High Power Ultrasonic Ceramic Transducer  transformer for 20khz ultrasonic plastic welding machine 2000W

Ultrasonic waves are transformed into mechanical vibrations through transducers. The characteristics of transducers depend on material selection and manufacturing process. The performance and service life of transducers of the same size and shape are very different. The commonly used high-power ultrasonic transducer is used in ultrasonic plastic welding machine, ultrasonic metal welding machine, various handheld ultrasonic tools, continuous working ultrasonic emulsifier, atomizer, ultrasonic engraving machine and so on. Commonly used products such as 15KHz 20KHz 28KHz 35KHz 40KHz 55KHz 70KHz can also design and produce non-standard transducers according to the special requirements of customers to meet all kinds of needs.

First, a short description of ultrasonics. Ultrasound is the range of sound frequencies just above average human hearing range. Ultrasonic welding typically occurs at frequencies between 50 kHz and 15 kHz.

The ultrasonic wave is created through the use of piezo-electric ceramics which have a special property where they expand or contract when exposed to an electrical current. The ceramics are typically housed in a component called a "transducer". The size and number of ceramics determines the amplitude and power of the ultrasonic waves that can be generated.

For most standard equipment, transducers are a common component to which ultrasonic tools can be attached. The ultrasonic tool is designed to apply a specific amount of ultrasonic energy into a defined area. Depending on the amplitude, frequency, and power applied, the ultrasonic waves can be used to generate heating and weld materials, agitate a  liquid for cleaning, or for inspection

Description:

Ultrasonic Transducer for Welding, Drilling and Polishing High-power ultrasonic drilling machine, welding machine, polishing machine vibrator have small machinery loss, high efficiency electricity and sound transfer, big swing and less heat.

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.

15Khz transducer widely used in high power welding&sealing system.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.

To design and fabricate the transducers according to customers' requirements.
