Highwing Mold introduces its latest 28kHz high‑frequency automatic frequency chasing ultrasonic welding machine. Designed for small, high‑precision components, this unit combines real‑time frequency tracking with rugged mechanical construction. For manufacturers seeking a reliable sonic welder for plastic, the device delivers welding stability with measurable parameters – 1200W power, 28kHz operating frequency, and a flat welding area of approximately 60mm.

​The Pedal Sealing Machine is a foot-operated impulse sealer that leverages advanced electrical pulse technology to reduce sealing time from 2–4 seconds down to just 0.2 seconds.

The automatic frequency tracking ultrasonic welding machine is an industrial equipment that integrates automatic frequency tracking, touch screen control and high-precision welding. The fuselage adopts a suspended integrated electric box design, which takes up less space and is easy to install. It has a built-in acoustic impedance feedback circuit to ensure stable and reliable welding. It is suitable for spot welding, sealing, wire welding and other scenarios of plastic parts. It is an ideal production tool for e-cigarettes, wearable devices, medical supplies and other industries.

The foot sealing machine uses electrical pulse technology to shorten the original working time from 2-4 seconds to 0.2 seconds. It is a kind of low investment, high efficiency, long sealing length and simple operation.

Sealer is the container with the product to seal the machine, after the product into the packaging container, in order to make the product to be sealed and preserved, to maintain product quality, to avoid product loss, need to seal the container, this operation is completed by the sealer.
