Product Description

 Description:

The ultrasonic transducer is a critical component in ultrasonic systems, composed of several key elements that work together to convert electrical energy into mechanical vibrations. At its core is the piezoelectric ceramic element, which is responsible for generating ultrasonic waves when subjected to an electric field. This central element is sandwiched between front and rear metal cover plates that help transmit the vibrations effectively. The assembly is held together by prestressed screws, which apply the necessary compression to maintain structural integrity and enhance the transducer's performance under varying load conditions. Electrode sheets are integrated into the design to ensure efficient electrical connection, while insulating tubes provide protection and ensure electrical insulation between components.
The design of ultrasonic transducers can vary to meet specific application needs. The most common shapes include:
Column Type: In this design, the diameters of the front and rear metal cover plates are identical, providing a balanced structure that is ideal for general-purpose ultrasonic applications.
Horn Type: This design features a gradually reduced diameter of the front cover plate, typically in an arc shape. The horn-type transducer is designed to amplify the ultrasonic vibrations, making it suitable for applications requiring higher intensity ultrasonic waves, such as precision welding or cutting.

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:
Because piezoceramics are weak in tension, a static compressive prestress must be applied to prevent the piezoceramics from experiencing tensile stresses when the transducer vibrates ultrasonically. The prestress also assures that the piezoceramic interfaces make good contact so that the acoustic waves are transmitted well with minimum loss. The compressive prestress must be sufficient to prevent the piezoceramics from ever experiencing any ultrasonic tensile stress and prevent any lateral piezoceramic slippage. In the manufacturing process of ultrasonic transducers, the size of prestressing plays a decisive role in quality.
The piezoelectric ceramic impedance and frequency will stabilize with the prestress's increase. A larger prestress can reduce the impedance of the transducer. If the piezoelectric ceramic is not sufficiently clamped, the transducer impedance will become larger. But not the largest is the best.

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
