What Is The Difference Between 15KHZ Ultrasonic Transducer Vibrator And 20KHZ Ultrasonic Transducer Vibrator

Low ultrasonic frequency will produce noise, when the frequency is lower than 20kHz, the noise becomes very loud during ultrasonic welding. For plastic products with higher welding accuracy, the higher the frequency, the better. Therefore, ultrasonic welding machines with 20kHz or higher frequency are suitable for precise, ultra-thin, and very fragile plastic parts, such as SD cards, or products with crystal oscillators inside the product; The power of 15KHz ultrasonic welding machine is easier to make large, the amplitude is also relatively large, suitable for welding larger, difficult to weld, relatively 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 inverted conical, the screw hole specification is M16X1.0 teeth, and the 20kHz ultrasonic welding machine transducer is generally cylindrical, the diameter is also small, and the screw empty specification is imperial 3/8 when 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 product that can be welded is small.
