The Application in Plastics Industry
The heating temperature of the plastics industry is below 500 degrees, Such as plastic injection machines, extruding machine, blown film machines, wire drawing machines, plastic films, pipes, wires and other machines. The original mainstream heating method uses resistance heating. But because the heating way is the mode of heat conduction, its preheating time will take more than one hour. And ta lot of energy will be lost during heating, and the temperature can not be precisely controlled. Therefore after being reheated by induction heating, the heating time of the heating body is shortened, the loss of heat is reduced, and the temperature is controlled accurately, and the ambient temperature is lowered. At present, induction heating has become the mainstream heating method in various kinds of plastic equipment with relatively large power.
