Principles of High Frequency Welding

　　The principle of high-frequency electromagnetic field is generated by the self-excited oscillator of an electronic tube. The processed object is pressed between the upper and lower electrodes with high-frequency electromagnetic fields, and its internal molecules are excited and move at high speed, rubbing against each other to generate heat and melting, achieving the purpose of fusion or embossing under the pressure of the mold. High frequency waves refer to high-frequency waves.

　　High frequency waves and ultrasound are two different concepts. High frequency waves refer to electromagnetic waves with frequencies greater than 100 Khz, while ultrasound refers to sound waves with frequencies exceeding 20 kHz.

　　The welding principle and fusion principle of high-frequency waves are also different from ultrasonic waves. High frequency waves are generated by the oscillation of high-frequency electronic tubes, which cause intense collisions between molecules inside the material and generate high temperatures to achieve the purpose of welding and fusion. Ultrasound, on the other hand, utilizes the principle of frictional heat generation to generate a large amount of heat for welding and fusion purposes. High frequency applications are widely used, including high frequency plastic fusion machines, high frequency sliding table fuses, high frequency disc fuses, high frequency disc machines, high frequency medical specialized machines, high frequency automotive industry specialized machines, high frequency metal heating machines, high frequency standardized factories, standardized equipment, and industry specific non-standard equipment.
