20KHZ NTK Type Ultrasonic Welding Transducer For Ultrasonic plastic welding

Ultrasonic welding can be performed using an ultrasonic. It is known to use plastic to construct containers. In this regard, it is known to create a container by sealing together two layers of plastic. One method for sealing together layers of plastic is through ultrasonic welding. Welding horn.

A welding horn is generally shaped to have a welding edge contoured to the shape of the desired weld. The ultrasonic welding horn further includes a source of vibration which is often reflective. Activating the source initiates vibration which excites the mass of an ultrasonic horn to vibrate At an ultrasonic frequency. Because of equilibrium, the vibrational energy was transferred to the mass of the horn must, in turn, leave the horn in the form of heat, sound waves or otherwise by affecting movement of another object in contact with the horn. Friction transmits horn vibrations to the interface of two parts, heating the surfaces and causing material to flow.

As a result, the melted layers become welded together, forming a seal at the weld.

An ultrasonic transducer is a device that converts electrical ultrasonic energy into ultrasound energy, or sound waves above the normal range of human hearing. While technically a dog whistle is an ultrasonic transducer that converts ultrasonic mechanical energy in the form of air pressure into ultrasonic sound waves, the term is more apt to be used to refer to ultrasonic piezoelectric transducers that convert electrical energy into ultrasound.

Piezoelectric crystals have the property of changing size when a voltage is applied, thus applying an alternating current (AC) across them causes them to oscillate at very high frequencies, thus producing very high ultrasonic frequency sound waves.

The location at which a ultrasonic transducer focuses the ultrasound can be determined by the active ultrasonic transducer area and shape, the ultrasound frequency, and the ultrasonic sound velocity of the propagation medium.
