How to choose the frequency of ultrasonic welding machine equipment

With the universal recognition of the advantages of ultrasonic welding technology, many industries have just begun to choose ultrasonic automatic welding machine equipment at this stage. In order to better consider the welding requirements of different industries, ultrasonic welding equipment has multiple frequencies Can enumerate, let's talk about the frequency selection of ultrasonic welding equipment.

The selection of ultrasonic welding machine equipment is a more complicated matter, and a variety of factors must be considered. When selecting an ultrasonic welding machine, one of the key considerations is the operating frequency. The operating frequency range of most equipment on the sales market is 20khz~40kHz, and the operating frequency of some equipment is 10~70kHz. For ultrasonic molds/or thick-wall welded parts, choosing a lower vibration amplitude will help reduce the resonance of welded parts. Most of the shocks can cause the welding parts to be destroyed. Enlarging the output power or increasing the vibration amplitude will increase the output power loss in the polymer. Therefore, in most cases, choosing a higher output power is a useful way to get a lower amplitude and a large output power.

After clarifying the output power, generally the output power size must be considered. The frequency of each product workpiece can generally have several output power levels. For example, the output power of 20kHz, the output power range of the ultrasonic welding machine provided by most equipment manufacturers is 1~5Kw. In most cases, the output power size can be determined in accordance with the required output power in the laboratory of dealers, scientific research organizations and universities. If it is not possible to clarify the required output power theoretically in advance, then select it to ensure that the equipment can consider the operating requirements. When selecting equipment, be sure to clarify the welding parts. If it is a surgical suture type welding part, most equipment manufacturers have this kind of standard equipment, and they can also provide many other standard rotating anvils with many patterns. Most anvils carry out laser cutting, sealing and electric welding.

Other equipment elements include control level, amplitude control, amplitude contour, and storage system control capabilities. For some applications, this option can improve the quality and density of electric welding. On the other hand, testing in the application laboratory can help determine which frequency must be selected.
