28khz 800W ultrasonic welding transducer application in spot welding

Parameter

Advantage

Every devise has certain advantages and limitations. The piezoelectric transducers offer several advantages as mentioned below:

1) High frequency response: They offer very high frequency response that means the parameter changing at very high speeds can be sensed easily.

2) High transient response: The piezoelectric transducers can detect the events of microseconds and also give the linear output.

3) High output: They offer high output in the electronic circuit.

4) The piezoelectric transducers are small in size and have rugged construction.

Introduction

Ultrasonic Welding Transducer is the Core components of ultrasonic welding machine

The ultrasonic welding transducer consists of three parts: the transducer ; the amplifier (BOOSTER); the ultrasonic welding horn (also known as SONTRODE).

Transducer is to convert electrical signals into mechanical vibration signals. There are two physical effects that can be used to convert electrical signals into mechanical vibration signals. A: Magnetostrictive effect. B: Reverse effect of piezoelectric effect. Magnetostrictive effect is more commonly used in early ultrasonic applications, and its advantages are large power capacity that can be made; its disadvantages are low conversion efficiency, difficulty in production, and difficulty in mass industrial production. Since the invention of Langevin piezoelectric ceramic transducers, the application of the piezoelectric effect inverse effect has been widely adopted. Piezoelectric ceramic transducers have the advantages of high conversion efficiency and mass production. The disadvantage is that the power capacity of the piezoelectric ceramic transducer is relatively small. Existing ultrasonic machines generally use piezoelectric ceramic transducers. The piezoelectric ceramic transducer is made by sandwiching the piezoelectric ceramic between two metal front and rear load blocks and tightly connected by a screw. The amplitude of a typical transducer output is about 10 μm.
Ultrasonic transducer
The ultrasonic booster is an important part of the ultrasonic vibration system. Its main role in the vibration system is to amplify the mass displacement or velocity of the mechanical vibration, and to concentrate the ultrasonic energy on a small area, that is, to concentrate energy. Also called an ultrasonic gear shifter or an ultrasonic concentrator.

Ultrasonic Welding HORN: The function of the welding head is to make specific plastic parts, which meet the requirements of the shape and processing range of plastic parts.
Ultrasonic welding head

The transducer, booster, and welding horn are all designed to work at half the wavelength of the ultrasonic frequency, so their size and shape must be specially designed; any changes may cause changes in frequency and processing effects. They need to be changed. Professional production. Durability varies according to the material used. Materials suitable for ultrasonic transducers, horns and welding horn are: titanium alloys, aluminum alloys, alloy steels, etc. Because ultrasonic are constantly vibrating at a high frequency of about 28KHZ, the requirements for materials are very high, which is not what ordinary materials can withstand.

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.
