15KHZ HIGH POWER Ultrasonic Vibration Transducer Large amplitude
Ultrasonic welding is an industrial technique through which a very high-frequency ultrasonic acoustical vibrations are applied to the work pieces locally and which are being confined together under the influence of high pressure in order to develop a solid-state weld, mostly used for plastics. In other words, it is the joining or altering of thermoplastics via heat which is generated from high-frequency mechanical motion. Electric energy of high frequency is converted into mechanical motion of the same high-frequency to attain welding process. This mechanical motion along with the force which is applied generates frictional heat at the plastic components’ joining surfaces. This will enable the plastic material to melt and form a molecular bond amongst the parts.
Ultrasonic Welding Process
The ultrasonic welder machine will comprise of components such as – Transducer, Sonotrode and Anvil. The complete welding mechanism will include the following steps:
A stationary clamping force is put exactly perpendicular to the interface in between the work pieces.
Then the contacting sonotrode of the welder oscillates parallel to the interface.
This coalesced effect of stationary and oscillating force generates deformation which furthers welding.

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.
High efficiency: high mechanical quality factors and high efficiency of electroacoustic conversion at resonant frequency points.
Large amplitude: the structure of the computer optimized design, the ratio of vibration and speed is high, and the amplitude of the front cover plate is large.
Big power: under the action of the pre-stressed screw, the energy of the piezoelectric ceramic is exerted to the maximum extent.
Good heat resistance: small resonant impedance, small calorific value, wide range of use temperature. High reliability and long life.
