Energy saving principle of electromagnetic induction heating technology
At present, the heating method commonly used by heating equipment such as plastic machinery in the market is electric heating ring heating, which transfers heat to the heated body (barrel) through contact conduction. However, only the heat close to the inner side of the barrel surface can be well transferred to the heated body, while most of the heat on the outer side is lost to the air, resulting in heat conduction loss and causing the ambient temperature to rise. In addition, another disadvantage of resistance wire heating is low power density, which cannot meet the requirements in some occasions requiring higher temperatures.
