High Frequency Induction Heating

Induction Heating

Induction Heating Description:

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, where eddy currents are generated within the metal and resistance leads to Joule heating of the metal. The induction coil itself does not get heated. The heat generating object is the heated object itself.

DragonPower induction heaters got ISO9001,Rohs, CE certifications and patent for innovation with its latest technology to get energy saving up to 30%-80%.

Features of Dragonpower Induction Heating:

1. Heating speed linked to the possibility of obtaining very high power density
2. Exact location of the heating effect thanks to the inductor design and an operating frequency perfectly adapted to the part to be heated

3. The possibility to heat at very high temperatures with an efficiency practically independent of the temperature

4. A process perfectly adapted to industrial medium-sized and mass production requirements

5. Easy automation of equipment,

6. Absence of thermal inertia (rapid start-up), 

7. Repeatability of operations carried out, 

8. Often extremely high heating efficiency, 

9. Absence of pollution from the source of heating (cold source), 

10.Good working conditions.

Application 1 - Blow Film Machine:

Application 2 - Blow Molding Machine:

Application 3 - Injection Molding Machine:

Application 4 - Cast Film Machine:

It’s mainly applied in injection, extrusion, blow filming ,blow moulding ,wire drawing ,granulating and recycling machines etc. The product application includes film, sheet, profile ,raw material etc. It can be used for heating the barrel, flange, die head, screw and other parts of the machine with the advantage of 30-80% energy-saving rate.

How does Induction Heating Work?

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, where eddy currents are generated within the metal and resistance leads to Joule heating of the metal. The induction coil itself does not get heated. The heat generating object is the heated object itself.
