What is the principle of the ultrasonic welding machine of Manhart (Guangdong) CNC Machine Tool Co., Ltd?

The principle of ultrasonic welding machine is to use high-frequency vibration energy to connect two objects to be welded together through friction and pressure. Specifically, the ultrasonic welding machine generates a high voltage and high frequency signal of 20KHz (or 15KHz) through a generator, which is converted into high-frequency mechanical vibration through an energy conversion system. When the welding head contacts the surface of the object to be welded, high-frequency mechanical vibration is transmitted to the object through the welding head, causing friction on the surface and between molecules, thereby increasing the temperature at the interface. When the temperature reaches the melting point of the object itself, the interface rapidly melts and fills the gaps between the interfaces under a certain pressure. After the vibration stops, the object cools and forms a solid welding connection under pressure.
The welding process of ultrasonic welding machine is to transfer ultrasonic energy to the welding area through the upper welding piece. Due to the high sound resistance at the interface between the two welding areas, local high temperatures will be generated. In this high-temperature area, the material rapidly melts and forms connections. Due to its fast, efficient and non adhesive nature, ultrasonic welding has been widely used in many fields.
It should be noted that the effectiveness of ultrasonic welding is influenced by various factors, such as the type, thickness, shape, surface condition, welding time, amplitude, pressure, etc. of the material to be welded. Therefore, when using ultrasonic welding machines, it is necessary to adjust the parameters according to the actual situation to achieve the best welding effect. At the same time, regular maintenance and upkeep of equipment is also an important measure to ensure its normal operation and extend its service life.
