Do you know the advantages of electromagnetic induction heaters?
Since the beginning of the 20th century , people began to experiment with industrial applications of induction heating . The theory of induction heating has been matured , various induction heating devices have emerged , and industrial applications of induction heating have also expanded , such as metallurgy , metal melting , heat to transfer ， heat treatment , and paper , etc . Civil heating is also being used more and more , such as induction furnace , induction welder , and electromagnetic water heaters . It should be said that the electromagnetic induction technology is now quite mature , and its advantages are becoming more and more obvious . At present , it has become the research and application selection direction of many enterprises technological innovations .
Advantages of electromagnetic induction heater products:
1, reduce maintenance costs
The heating part is made of high temperature resistant insulating material and cable material. The heating cable itself generates low heat, and there is no problem that the heating wire of the original coil is aged at a high temperature to shorten the life, so the service life is long.

2, large heating power
When the traditional resistance wire of the injection molding machine barrel is too large , the damage to the resistance wire itself will be greatly increased . The resistance wire metal itself will rapidly evaporate at high temperature , and will quickly age and fail . Therefore , the conventional resistance wire needs to be replaced occasionally , and the number of wires is increased . Production cost and production efficiency ; high-frequency energy-saving heating system is characterized by high temperature only inside the metal of the inductive barrel and the temperature of the heating system itself is very low , and its own electrical loss is negligible , so even if the power is large , it does not affect the heating . The service life of the system can be adjusted at any time as needed .
3, a substantial saving from electrical energy
The heating method used for the plastic mechanical barrel is the heating of the traditional electric heating ring (ie , the resistance wire ) , and the heat is transmitted to the barrel of the contact conduction method , and only the heat immediately inside the surface of the barrel is transmitted to the barrel , and the electric heating circle Most of the heat of the outside is lost to the air , and there is a large amount of heat loss , which causes the workshop to be hot and humid . The electromagnetic heating system completely solves such a problem , and a layer of heat insulation layer is added between the induction coil and the barrel , and the heat of the barrel is slightly radiated from the air , and the temperature of the surface of the barrel is below 50 degrees , after rigorous experiment . Test , saving energy in 30%-80% , especially for high-power injection molding machine power saving effect is more obvious .
