INDUCTION HEATING MACHINE :
Induction heating is a growth sector, and for good reasons. The
technique is energy efficient, reliable, reproducible, very fast
and its range of possible applications is almost unlimited. For
example, induction can be used on parts to heat, join, braze,
harden, or even melt them. A critical component in these processes
is the inductor. Its design is crucial in determining how precisely
a part is heated. Complex manufacturing processes are therefore
used to produce this central tool with precision to a tenth of a
millimeter—a task perfectly suited to the experts at our factory
.Our factory's technicians have a thorough understanding of the
different applications of induction heating. For more than 25
years, they have been developing inductors to match, which are
adapted to the geometry of the workpiece with painstaking
dimensional accuracy.
The crucial quality in induction heating is best summarized by the
word “precision.” The technology is used anywhere where a lot of
energy or heat needs to be applied to a workpiece in a very short
time. Temperature accuracy plays an important role here and is
often process critical – and precise heating is only possible with
the right mix of inductor geometry, frequency, power, and magnetic
field characteristics. Furthermore, the application of energy
through induction ensures fast production processes, minimal
workpiece distortion, and economical energy consume
When an alternating electrical current is applied to the primary of
a transformer, an alternating magnetic field is created. According
to Faraday’s Law, if the secondary of the transformer is located
within the magnetic field, an electric current will be induced.
THE ADVANTAGE OF INDUCTION HEATING MACHINE :
1. High Efficiency & Energy Saving
- Utilizes electromagnetic induction principle to directly heat
conductive materials (metals/metals alloys), achieving energy
conversion rates of up to 90%, significantly reducing waste heat.
2. Fast Heating Speed
- Enables rapid temperature rise (up to 1000°C in seconds) for
precise thermal processing, ideal for brazing, soldering,
annealing, and hardening.
3. Precise Temperature Control
- Equipped with advanced PID (Proportional-Integral-Derivative)
technology for ±1°C accuracy, ensuring consistent heat treatment
outcomes.
4. Non-Contact Heating
- Avoids direct physical contact, minimizing contamination,
oxidation, and material deformation. Safe for sensitive components.
5. Versatile Applications
- Compatible with ferrous/non-ferrous metals (steel, aluminum,
copper, titanium) and various industrial processes (welding,
induction forging, thermal forming).
6. Compact & Portable Design
- Lightweight and easy to operate, suitable for workshops, labs, or
on-site fieldwork with adjustable power output (5kW–50kW range).
7. Safety Features
- Includes overcurrent protection, automatic shutoff, and thermal
sensors to prevent overheating and ensure operator safety.
8. Environmentally Friendly
- No open flames or harmful emissions, meeting international
environmental standards (e.g., EU EMC regulations).
