Ultrasonic Tube Sealer

Ultrasonic Tube Sealer

An ultrasonic tube sealer uses vibrations to melt and fuse plastic layers around a tube. It is a fast, precise, and efficient process.

This report focuses on the growth of the Ultrasonic Tube Sealing Machine market and its manufacturers. It covers global market size and shares, segmentation, product development, and key regions.


An Ultrasonic Plastic Tube Sealing Machine is a type of equipment used to seal plastic tubes using ultrasonic energy. It uses high-frequency vibrations to melt and bond the layers of the tube together, creating a strong and leak-proof seal. It is ideal for packaging products such as cosmetics, pharmaceuticals, and food.

The acoustic vibrations generated by the sonotrode and anvil create frictional heat within the thermoplastic film to seal it. This localized conversion of vibrations to frictional heat is the basis for short sealing times between 100 and 200 milliseconds. In addition, it requires little or no energy for cooling, reducing materials usage and production costs.

Another advantage of ultrasonic sealers is that they do not require custom-sized parts like VFFS machines. This allows them to work with a larger range of tube sizes and shapes. Additionally, they can be used to seal through product ultrasonic tube sealer contamination in the sealing area. However, they are slower than a hot air sealer.

This semi-automatic ultrasonic metal tube sealer and trimmer has two processes, sealing and cutting. It can seal plastic and laminate tubes with date/lot embossing and trimming to create professional looking sealed products. It is easy to use, simple to maintain and requires a standard 10amp power point. It is suitable for both hazardous and non-hazardous environments and conforms to ATEX and NFPA70 Class I, Division 2.


With this technology, a plastic tube is placed between a stationary anvil and a vibrating ultrasonic horn. The horn emits high-frequency vibrations that cause the materials to frictionally melt together, sealing the tube. The process is fast, precise and efficient. This technology is widely used in the packaging industry for various products, including cosmetics, pharmaceuticals and food.

The welding process with an ultrasonic machine is a much more precise and controlled than the heating-type machines. For the process to work, the ultrasonic vibrations must be focused (energy focusing). This is achieved by either the geometry of the weld area or by the weld tool (sonotrodes or anvil). Energy focuses on the point at which the welding should take place and then converts to friction heat. This allows for very short welding times of 100 to 200 milliseconds.

Compared to the heating sealer, ultrasonic machines offer a number of advantages, including lower production costs, no need for sealing molds and tube holders, faster changeover, and better reliability. Moreover, they are easier to test and repair. However, the heating sealer requires special tools and can be more expensive.

Ultrasonic plastic tube sealing machines can be easily used for a wide range of tube sizes and types, including LDPE, HDPE, PP, and mono layer or multi-layer with or without EVOH barrier protection. It also works well with composite and aluminum-plastic tubes.


Unlike heat sealing, ultrasonic welding does not require heating the materials to be welded. Rather, the energy generated by the acoustic vibrations is used to weld the materials at the molecular level inside the surface, which results in stronger welds with faster cycle times and greater reliability. This is why ultrasonic welding is vital to numerous industries.

The VTech US-3620TS is a heavy duty 20Khz ultrasonic welder designed to hermetically seal copper tubes in refrigeration circuits in a single step, requiring minimal maintenance. This unit can be utilized in hazardous and non-hazardous environments and complies with ATEX and NFPA70 Class I, Div. II safety standards. It features a failure tolerant weld software called AUTOSET.

The acoustic vibration of an ultrasonic tube sealer generates friction heat which melts the plastic layers and bonds them together, creating a tight and leak-proof weld. This method eliminates the need for additional adhesives and lowers production costs. It can also be used to weld dissimilar materials, and has a low reject rate of less than 1%. This technology is easy to use and requires minimal maintenance.


This is a heavy duty 20Khz ultrasonic welder, specifically designed to hermetically seal copper tubes used in refrigerator and air conditioner coils. The unit is explosion proof and meets ATEX and NFPA70 Class 1, Division 2 certification, providing a safe alternative to brazing and welding in hazardous environments. The system also reduces maintenance costs and cycle times while delivering exceptional weld quality.

The iPharmachine Ultrasonic Tube Sealer Machine uses ultrasonic vibrations to generate heat ultrasonic tube sealer at a molecular level inside the plastic itself. This enables the film layers to melt and bond together, creating a strong leak-proof seal. It also requires less energy than other methods of sealing and is environmentally friendly. It is available in a variety of models, from hot-air and impulse to hot-jaw sealing options.

This compact unit can be operated by a single operator and is easy to clean and maintain. It can seal any plastic or laminate tube material up to 57mm in diameter and is compatible with all standard 10amp power points. It can be supplied with a special tube holding puck to ensure the tubes remain straight during the sealing process and can include a number/letter set for batch stamping of a unique ID onto each sealed tube. This is a perfect addition to any production line or for R&D and quality control.
