Frequency and power judgment of ultrasonic welding machine

The difference between the frequency and power of ultrasonic welding machine is essentially understood that ultrasonic is also a kind of sound wave, and the frequency is closely related to the wavelength. When ultrasonic welding, the wavelength is related to the vibration amplitude of the ultrasonic equipment. For the welding of plastic and plastic components, generally speaking, the larger the volume, the lower the vibration frequency and the lower the ultrasonic equipment should be selected. At the same time, for equipment with very small volume, selecting a higher frequency equipment will make the welding effect more prominent.
Personnel engaged in ultrasonic plastic welding machine industry should know:
1> Ultrasonic plastic welding machines are classified according to their automation level:
1. Manual ultrasonic plastic welding machine
2. Semi automatic ultrasonic plastic welding machine
3. Full automatic ultrasonic welding machine
2> Ultrasonic waves are classified according to power
1. Low power ultrasonic welding machine
2. High power ultrasonic welding machine
Note: Low power ultrasonic welding machine refers to ultrasonic welding machine less than 2600W, and high power ultrasonic welding machine refers to ultrasonic welding machine more than 2600W.
3> Ultrasonic waves are divided into:
1. 15KhZ ultrasonic welding machine
2. 20KHZ ultrasonic welding machine
3. 35KHZ ultrasonic welding machine
4. 40KHZ ultrasonic welding machine

When we are faced with a plastic plastic component, we should specifically look at what material it is, and see if it is suitable for ultrasonic welding machine. If it is suitable for ultrasonic welding machine, what kind of ultrasonic welding machine should be selected for better effect, and what kind of ultrasonic welding machine should be selected for lower scrap rate. If we do not have professional technical testing or debugging, it is best to send samples to professional manufacturers such as Shenzhen Hengbo Ultrasonic for debugging when purchasing
15kHz has a low frequency and high power, suitable for larger welding products. The frequency of 20kHz is high and the power is small, suitable for welding products with small areas. Choosing different frequencies for different products cannot be compared equally. Choosing good ultrasonic equipment can improve production efficiency and welding effectiveness for enterprises.
Difference 1. Different frequencies: The oscillator of 15K ultrasound vibrates tens of thousands of times per second. 20K ultrasonic waves vibrate 20000 times per second.
Difference 2. Power difference: The power of 15K ultrasound is higher than that of 20K ultrasound.
Difference 3. Different dimensions and appearance:
The 15k oscillator should be longer, and the diameter of the ceramic chip should be above 60mm. The specification of the mold connecting screw is M16 * 1,
20k single oscillator, ceramic chip diameter 50mm, thickness thinner than 15, mold connection screw standard 3/8
