Ultrasonic spot welding is where plastics are subjected to binding at certain points without the need of a specific joint design.It is commonly used to apply sturdy structural welding points in multiple parts, such as extruded sheets or plastic parts of complex shapes
【Ultrasonic Welding Principle】
1. Ultrasonic welding machine is the use of ultrasonic generator to convert low current frequency to high frequency AC, then the same frequency of mechanical vibration by ultrasonic transducer
2. Mechanical vibration transmitted to the ultrasonic welding joints by the amplitude modulator, the vibrational energy welding joints received transfer to the workpiece to be welded joint. In the region, the energy through friction converted into heat energy, to melt the plastic
3. After vibration stopped, maintain short-term pressure makes the weldment on artifacts in molecular link way solidification as a whole
【Features】
Ultrasonic spot welding machine can shortens process time, a combination of plastics can be finished through ultrasonic processing within several milliseconds, the process is not only clean, stable and reliable, but also low energy consumption
