35Khz 300w Ultrasonic Welding Transducer for Spot Plastic Welding Series
Description:
Ultrasonic waves convert high frequency electrical energy into
mechanical vibration through a transducer. The characteristics of
the transducer depend on the material selection and manufacturing
process. The performance and service life of the ultrasonic
transducer of the same size are very different. Commonly used
high-power ultrasonic transducers are used in ultrasonic plastic
welding machines, ultrasonic metal welding machines, various
hand-held ultrasonic tools, ultrasonic emulsifier homogenizers,
atomizers, ultrasonic engraving machines, etc.
Commonly used 15KHz 20KHz 28KHz 35KHz 40KHz 55KHz 70KHz and other
products We can also design and manufacture non-standard ultrasonic
transducers according to customer's special requirements to meet
various needs.

Why is the wavelength of the sound wave measured at the resonant state of the transducer?
Resonance is conditional. For tube resonance, it is generally 1/4
wavelength resonance. The calculation formula is: 1/4 wavelength of
sound wave = length of tube + effective length of tube diameter
conversion; when resonance occurs, it can be used Calculate the
wavelength of the tube and the diameter of the tube, and calculate
the speed of sound (frequency multiplied by wavelength = speed of
sound); if the wavelength is not calculated without resonance, the
speed of sound cannot be calculated; whether the measurement system
is in resonance or not is whether the sound energy is measured. At
the maximum, the method is to use frequency scanning. When the
sound energy output is maximum, the output frequency is recorded
and then calculated. For the resonance measurement of the tube
resonance, there is a defect, that is, the effective length of the
diameter conversion; usually, the standing wave method for
measuring the sound velocity is Measure adjacent peaks or nodes
(half wavelength) of standing waves.
