20Khz Ultrasonic Waterproof Welding Equipment for Cap Welding And Sealing

Ultrasonic booster is an important part of the ultrasonic vibration system. Its main function in the vibration system is to amplify the mass displacement or velocity of the mechanical vibration, and concentrate the ultrasonic energy on a small area, that is, the energy is collected. Also known as ultrasonic shift levers or ultrasonic concentrators.
Application :
  • CD20
  • Rps-sonic
  • CD20

20Khz Ultrasonic Waterproof  Welding Equipment for Cap Welding And Sealing 

The welding principle of the ultrasonic plastic bottle cap welding machine:

     The plastic cover box ultrasonic welding machine generates a 15KHZ (or 20KHZ) high-voltage high-frequency signal by an ultrasonic generator, and then converts it into the mechanical vibration energy of the same frequency through the piezoelectric inverse effect of the ultrasonic transducer, and acts on it in the form of audio longitudinal wave Plastic products on the workpiece. The friction of the welding joint causes heat generation on the surface of the workpiece. When the temperature rises to the melting point of the plastic workpiece itself, the interface of the workpiece melts rapidly, and then fills the gap between the interfaces. When the vibration stops, the workpiece is cooled and shaped under a certain pressure at the same time. Perfect welding. Plastic welding is the welding of the main body and the main body, and the welding process of welding, embedding, forming, riveting, and cutting can be achieved by using a special welding mold.

    Features of ultrasonic standard plastic wine bottle cap welding machine:

1. Ultrasonic PP plastic bottle cap box welding machine can choose the original imported ultrasonic transducer and ultrasonic generator from Japan, the United States, Germany, and Taiwan, and the quality is reliable;

2. Desktop ultrasonic plastic bottle cap shell welding machine adopts linear guide bearing, precision fine-tuning device, and excellent performance;

3. The ultrasonic food plastic bottle cap welding machine is an electric lifting body, and uses a gear up and down design, which is easy and convenient to operate and has high strength;

4. The ultrasonic plastic box shell welding machine is a digital adjustable pressure trigger system, and the trigger mode adjustment technology is the world's leading;

5, 2600W ultrasonic plastic anti-counterfeiting bottle cap welding machine is designed with IC control loop, automatic frequency tracking, overload protection device, stable quality;

6. Ultrasonic PE plastic box welding machine is designed with anti-backward-back and coaxial direct pressure design. The pressure is balanced and the welding precision is improved;

7. The surface of the ultrasonic bottle cap and box welding machine is well formed, without damage or deformation, no scratches and glue residue;

8. The ultrasonic ABS plastic box welding machine is formed by gravity casting. It adopts a large base and a square column with high welding precision. It has the most advanced international welding modes of time welding, deep welding and collapse welding.

1. What’s the warranty of your transducer and equipment.

Our warranty is one year for both transducer and equipment, but we can supply you Components free even out of warranty.


2. What’s frequency transducer you supply?

We can supply transducer from 15Khz to 70Khz depending on your requirements or application.


3. What’s the using life of your transducer?

Under correct working environment, our transducer can work 5~10 years


4. What’s the using life of your generator?

Under correct working environment, our generator can work 8~10 years


5. Does your products exported before?

Yes, our transducer exported to USA,south America, EUROPE, Middle East, and Russia for many years.


6. Do you supply sample for test?

Yes, you can order on sample from our company first , we will return you the sample cost when you order in the future.


7. Do you supply OEM work?

Yes, welcome to ask for OEM cooperation , we have OEM produced for USA and German customer for many years, also hope to get more OEM order to enlarge our business.


8. how to customize transducer ?

For two ways for customize transducer, first way, you supply me sample , I will customize depending on your sample. Second, you give us all parameter and drawing , we can customize depending on your information.


9. Can you generator connect to PC, PLC or internet .

Yes, we have different version generator, it can connect to PC. PLC, even internet.Also the price different.


10. What we can get if the transducer/equipment broken during the warranty?

All our transducer and generator tested at least 48 hours before shipment , so we have confidence to our equipment. Of course, We will send you new transducer/ equipment if it broken in the warranty. At the same time, we need to find the problem , why it broken so fast.

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.
