Ultrasonic welding is a high-tech technology, and all kinds of thermoplastic rubber parts can be processed by ultrasonic welding without adding solvents, adhesives or other auxiliary products. The advantages are improved production efficiency, low cost, high bonding strength and environmental protection.
The principle of ultrasonic plastic welding: the generator generates 15-40KHz (15/20/28/30/35/40KHz) high-frequency electric energy, and through the energy conversion system, the high-frequency electric energy is converted into high-frequency mechanical vibration, which is added to the plastic On the product, the temperature transmitted to the interface is increased by the friction between the surface of the workpiece and the inner molecules. When the temperature reaches the melting point of the workpiece itself, the interface of the workpiece melts quickly, and then fills the gap between the interfaces. When the vibration stops , The workpiece is cooled and shaped under a certain pressure at the same time to achieve perfect welding.
