Understanding the strength of ultrasonic welding operations cannot reach the strength of integrated molding, it can only be said to be close to the strength of integrated molding, and the required standards for welding strength must rely on multiple combinations. What are these combinations Plastic material: The result of ABS and ABS fusion is definitely stronger than that of ABS and PC fusion, because the melting point of two different materials will not be the same, and of course, the strength of fusion cannot be the same. Although we are exploring whether ABS and PC can be fused together? Our answer is that it is absolutely possible to weld, but is the strength after welding what we need? That’s not necessarily the case! And from another perspective, what about the situation where ABS melts with nylon, PP, and PE? If the ultrasound HORN instantly emits 150 degrees of thermal energy, although the ABS material has been melted, nylon, PP, and PE are only softened. We will continue to increase the welding parameters. At this point, nylon, PP, and PE have reached the ultrasonic fusion temperature, but the ABS material has been resolved to a different molecular structure!

When ultrasonic vibration is applied to plastic products, the surface of the product is prone to burns, and plastic columns or holes with thinner wall thickness within 1m/m are also prone to cracking. This is an inevitable prerequisite for the operation of ultrasonic plastic welding machines. On the other hand, due to the insufficient output energy of ultrasound waves (such as the extension and HORN upper model), it takes a long time to fuse the vibration friction energy into thermal energy, in order to accumulate thermal energy to compensate for the insufficient output power. This welding method does not achieve vibration friction heat energy in an instant, but relies on welding time to accumulate heat energy. Even if the melting point of plastic products reaches the fusion effect, it will cause the heat energy to stay on the surface of the product for too long, and the accumulated temperature and pressure will also cause burns, breakage, or rupture of the product. At this point, it is necessary to consider factors such as power output (number of segments), fusion time, dynamic pressure, and other coordination factors to overcome this lack of operation.
