High-frequency heat sealing machine is a high-frequency equipment, self-stimulated oscillator by the electron tube to generate high-frequency electromagnetic field. The object being processed in the high-frequency electromagnetic field is pressed between the upper and lower motors, the media material in the high-frequency electric field under the action of molecular polarization phenomenon, and according to the direction of the electric field is arranged because of the high-frequency electric field, to change the direction of the very fast speed, the internal molecules of the media material is excited by high-speed movement of friction with each other to generate their own heat, the pressure in the mold to achieve the fusion or embossing purpose. The main models are high-frequency synchronous fusing machine, single-head push plate high-frequency machine, single-head turntable high-frequency machine and so on.
