What is the difference between 15KHZ ultrasonic transducer oscillator and 20KHZ ultrasonic transducer oscillator

    What is the difference between 15KHZ ultrasonic transducer oscillator and 20KHZ ultrasonic transducer oscillator

Low ultrasonic frequency will produce noise, when the frequency is less than 20khz, the noise becomes very large when ultrasonic welding. For plastic products with higher welding accuracy, the higher the frequency, the better. Therefore, 20khz or higher frequency ultrasonic welding machine is suitable for precision, ultra-thin, very fragile plastic parts, such as SD cards, or products with crystal vibration inside the product; The power of the 15khz ultrasonic welding machine is easier to make, the amplitude is relatively large, and it is suitable for welding larger, difficult and easy to weld, and more rough plastic products.

Secondly, from the appearance point of view, the transducer of 15khz and 20khz ultrasonic plastic welding machine can be distinguished, the transducer of 15khz ultrasonic machine is generally conical, the screw hole specification is M16X1.0 teeth, and the transducer of 20khz ultrasonic welding machine is generally cylindrical, the diameter is also small, and the screw empty specification is British 3/8 hours 24 teeth.

Again, the 15khz ultrasonic plastic welding machine can weld larger workpieces, and the power can be divided into 2600w/3200w/4200w. The 20khz ultrasonic plastic welding machine is 900W-2000W, the power is small, and the size of the products that can be welded is small.
