What technical requirements do we have when using ultrasonic welding machine?

1. High power capacity, stable ultrasonic generator: the requirement of stable ultrasonic generator is: frequency automatic tracking. Automatic frequency tracking can ensure that the sensor system can work in the resonant state, even if the amplitude of the welding head is amplified. The basic requirements for metal welding are to adopt automatic frequency tracking technology, change the mold and work without frequency modulation. The equipment using adjustable inductance to manually adjust the frequency cannot meet the requirements.
Stable ultrasonic generator also requires constant amplitude function and stepless amplitude adjustment. Constant amplitude function, which can ensure the consistency of welding, is the key to stable production; The amplitude of stepless adjustment is to ensure the basic use of equipment, for example, by adjusting the parameters of copper and aluminum welding materials in the same equipment.
High power capacity: compared with plastic welding, metal welding requires a higher energy density and must have a relatively high power capacity. For example, a 20kHz machine basically requires a power capacity of more than 3000W. Many companies often make false statements about the power capacity, so we only need to compare with their plastic welding machines, because no one believes that the plastic welding machines are too high.
2. High quality welding head: As a kind of industrial use, metal welding must require long-life welding head.
3. High quality sensor: such as 20kHz sensor, it must be able to withstand the load of more than 3KW for a long time. Many frequency converter companies use ordinary plastic welding frequency converter, and it is difficult to distinguish the appearance, which is irresponsible.
4. High quality control system: It has three basic control modes of welding energy, time and height, and a variety of quality control software can meet different needs.
