat within the workpiece, achieving heating speeds up to 10 times faster than traditional resistance or flame-based methods. For example, 1 kg of steel can be heated from 20°C to 800°C in just five seconds.
Flameless & Safe Operation
No open flame, no combustion gases, and no hot surfaces on the coil itself. This makes our equipment safe to use in confined spaces, near flammable materials, or in environments where open flames are strictly prohibited.
Precise & Localized Heating
By designing custom induction coils, heat can be concentrated exactly where needed—minimizing thermal distortion, reducing oxidation, and preserving the material properties of surrounding areas. Temperature control is accurate to within ±2-5°C.
Compact, Lightweight & Portable
Our handheld and mobile units are designed for maximum flexibility. The heating head weighs as little as 0.9-5.5 kg, with cable lengths of 3-6 meters, allowing operators to easily reach complex or hard-to-access workpieces on the factory floor or at outdoor job sites.
Energy-Saving & Eco-Friendly
Induction heating eliminates standby heat loss and can save approximately 40% energy compared to traditional high-frequency tube furnaces. It produces zero emissions and contributes to a cleaner, quieter, and more comfortable working environment.
Easy to Operate & Maintain
Featuring digital displays, PLC control interfaces, and built-in protection systems (over-current, over-voltage, water shortage, overheating, etc.), our machines are user-friendly and require minimal training. The simple, robust design ensures long service life and low maintenance costs.

Application: Inner Hole Heating

One of the most distinctive strengths of our portable induction heating machines is their exceptional capability for inner hole heating. By utilizing specially designed coils—such as hairpin-type, spiral, or conical coils inserted directly into the bore—our equipment can rapidly and uniformly heat the internal surfaces of holes, pipes, and cylindrical components.

Portable Induction Heating Machine Applications

Shrink Fitting / Hot Assembly
Heating the inner hole of components such as bearings, gears, couplings, and pulleys causes them to expand, converting an interference fit into a clearance fit for effortless, force-free installation. Once cooled, the component contracts to form a strong, reliable joint.
Inner Hole Quenching & Hardening
Our machines can perform precise surface hardening on the inner walls of cylinders, hydraulic support barrels, and gear bores, significantly improving wear resistance, corrosion resistance, and service life.
Inner Hole Annealing & Stress Relief
For components that have undergone prior hardening processes (e.g., carburized gears), localized induction annealing of the inner hole restores ductility and relieves internal stresses without affecting the hardness of the outer surface.
Bolt & Fastener Heating
Specialized hairpin coils can be inserted into axial holes of large bolts (e.g., in steam turbines or offshore structures) to heat them rapidly for easy nut removal or assembly—up to 10 times faster than conventional resistance bolt heaters.
Pipe-in-Pipe (PIP) Inner Pipe Heating
In the offshore oil and gas industry, our technology can heat the inner pipe of coaxial pipe assemblies to prevent or melt hydrate formation, ensuring smooth fluid flow in deep-sea environments.
Induction Brazing & Welding in Confined Spaces
The compact heating head can access narrow gaps and inner cavities for brazing copper tubes, stainless steel pipes, compressor components, and transformer joints—widely used in HVAC, refrigeration, and automotive industries.
