30KW Plastic Injection Molding Machine Electromagnetic Induction Heater
Principle of Electromagnetic Induction Plastic Injection Molding Heater:
Most of the metal is heated by the high-frequency magnetic field and uses this principle to pass the high-frequency current through the coil, so that the coil generates a high-frequency magnetic field, so that the metal rod in the coil is induced to generate heat. The electrical energy can be converted into metal thermal energy by the above process. During the whole process, the metal rod does not have any physical contact with the coil, and the energy conversion is completed by the magnetic field eddy current and the metal induction.
Advantages of electromagnetic induction plastic injection molding heater:
1.Energy saving and emission reduction (30-85%)
2.higher thermal efficiency
3.Reduced operating temperature
4.warm up fast
