28Khz Piezoelectric Ceramic Ultrasonic Welding Transducer

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 packaging 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 equipent. The transducer decide the property of the machine. We can supply transducer, also transducer with horn and booster.

 28Khz Piezoelectric Ceramic Ultrasonic Welding Transducer



What is ultrasonic transducer?

Ultrasonic transducer is a component that utilize the piezoelectricity for actualize electroacoustic conversion. jydsonic ultrasonic cleaning transducer are used where powerful ultrasonic wave must be generated, such as in cleaning equipment and easy to instal. These transducers are mounted into a structure that can be bolted almost anywhere.

Transducer requirements will depend on the application. Many requirements will conflict with one another and will be given different priorities. Hence, no single set of guidelines can encompass all requirements — i.e., there are many different ways to achieve the same objectives.

Analytically, transducer performance can only be predicted in a general way. This is because the properties of piezoelectric ceramics are often highly dependent on the operating conditions including temperature, electrical field strength, static compressive prestress, dynamic stress, number of load cycles, and time. These operating conditions can interact with each other and the effects of these conditions are often nonlinear. Also, many properties of piezoelectric ceramics are orthotropic and can vary among the individual ceramics and also between ceramic lots. Further, the interactions at the various component interfaces (e.g., at threads) may be difficult to characterize and the coefficient of convective heat transfer for air cooling may only be approximately estimated. Hence, much of the design process involves experimental testing.

The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.


• Converter: converters the electrical signal into a mechanical vibration
• Booster: modifies the amplitude of the vibration. It is also used in standard systems to clamp the stack in the press.
• Sonotrode: applies the mechanical vibration to the parts to be welded.

Ultrasonic transducer is the core device that converts electrical energy into mechanical energy (ultrasonic), the piezoelectric ceramic chip adopts imported parts, and can give a strong and stable output. It is made from American aluminum alloy and titanium alloy. The frequency is 15 KHZ ~ 28 KHZ.
