35KHZ Symmetric Ultrasonic Rotary Horn for Radial Acoustic Welding

A rotary ultrasonic assembly mounted in a bearing housing that can be mounted in any orientation. It is available in 20, 35 kHz with bond widths of up to15MM. The bonder is intended for machinery manufacturers and experienced end users who desire to develop their own actuation and tooling solutions. Ultrasonic Sewing Machines operate like a traditional rotary sewing machine but produce soft, smooth seams that are impervious to moisture or fluids.

35KHZ Symmetric Ultrasonic Rotary Horn for Radial Acoustic Welding

An ultrasonic rotary horn has tapered input sections for the conversion of axial acoustic energy into radial acoustic energy. The preferred rotary horn includes a first half having a first radial weld section and a first axial input section for receiving a first axial acoustic energy. The rotary horn further includes a second half coupled to the first half. The second half has a second radial weld section and a second axial input section for receiving a second axial acoustic energy. Each half has a coned section defined by an inner tapered surface and an outer tapered surface such that the halves convert a portion of the first and second axial acoustic energy into radial acoustic energy. Each inner tapered surface forms an inner angle with respect to an axis of the horn and each outer tapered surface forms an outer angle with respect to the axis.

A rotary ultrasonic assembly mounted in a bearing housing that can be mounted in any orientation. It is available in 20, 28,30,35 kHz with bond widths of up to18MM. The bonder is intended for machinery manufacturers and experienced end users who desire to develop their own actuation and tooling solutions.  Ultrasonic Sewing Machines operate like a traditional rotary sewing machine but produce soft, smooth seams that are impervious to moisture or fluids.

Rps-sonic supply high power rotary ultrasonic systems to the packaging, hygiene and specialty converting industries.


While a number of horn configurations have been developed, it is well known that a good way to attain high quality and high speed ultrasonic welds is to use a rotary horn with a rotating anvil. Typically, a rotary horn is cylindrical and rotates around an axis. The input acoustic energy is in the axial direction and the output acoustic energy is in the radial direction. The horn and anvil are essentially two cylinders positioned close to each other, rotating in opposite directions with equal or nonequal tangential velocities. The parts to be bonded pass between these cylindrical surfaces at a linear velocity which usually matches the tangential velocity of these cylindrical surfaces. Matching the tangential velocities of the rotary horn and the anvil with the linear velocity of the parts can minimize the drag between the horn and the parts.


Rotary horns are therefore typically made up of at least an axial input section and a radial weld section. The input section receives the axial acoustic energy, while the weld section applies the converted radial acoustic energy to the target parts. While the above-described conventional rotary horn is acceptable for some applications, certain important difficulties remain. One difficulty relates to the desire to obtain a high level of amplitude uniformity. Amplitude uniformity is effectively a measure of the percent of the weld receiving the same amount of weld energy. Specifically, amplitude uniformity is determined by measuring the maximum displacement of the external surface of the weld section (i.e., the weld “face”) for a given input excitation. The minimum displacement for the same excitation is also measured, and the ratio of the minimum displacement to the maximum displacement represents the amplitude uniformity. Thus, a rotary horn with an amplitude uniformity approaching one hundred percent would produce very uniform output acoustic energy over its entire weld face. High amplitude uniformity results in more predictable welds and ultimately lower manufacturing costs.

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.

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.


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.

We are committed to developing a more stable ultrasonic generator, which minimizes the failure rate of the box and escorts your production process.
