20khz Ultrasonic Piezoelectric Transducer For Mask Making Machine

A device that converts electrical energy, mechanical energy, or acoustic energy from one form of energy to another is called a transducer, or active sensor.

20khz Ultrasonic Piezoelectric Transducer For Mask Making Machine


Description:

Ultrasonic transducers are piezoelectric ceramics that resonate at ultrasonic frequencies. The piezoelectric effect of the material converts the electrical signal into mechanical vibration. Ultrasonic transducer is an energy conversion that converts electrical signal into mechanical vibration. It is an energy conversion device. Its function is to convert the input power into mechanical power (ie ultrasonic) and then transmit it. It will also consume energy itself, but it consumes very little energy.

Competitive advantages

1. Our transducer is made of imported titanium alloy and is made with advanced processing technology.

2. Our transducers are assembled and debugged by teachers with more than 30 years of installation experience, and the assembly effect is excellent, which has now become the standard of the ultrasound industry.

3. The consistency of the parameters of the transducer is very high, which provides convenience for customers to match the ultrasonic generator.

4. The impedance is very small, less than 7 ohms, greatly reducing the heat and loss of the transducer.

5. The output amplitude is large, greater than or equal to 10 microns.

6. The energy conversion rate is greater than 95%.

7. The testing process is very rigorous. For the transducer, the aging time is at least one week, so as to ensure the stability of the transducer parameters.

8. One by one testing to ensure that each transducer performance are excellent.


Application

Ultrasonic transducer is widely used.

1. Application industry: agriculture, transportation, living, medical and military.

2. Functions realized: ultrasonic processing, ultrasonic cleaning, ultrasonic detection, detection, monitoring, telemetry, remote control, etc.;

3. Working environment: liquids, gases, organisms, etc.;

4. Nature: power ultrasound, detection ultrasound, ultrasound imaging, etc. .


Common problem 

The transducer gets hot

Reason: 

1.Heat transfer. The workpiece to be welded will generate heat or the ultrasonically processed material will generate heat, or the mold (tool head) and horn will heat up after a long time of operation. These heat will be transferred to the transducer.

2.The power loss of the transducer itself. Since the energy conversion efficiency cannot be 100%, the part of the energy lost must be converted into heat.

3.The customer failed to match the transducer and drive power to the best working state during use. The heat caused by this is very large and uncontrollable, which will have serious consequences.

Countermeasur

1. When using a transducer, a small fan needs to be added to dissipate the heat of the piezoelectric ceramic parts.

2. It is recommended to match and purchase the entire 20kHz ultrasound system. Please do not purchase separately to prevent the transducer and sensor from matching and causing the transducer to heat up.


How to choose frequency

The higher the frequency, the smaller the amplitude. Therefore, high-frequency transducers are used for welding small and precise plastic parts.

In addition to providing 20kHz transducers, we also provide 15kH and 30khz transducers. 20kHz and 15kH transducers are used for welding large and complex plastic parts, currently mainly used in mask machines, and 35kHz transducers are mainly used in ear strap welding
