Electromagnetic induction heating technology can be widely applied in plastic machinery (such as blowing film machines, drawing machines, injection molding machines, granulating machines, and vulcanizing machines), food machinery, oil heating and conveying, chemical machinery, and other heating industries. Electromagnetic induction heating equipment, with its simple operation, convenient use, fast heating speed, high thermal efficiency, and significant energy-saving effect (reducing electricity consumption by 50% to 80%), is gradually becoming the terminator of traditional heating equipment.
