When ultrasonic wave acts on the contact surface of thermoplastic plastics, it will produce tens of thousands of high-frequency vibrations per second. This kind of high-frequency vibration reaches a certain amplitude and transmits the ultrasonic energy to the welding area through the upper weldment. Due to the large acoustic resistance at the interface between the two welding areas, local high temperature will be produced. Because of the poor thermal conductivity of the plastic, it can not be distributed in time, and gathered in the welding area, resulting in the rapid melting of the contact surface of the two plastics, and after adding a certain pressure, they are integrated into one. When the ultrasonic stop, let the pressure continue for a few seconds to solidify and shape, so as to form a strong molecular chain, achieve the purpose of welding, welding strength can be close to the strength of raw materials. The quality of ultrasonic plastic welding depends on the amplitude of transducer welding head, applied pressure and welding time. The welding time and welding pressure can be adjusted, and the amplitude is changed by transducer and amplitude. Rod decision. There is an appropriate value for the interaction of these three quantities. When the energy exceeds the appropriate value, the melting amount of the plastic will be large, and the weldment will be easy to deform; if the energy is small, it will not be easy to weld firmly and the applied pressure can not be too large. The optimum pressure is the product of the side length of the welding part and the optimum pressure per 1 mm of the edge.
