High frequency principle

The high-frequency principle generates a high-frequency electromagnetic field by a tube self-excited oscillator. The object to be processed is pressed between the upper and lower electrodes with a high-frequency electromagnetic field, and its internal molecules are excited and move at high speed to rub against each other to generate heat and melt, and achieve the purpose of welding or embossing under the pressure of the mold. High-frequency waves are high-frequency waves. High-frequency waves and ultrasonic waves are two different concepts. High-frequency waves refer to electromagnetic waves with a frequency greater than 100Khz, and ultrasonic waves refer to sound waves with a frequency exceeding 20 kHz.
