Electromagnetic Induction Heater 10KW for heating plastic injection molding machine


Magnetic Heater & Electromagnetic Induction Heater 10KW for heating plastic injection molding machine

Principle of Electromagnetic Induction Heating:

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 heating:

1.Energy saving and emission reduction (30-85%)

2.higher thermal efficiency

3.Reduced operating temperature

4.warm up fast

5’long service life

6.Maintenance is simple and convenient


What Advantages Does Induction Heater Have Compared With Traditional Heaters?

Advantage Comparison
Electromagnetic Induction Heater Traditional Heater
Heating Principles Electromagnetic Induction Heating the  Resdistance Wire
Heated Part Charging barrel is heated directly to get higher efficiency ,but the induction coil itself is not heated to guaratte longer using life heater itself,then heat transfered to the charging barrel
Surface Temperature & Safety Max. 60 Degree Centigrade,safe to touch by hands. The same with your heating temperature, Dangerous to touch
Heating Rate High Efficiency:save 50%-70%warming -up time Low Efficiency:No time-saving
Energy Saving Save 30-80% Power Consumption No Saving
Temperature Control High precision Low Precision
Using life 4-5year 2-3year
Working Environment Normal temperature for workers,easy and comfortable Hot,especially for low latitude Area
Cost Cost-effective,with30-80% energy-saving rate,it takes 6-10 months to recover the cost. The higher the rate is,the less time it takes. Low
