28Khz Ultrasonic Transducer for Sonotrode for Ultrasonic Elastic Cord Sealing Machine for KN95 Mask
Description:
Ultrasonic transducer is a device that converts electrical energy, mechanical energy or acoustic energy from one form of energy to another, called a transducer, also known as an active transducer. The more mature and reliable one is the piezoelectric effect. A device that realizes the mutual conversion of electrical energy and sound energy, also known as piezoelectric transducer.
The 28Khz ultrasonic transducer produced by QRsonic is suitable for spot welding of plastics, as well as spot welding of KN95 and flat masks.

Way of working:
Due to different processing methods and requirements, the working
modes of ultrasonic transducers can be roughly divided into
continuous work (metal welding) and pulsed work (plastic welding).
Different working modes have different requirements for the
transducer. Generally speaking, continuous operation has almost no
pause time, but the working current is not very large. Pulse
operation is intermittent, with pauses, but the instantaneous
current is large, and the power in both states is very large.
Ultrasonic transducer type and maximum power: There are different
regulations for the nominal power of machines for different
purposes. The same ultrasonic transducer used on different machines
may have different nominal powers. In order to avoid ambiguity, the
customer should specify the structural type of the transducer, such
as column type, inverted horn type, etc., as well as the diameter
and number of piezoelectric ceramic chips.
