Induction heater


Application 
Electromagnetic induction heater is mainly used in plastic(rubber)injection machine, extruder machine, film blowing, drawbench, pelletizer, and the equipment manufacture the film, pipe and wire. It also can be used in the heating of cylinder, flange, die head and screw.
Working theory:
Electromagnetic heating convert the alternating current at 50-60Hz to the intermediate frequency alternating current at 20-25Hz according to the electromagnetic induction principle, and converting to the alternating magnetic field through the electromagnetic wire, the closing rotary current(eddy current) produced while the metal subject close and feel the magnetic field, the current has heat effect. Thus to the high fever, and its heating purpose achieved. The magnetic wire won’t produce heat, and the heat element is the part be heated.
Components:
It is composed of control panel, mutual induction, control cabinet and the air cooling shell (when air cooling needed)
The advantages of electromagnetic induction heater compared with traditional heater
1.The energy saving rate can up to 30-50%, it can saving the energy consumption used in cooling environment. Such as the cost of electric fan and air condition.
2.The surface temperature of heater can down to 40-50℃ which won’t be hurt if touching. And it can down the temperature in workshop, which provide safety and conferment for workers.
3.It use the v type structure. It has the magnetic wire inside of the insulation layer, needn’t wrap the wire self, and can be install directly. Its convenient and fast.
4.The preheat time of equipment can short at least 1/3, it improves the produce effective greatly.
5.The precision temperature control improve the quality of plastic products.
6.Its working can be more then 2 years under the appropriate operation and maintenance.
7.The energy saving rate at 30-50%shorten the cost recovery period. The cost can be recovered after 6-9months under normal condition. And the higher the energy saving rate, the shorter the cost recovery period.
