About Induction heating machine :
Induction heating is a process which is used to bond, harden or soften metals or other conductive materials. For modern manufacturing processes, induction heating offers an attractive combination of speed, consistency, control and energy efficiency.
   The basic principles of induction heating have been understood and applied to manufacturing since the 1920s. During World War II, the technology developed rapidly to meet urgent wartime requirements for a fast, reliable process to harden metal engine parts.
More recently, the focus on lean manufacturing techniques and emphasis on improved quality control have led to a rediscovery of induction technology, along with the development of precisely controlled, all solid state induction power supplies.
How induction heating works?
   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.
In a basic induction heating setup, a power supply sends an AC current through an inductor (often a copper coil), and the part to be heated (the workpiece) is placed inside the inductor. The inductor serves as the transformer primary and the part to be heated becomes a short circuit secondary. When a metal part is placed within the inductor and enters the magnetic field, circulating eddy currents are induced within the part.

Our Machine features :
 1Fast IGBT drive circuit
Obviously improve the resonance waveform and reduce the dead time.Further reduce the switching oss and increase the stability of high frequency tracking.At the same time each IGBT drive has short circuitprotection and under voltage protection.
2.High reliability design and stringent factory assembly and testing
Each power supply has been tested at OURUIDA plant for high-power operation,aging and removing unstable components,so as to ensure that each power supply has the capability of continuous high- bower operation for months without interruption.
3.Uninterrupted operation design
In the case of quick cut or flicker of the power supply circuit or accidental protection,the device can make automatic diagnosis and automatically return to normal operation state (automatic restart) to avoid production loss caused by shutdown.
he energy applied to the workpiece can be controlled and based on this energy temperature control, restriction and protection can be carried out to meet the requirements of high-level and complex process control.
4.Accurate and fast internal control
When the output current measurement and control resolution reaches 0.1A,the output is stable and unfluctuating, and the control speed is not affected.
5.Insulation resistance online monitoring
Runtime real-time insulation resistance measurement circuit and display (for example, 8.2 M2) and can be set up and implement protection.
6.Fast automatic phase-frequency tracking technology based on reactance analysis
Solve the problems of "lock90-cycle" such as phase instability, frequency deviation, capacitive switching. and narrow tracking range and so on.
The switching loss of IGBT can be reduced by more than 30% at high frequency.
Within 10 times of designed frequency range of device can accurately track and maintain the IGBT zero switch.
7.Four basic operating modes
Constant current operation, Constant power operation, Constant temperature operation,Process program operation(The last two are optional)
Each operation mode can be combined with eneray control, timing, fast cvcle control and other functions.
