Electromagnetic Induction Band Heater
The electromagnetic induction band heater works by using the principle of magnetic field induction eddy current heating. The input power frequency 50Hz/220V alternating current is transformed into a 315V direct current through a rectifier circuit, and then converted into a high-frequency current with a frequency of 20-35kHz through the control circuit. When the high-frequency current passes through the coil, a high-speed changing magnetic field will be generated. When passing through the metal, countless small eddy currents are generated in the metal body, causing the metal itself to heat up at high speed.
Electromagnetic induction technology began to be used in the field of band heaters for plastic machines in the early 2000s. After nearly 10 years of development, electromagnetic induction technology has gradually become synonymous with energy-saving band heaters, and this has undergone fundamental changes after the emergence of infrared energy-saving band heaters . After nearly a hundred years, the improvement of band heaters has gradually kept pace with the development of the world economy.
