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.
Main characteristics:
1)Infineon IGBT module and Inverting technologies of third generation been used; Higher reliability and lower maintenance cost.
2) 100% Duty cycle, continuous working is allowed at maximum power output.
3) Display of heating power and heating current and oscillating frequency.
4) Simple to install, Installation can be done by unprofessional person very easily;
5) Light weight
6 ) Advantages of the model with timer: the power and the operating time of the heating period and the retain period can be preset respectively, to realize a simple heating curve, this model is suggested to use for batch production to improve the repeatability;
7) The separated models are designed to fit the dirty surrounding of some cases.
8)Heating time can set 1-999S also can set 0.1-99.9S.
9)Water pressure meter install the machine, can check water pressure at the meter, easy to know whether your cooling system is enough or not.
10) Energy Saving Up to 20-30% compare with SCR machine.
11) Soft Switch Technology And prefect Protection system( Over Heat, Over Current, Under Voltage, Over Voltage, Phase Fail, Lack Water) enhance Good Reliability.
12) 4 Different working modes:
P0: Means work at the manual, the machine will Sequential timing, Timer 1 shows the heating time, Timer 2 shows working frequency, when you Press, then the machine stop it. If use the Foot Switch, Step On the Foot Switch not loose it, then the machine is working, loose the foot switch, then the machine stop heating.
P1: Means Work at time we set it before heating, Timer 1: means heating time( this is countdown count time, Timer 2: Display Working Frequency. For example: If you set heating time 20S, the machine will countdown count time, when finish 20S then stop the machine automatically. If use the foot switch, Step on the foot switch then loose is at once, the machine is working, when finish the heating time that we set, then the machine stop it automatically.
P2: 2 Sections Heating( Section 1 for heating, section
