Frequently Asked Questions (FAQ)

Why choose Ultrasonic Sealing over Heat Sealing for high-speed card packaging?

Ultrasonic sealing (at 12,000 to 30,000 pcs/hour) uses localized frictional heat, which prevents thermal degradation of the surrounding plastic and the card's internal electronics. It offers immediate bond strength with no warm-up time, significantly increasing throughput and energy efficiency compared to traditional heat sealing.

Can you customize ultrasonic frequencies for different materials?

Yes. As expert manufacturers, we calibrate our machines to operate at 20kHz, 35kHz, or 40kHz depending on the material thickness and desired weld aesthetic. Higher frequencies are typically used for delicate, thin films to prevent piercing.

How does Wentong ensure the reliability of its Custom Ultrasonic Testing Machines?

Every machine undergoes a 48-hour continuous stress test in our Shenzhen factory. We use high-grade piezoelectric transducers and digital generators that monitor amplitude fluctuations in real-time, ensuring consistent performance across global power grids.

What is the maintenance cycle for ultrasonic horns?

With our high-quality titanium and hardened steel alloys, our horns typically last for millions of cycles. We also provide on-site training to teach your team how to inspect for wear and perform simple frequency tuning, ensuring minimal downtime.
