Ultrasonic welding machines use the ultrasonic vibration to convert the electric energy into mechanical energy and then convey the energy to the plastic surface through the ultrasonic welding mould. The intense friction between molecules and molecules generates heat, which makes the products melt instantly and combine into one body. The processing speed is fast, clean, economical and environmentally friendly.
