15khz Ultrasonic Vibration Transducer , Large Amplitude Ultrasonic Transducer For Welding

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.

Naming method:

T - Transducer

50 - The outside diameter for piezoceramic ring (mm)

20 - The frequency of the transducer

4 - The number for piezoceramic ring,

D - The type of transducer D means Chinese type,B-Branson type,Z-NTK type.

PARAMETER

Description:

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.

Advantage

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.

sale the right products instead of the expensive one

Rps-sonic, consisted with a couple of young people who love ultrasonic very much.The founding members of RPS-SONIC have an average degree of Bachelor's degree or above. They have been in the ultrasonic industry for more than 5 years and have rich experience in ultrasound. The company's business philosophy is: Do not blindly promote any product, find the right product for the customer. So before each order, we will confirm all the details, including application details, equipment conditions, equipment specific information.

And we have the Professional import and export company， HangZhou LanBen Trade Co., Ltd, can export to any country wordwide.

Before year 2012, we only sale second branson / dukane / rinco / herrman/telsonic welding equipment , during these twenty year develop, we find, more and more people have problem with the core part of ultrasonic welding equipment -generator and transducer, so we decided to start our business of transducer and generator of our own transducer and generator. Many of the end user meet the transducer problem, they don’t know why transducer broken, and changing the expensive transducer one by one. Actually, one branson /dukane /rinco transducer can use 10~30 year, even the cheapest transducer can use about 5 years. So there must some reasons if your transducer broken in one year. That’s why we want build Rps-sonic, we need to help more end user to know more about transducer , to use ultrasonic equipment better, to save cost when meet problem.

The same to generator, Unreasonable operation may shorter the use-life of ultrasonic generator. So we have to make technical inquiry before operate ultrasonic welding machine. The key point of ultrasonic machine is resonance, only keep every part in resonance can make the system in best work environment.

Till now , we still have a lot of Branson /dukane/ rinco/ herrman telsonic welding machine, so that we can confirm every transducer/generator we made can matching to the original machine.

Of course we can make the transducer/generator replace for Branson /dukane/ rinco/ herrman telsonic welding machine, we can also make transducer/generator for any application of your ultrasonic equipment. We supply OEM service for oversea customers, we already have OEM customer in USA and German.

If you have any problem in ultrasonic area, welcome contact Rps-sonic.
