What's the difference between high frequency and ultrasonic?
From: Dongguan run automation equipment Co., Ltd. Post date: 2017-07-26


High frequency and ultrasonic are two different concepts, high frequency refers to the frequency of electromagnetic waves greater than 100Khz, ultrasonic refers to the frequency of more than 20 thousand Hertz of sound waves. The principle of high frequency welding, ultrasonic welding principle and is not the same, is the use of high frequency high frequency electromagnetic field so that the material inside molecules to each other collision produces high temperature welding and welding to the purpose, and is based on the principle of ultrasonic friction heat heat produced by welding and welding to achieve.
High frequency applications are widely used, so there are high frequency plastic welding machine, high frequency leather plastic fuse machine, Gao Zhou twist box creasing machine, high frequency embossing machine, high-frequency heating machine and so on.
High frequency, high frequency wave. High frequency and ultrasonic are two different concepts, high frequency refers to the frequency of electromagnetic waves greater than 100Khz, Dongguan ultrasonic refers to the frequency of more than 20 thousand Hertz of sound waves. High frequency welding principle and welding principle and ultrasonic wave is not the same, is the use of high frequency high frequency electromagnetic field so that the material inside molecules to each other collision produces high temperature welding and welding to the purpose, and is based on the principle of ultrasonic friction heat heat produced by welding and welding to achieve.
High frequency self-excited oscillator generated by the tube taking frequency electromagnetic field, the processing of plastic on the high frequency electric field between the electrodes, the internal friction force from the movement of molecules, the welding purpose in the mold under pressure, welding effect.
