Product Description

 Description:

The ultrasonic transducer comprises a central piezoelectric ceramic element, front and rear metal cover plates, prestressed screws, electrode sheets, and insulating tubes. This type of sandwich transducer, also known as a bolt-fastened transducer, generates stable ultrasonic waves even when the load varies, making it the primary and most fundamental method for obtaining a power ultrasonic drive source.
Depending on different designs, the shape of the ultrasonic transducer mainly includes column type (where the diameters of the front and rear metal cover plates are the same), horn type (where the diameter of the front cover plate is gradually reduced in an arc shape), and column type with a section in the middle.

Core component:
Piezoelectric ceramics are typically classified into two categories: "soft" and "hard." Hard piezoelectric ceramics are specifically designed for power supply applications due to their ability to withstand high mechanical stress and deliver strong, consistent performance under demanding conditions.
Among hard piezoelectric ceramics, there are two primary types, commonly known as PZT-4 and PZT-8. PZT stands for lead zirconate titanate, a material that forms the basis of these ceramics, known for their excellent piezoelectric properties.
PZT-8 piezoelectric ceramics are particularly notable for their superior characteristics. They have a higher quality factor (QM), which means they can generate more power with less energy loss, making them highly efficient. Additionally, PZT-8 ceramics can operate safely at higher temperatures due to their elevated Curie temperature, ensuring reliability in high-temperature environments. Furthermore, PZT-8 ceramics exhibit lower dielectric loss (Tangδ), which reduces energy dissipation during operation, enhancing overall performance and durability.
These features make PZT-8 ceramics ideal for high-power applications such as ultrasonic transducers, sonar systems, and industrial machinery, where both efficiency and stability under extreme conditions are crucial.

Transducer production core step:
In ultrasonic transducer manufacturing, a static compressive prestress is essential because piezoceramics are weak in tension. This prestress ensures that the piezoceramics do not experience tensile stress during ultrasonic vibration, which could damage them. Additionally, it guarantees good contact at the piezoceramic interfaces, minimizing acoustic wave loss. The prestress must be strong enough to prevent both ultrasonic tensile stress and lateral slippage of the piezoceramics.
As the prestress increases, the impedance and frequency of the piezoelectric ceramic become more stable. A higher prestress can reduce the transducer's impedance, but excessive prestress is not ideal, as too much can negatively affect performance. Therefore, finding the optimal level of prestress is critical for producing high-quality ultrasonic transducers.

Applied Range:
Ultrasonic transducer,ultrasonic generator and ultrasonic horn constitute a whole ultrasonic system,
which can be widely used to do welding in various kinds of industries.
Applied Industries: automobile industry, electric industry, medical industry, household appliance industry, non woven fabric
clothing, packing, office supplies, toys, etc.
Applied Machines: Ultrasonic cleaner,Beauty set,welding machines,cutting machines,Medical scalpel and tartar clear.


Competitive Advantage:
1. Titanium, aluminum, steel materials of horn optional.
2. Once assembled, the transducers are aged before testing and final assembly. The properties of piezoelectric materials can change with time and pressure, so a bit of time on the shelf prior to testing will identify nonconforming material.
3. One by one testing to ensure that each transducer performance are excellent.
4. In good heat resistance, can be used in a wide range of temperature with long life and high reliability.
5. Good stability, low heat
6. Good consistency of frequency and static capacity
7. Provide customized service
8. One year warranty
