Inflatable Toys High Frequency Welding Machine is a high frequency device, whose self-exited oscillator of the electron tube can produce high frequency electromagnetic field. And the plastic to be processed is in the high frequency electromagnetic field between the upper and low electrode. When its interior molecules are polarized and produce heat automatically by mutual movement and friction, it will be welded with the pressure of the die.
