Ordinary heating coil heating method
Contact heat transfer heating.
1. 30-70% of power consumption is converted into working heat.
2. Heating must transfer heat energy through contact.
3. Both heating and cooling have inertia phenomenon, and heating and cooling are slow.
4. Heating has dead corners and cannot be completely wrapped in the outer layer of the barrel.
5. The heating ring has a large loss and a short life.
Electromagnetic Heater
Non-contact Electromagnetic Heater.
1. 95% of power consumption is converted into working heat.
Coil losses ≈ 2%, control unit losses ≈ 2%, and the insulating layer can retain 98% of the energy on the barrel.
2. Only the barrel is heated, while the screw remains cool.
3. Eliminate the inertia phenomenon of heating, heating and cooling quickly and efficiently.
4. There is no dead angle for heating, and the whole barrel is evenly heated.
5. The electromagnetic coil is kept cool, so the service life is super long.
