20Khz 1000W Ultrasonic Welding Equipment for Lid 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 1000W Ultrasonic Welding Equipment for Lid Welding And Sealing 

Principle of 20Khz 1000W Ultrasonic Welding Equipment for Lid Welding And Sealing :

The plastic bottle cap welding machine converts the current 50/60Hz electric frequency into 20KHz or 40KHz high-frequency electric energy through a transistor function device, and supplies it to the converter. The converter converts electrical energy into mechanical vibration energy for ultrasonic, and the voltage regulator is responsible for transmitting the converted mechanical energy to the welding horn of the ultrasonic welding machine. The welding horn is an acoustic device that directly transmits mechanical vibration energy to the product to be pressed. The vibration is transmitted to the bonding surface through the welding work piece. The vibration and friction generate heat to melt the plastic. The vibration will stop when the molten material reaches its interface. The short-term holding pressure can make the melt produce a strong molecular bond when the adhesive surface is solidified. The entire cycle is usually completed in less than a second, but the welding strength is close to that of a connected material.

Features of Ultrasonic Welding Machine for Plastic Bottle Caps:

1. According to the requirements of bottle cap products, the driving mode can be pneumatic, hydraulic or servo motor drive;

2. Japanese technology piezoelectric ceramic transducer, strong and stable output;

3. Frequency automatic compensation circuit, the whole machine is formed by gravity casting, with high precision;

4. Adopting the horizontal adjustable structure of the welding horn, it is convenient to adjust the mold, stable in use, and high in welding efficiency;

5. The appearance of the bottle cap welding machine has good overall flow linearity, and the surface is sprayed with plastic and is corrosion-resistant;

Application of plastic bottle cap ultrasonic welding machine:

Plastic bottle cap ultrasonic welding machine is mainly suitable for the welding of various round plastic bottle caps such as wine bottle caps, cosmetic caps, beverage bottle caps, food bottle caps, etc.; generally applicable to PP, PE, ABS, AS, PC, POM, PVC And PET material products.

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.
