Float ball welding of float valve

The principle of ultrasonic welding: when the ultrasonic plastic touches the thermoplastic plastic contact surface, it will generate tens of thousands of high-frequency vibrations per second, resulting in local high temperature. Due to the poor thermal conductivity of the plastic, it cannot be distributed in time, and it is gathered in the welding area, which causes the contact surface of the two plastics to melt quickly. After a certain pressure is added, it is merged into one.
