WHAT is ultrasonic assembly?The basic principle of ultrasonic assembly is the conversion of standard 50/60 Hz power to 15 kHz, 20 kHz or 40 kHz. This electrical energy travels through a piezoelectric converter.The converter, typically lead zirconate titanate, expands and contracts at the same freque
In the process of practical consumption, not all plastic materials can stop welding. Plastics that can be welded by ultrasonic wave belong to thermoplastics. As long as thermoplastics with the same or similar molecular structure can stop welding and chemical separation between molecules on the welding surface, the closer the parent material is, the better the welding effect. The better the fruit. The following figure is a comparison of welding compatibility of some common plastics. We also need to think about the factors that affect the quality of welding to get better welding results. When stopping welding, pressure, time and heat absorption (melting amount) are the three elements to ensure welding quality.
Tesla has applied a specific application in ultrasonic welding technology to its battery system. Wire Bonding has made the application of ultrasonic welding technology in the field of power battery group connection more and more discussed. The application of ultrasonic welding on power batteries
I. OverviewPPS (polyphenylene sulfide) is a semi-crystalline thermoplastic with a steep melting curve and a high melting temperature (285 ° C, 545 ° F), and its pure PPS is not suitable for ultrasonic welding. However, after the addition of glass fiber and other fillers, the rigidity of the PPS mixt
Amplitude A, static pressure F and welding time t, in addition to the choice of ultrasonic power and the interaction between the parameters. In ultrasonic welding, spot welding is the most common application. The following is an example of spot welding to discuss the influence of various parameters
