First, the ultrasonic welding machine output power of choice:
Ultrasonic output power of the size, with the diameter and thickness of piezoelectric ceramics, material, design process decisions, but the transducer shape, the maximum power will be shaped. Measuring the size of the output energy is a complex process, not the greater the transducer, the circuit using more power tube, the greater the output energy, it requires a very complex amplitude measuring instrument to accurately measure its amplitude.
Second, the ultrasonic welding machine workpiece material requirements:
Ultrasonic welding machine to be welded to the workpiece material is required, not all of the materials can be welded, some people think that any material can be welded, this understanding is wrong. Some different materials can be a good direct welding, some basic phase melting, some are not melting. The melting point is the same between the same material, from the principle that can be welded, but when the melting point of the workpiece to be greater than 350 ℃, not suitable for ultrasonic welding. Because the ultrasound is the moment to melt the workpiece molecules to determine the basis is within 3 seconds, can not be a good welding, it should choose other welding process. Such as hot plate welding. ABS material is generally the most easily welded, nylon is the most difficult welding.
