There is no quality difference between 15khz and 20khz ultrasonic plastic welding machines, the only difference is that they are suitable for different products.
The ultrasonic welding machines common frequency are 15khz and 20khz. The higher the ultrasonic frequency, the better the welding accuracy, the smaller the power and the amplitude. we mainly introduce the difference between 15khz and 20khz ultrasonic plastic welding machine.
1. Noise difference:
The lower frequency ultrasonic welding machine will hear the noise. Normally when the frequency is in 20khz, we can hear the noise, if below it the ultrasonic welding becomes very noisy.
2. The ultrasonic welder transducer appearance difference:
From the appearance, we can also distinguish the transducer of 15kHz and 20kHz ultrasonic plastic welding machine.
15kHz ultrasonic welder transducer shape is like a inverted cone. The screw standard is M16X1, 20kHz ultrasonic welder transducer shape is cylindrical, the diameter is small, The screw standard is 3/8-24.
3. The ultrasonic mold size difference:
The height of the 15kHz ultrasonic mold is generally about 17cm, and the height of the 20kHz ultrasonic mold is about 12.5cm.
4.The ultrasonic welder power difference:
15KHz ultrasonic plastic welding machine power are 2200w-8000w; 20KHz ultrasonic plastic welding machine power are 1200W-6000W.
5. The applicable products difference:
For plastic products with high welding accuracy requirement and small plastic parts, the higher the frequency, the better the welding effect. Therefore, compared with 15khz machine, 20khz or higher frequency ultrasonic welding machine is suitable for precision and thin wall plastic parts, such as SD cards, or products with crystal oscillation inside the product.
For 15khz ultrasonic welder, the power and the amplitude is large, and it is easy to use. So it is suitable for welding large products, difficult to process, and rough plastic products.
