Ultrasonic plastic welding is based on the rapid vibration of ultrasonic waves, sealing two thermoplastic materials in sub-second time. Under the pressure of high-frequency sound waves, the entire part connection process can be welded in less than 0.2 second.
The high-frequency vibration of the ultrasonic wave is transmitted to the surface in direct contact with the plastic part. Because the boundary of the welding area has a large acoustic resistance, high temperature will be generated in a short time. Thermoplastic is a very poor heat conductor. It is difficult to transfer its own heat before changing the plastic state from solid to liquid. When pressure is applied, the two parts blend together as if they were a whole. Once the ultrasonic signal stops, the part will harden again. After welding, a clean and firm weld is formed between the two parts. The strength of the weld is close to the strength of the raw material formed in the weld.
Advantages and speed of ultrasonic plastic welding: One of the advantages of ultrasonic plastic welding is high speed, and the welding time is about 1 to 3 seconds. High strength: Ultrasonic plastic welding can withstand sufficient tension. The welding time should be different depending on the welding material, and it should be controlled according to the material. The effect of ultrasonic plastic welding is very good: ultrasonic plastic welding has an efficient and excellent welding effect. It is sonic welding, and the plastic parts will not burn and turn black during welding. Low welding cost: Ultrasonic plastic welding does not require adhesives, solvents, adhesives, mechanical fasteners, less labor, and low cost.
