Advantages of ultrasonic plastic welding:
1. High strength: Ultrasonic welding can withstand enough tension, and the strength of the welding can be properly adjusted according to the welding material.
2. Fast: One of the advantages of ultrasonic welding is the high speed, and the welding time is roughly between 1 and 3 seconds.
3. Good welding effect: Ultrasonic welding has excellent welding effect. Because it is sonic welding, plastic parts will not be burned and blackened during the welding process.
4. Lower welding cost: Ultrasonic welding does not require glue, solvent, adhesive, mechanical fasteners, less labor and lower cost.
It is a high frequency vibration of 15 to 70 kHz applied to two plastic parts, and the high frequency vibration can be changed according to the specific welding application. This vibration is created by using piezoelectric ceramics in the transducer, which convert electrical signals into mechanical motion. The transducer produces vertical vibrations, which are then transmitted through the horn and subsequent ultrasonic tool head. Ultrasonic high-frequency vibration creates periodic strain in the weld area, which generates heat, which melts and welds the two plastic parts in a partial area. Since ultrasonic vibrations act on the entire welding surface, energy directors are often added to control melting and reduce the amplitude needed to achieve the weld.
In plastic welding, ultrasonic horns are usually designed to contact the part directly above the welding area so that vibrations can propagate through the upper part to the welding area.
