Product Description

28Khz ultrasonic converter for Pyramid Nylon Teabag Packing Machine


ltrasonic Converters and Ultrasonic Transducers are one in the same. There is one Ultrasonic OEM, Dukane Corporation, that uses the term Transducer. All of the other ultrasonic OEM manufactures such as Branson, Sonics and Materials, Rinco, Telesonics and Herrmann refer to these as Converters or Konverters.


To convert electrical ultrasonic energy of the generator to mechanical oscillation, ultrasonic converters are needed. Our ultrasonic converters are produced inhouse, on high-quality, fully automatic CNC lathes. The ultrasonic converters consist of mechanical components and polarized ceramic discs. Created from high-quality metal alloys, eg stainless steels or titanium. For our titanium alloys, we can prove the suitability for aviation and space technology with certificates and test reports. We offer ultrasonic converters from 20 to 90 kHz, usable for a wide range of applications, for example:

  • Ultrasonic welding
  • Ultrasonic cutting
  • Ultrasonic sieving
  • Ultrasonic cleaning
  • Ultrasonic soldering
  • Ultrasonic atomizing
  • Ultrasonic turning
Technical Data  
Feasible performance: Up to 4000 Watt
Frequencies: 20 - 70 kHz

28Khz transducer widely used in ultrasonic welding machine and ultrasonic hand-held welding gun. And you can always see 28Khz ultrasonic parts in auto, non-woven and packing area. Piezoelectric transducer is the electric charge that accumulates in certain solid materials in response to applied mechanical stress. It is key point of all ultrasonic equipment.The transducer decide the property of the machine.We can supply transducer, also transducer with house and booster.r.



1. The piezoelectric ceramic chip adopts imported parts, and can give a strong and stable output.
2. High efficiency, high mechanical quality factor, obtaining high electric-acoustic conversion efficiency work at the resonance frequency points.
3. Large amplitude: optimization design by computer , vibration speed ratio is high .
4. Large power,Under the action of prestressed screw, the energy of the piezoelectric ceramic to get maximum play;
5. Good heat resistance, small harmonic impedance, low calorific value, using temperature range is wide.



ltrasonic sealing pyramid tea bag packing machine is a economic type. It adopts 4 heads electronic scales measurement methods, can pack different tea, including tea leaf, herbs, flower, fruit tea in to pyramid tea bag or flat tea bag, feeding by vibration, so have a wonderful precision, can be controlled is ±0.2g. Cut off by ultrasound makes the angle very evidently and pretty. It also can keep the tea with complete shape.
