Fast Welding Speed High Welding Strength by 28Khz Ultrasonic Power Welding Equipment
Description:
Ultrasonic spot welder welding principle is to convert 50/60 Hz current into 20, 28, 35 kHz electric energy through ultrasonic generator. The converted high frequency electrical energy is again converted by the transducer into a mechanical motion of the same frequency, and then the mechanical motion is transmitted to the welding head through a set of amplitude modulator devices that can change the amplitude.
The horn transfers the received vibrational energy to the joint of the workpiece to be welded, in which the vibrational energy is converted into thermal energy by friction to melt the plastic.
The short pressure maintained on the workpiece after the vibration stops causes the two weldments to solidify in a molecularly linked manner. Generally, the welding time is less than 1 second, and the obtained welding strength is comparable to that of the body.
Ultrasound can be used not only to weld hard thermoplastics, but also to fabrics and films. The main components of a set of ultrasonic welding systems include ultrasonic generators, transducer/amplifier/welding head triples, molds and frames.

What are the characteristics of ultrasound?
Our ears can only distinguish sounds with a frequency of 20 to 20,000 Hz. Sound waves with a frequency higher than the human hearing frequency range are one of the categories of sounds. They belong to mechanical waves. Sound waves mean that the human ear can feel a kind of longitudinal wave. The frequency range is 16Hz-20KHz. When the frequency of sound waves is lower than 16Hz, it is called infrasound wave. When it is higher than 20KHz, it is called ultrasonic sound wave. Ultrasonic wave has the following characteristics:
1. Ultrasonic waves can be effectively propagated in media such as gases, liquids, solids, and solid solutions.
2. Ultrasound can transmit very strong energy.
3. Ultrasound produces reflection, interference, superposition and resonance.
4. When ultrasonic waves propagate in a liquid medium, strong impact and cavitation can occur at the interface.
