What materials can be welded with ultrasonic transducers?

Ultrasonic welding works best with thermoplastics, non-ferrous metals, and some composite materials. Common applications include plastic parts, thin metal sheets, and wire splicing. Material compatibility depends on acoustic properties and melting characteristics.

How do I choose the right frequency for welding applications?

Lower frequencies (15-20 kHz) are ideal for larger parts and thicker materials, while higher frequencies (40-70 kHz) work better for small, precision parts. The choice depends on part size, material thickness, and required weld strength.

What factors affect ultrasonic welding quality?

Key factors include frequency selection, amplitude control, welding time, applied pressure, part design, and material properties. Our transducers provide precise control over these parameters for consistent weld quality.

Do you provide technical support for welding applications?

Yes, we offer comprehensive technical support including application analysis, parameter optimization, troubleshooting, and training. Our engineers can help optimize your welding process for best results.

What safety considerations are important for ultrasonic welding?

Safety measures include proper operator training, hearing protection, equipment grounding, regular maintenance, and following safety protocols. Our transducers include safety features and we provide detailed safety guidelines.
