Working principle of high-frequency heating machine

The working principle of a high-frequency heating machine is that the dielectric material undergoes molecular polarization under the action of a high-frequency electric field, and is arranged in the direction of the electric field. Due to the high-frequency electric field, if the direction is changed at an extremely fast speed, the dielectric material will generate heat due to dielectric loss. By placing plastic such as polyvinyl chloride between electrodes and applying a certain pressure, the plastic can maintain this deformation after heating and cooling for a period of time. By utilizing this characteristic, high-frequency embossing or molding can be achieved. If two or more pieces of plastic are heated and melted, cooled and firmly bonded together, high-frequency welding can be achieved by utilizing this characteristic
