Ultrasonic Tube Sealer

The Ultrasonic Tube Sealer is a popular option in the packaging industry today. The process involves placing the plastic tube between a sealing anvil and an ultrasonic horn, which creates intense vibrations that fuse the plastic together.

VTech offers an explosion-proof version of the machine to hermetically seal copper tubes in refrigeration circuits, requiring flammable HC replacement gas. It is a great choice for hazardous environments and meets all safety standards including ATEX and NFPA70 Class I, Division 2.

Easy to Operate

Ultrasonic tube sealers are easy to operate and maintain. They use ultrasound to weld the tube, and their operation is more precise than that of a heating sealing machine. In addition, they are less likely to damage the inside of a tube. Because of this, they can be used with sensitive products such as medicines and cosmetics.

In contrast, a heating sealing machine needs a large amount of energy to generate the heat needed for welding, which can affect the quality of the finished product. This is because the heat generated by the machine is not distributed evenly throughout the tube. Instead, it is ultrasonic tube sealer concentrated on a small area at the end of the tube. The ultrasonic tube sealer, on the other hand, produces a smooth, even seal that does not damage the contents inside the tube.

This semi-automatic model from Rentafill is designed to hermetically seal copper tubes for refrigeration circuits. The sealer is based on sonic technology and can be used in hazardous and non-hazardous environments.

The RTS-15 tube sealer is easy to operate and requires little maintenance. The unit is made of stainless steel and has an independent platform. It is also equipped with a pneumatic trimmer and can print codes on the seals. The device can seal up to 10-15 tubes per minute.

Stable Performance

Unlike the hot air sealers, this machine uses ultrasonic energy to create the weld. The acoustic vibrations create friction and heat at the molecular level. The plastic becomes soft and starts to melt, resulting in a strong bond between the two components. The resulting weld is a tight, secure seam that’s resistant to oxidation. This is a much more reliable process than traditional heat sealing.

In addition, the ultrasonic horn’s welding tool (anvil and sonotrode) stays cold throughout the entire sealing process. This is because the acoustic vibrations convert to frictional heat inside the thermoplastic film. It is important to keep in mind that the weld length with ultrasonic welding is typically a bit shorter than traditional heat sealing.

Ultrasonic sealers can work with a wide range of plastic and laminate tube materials, including LDPE, HDPE, PP, multi-layer and mono-layer with or without EVOH barrier protection. They can also seal aluminum-plastic tubes and composite tubes. This makes them the ideal choice for food, cosmetics and pharmaceutical industries.

Lastly, ultrasonic welders can also hermetically seal copper tubes for refrigeration circuits. This can be done in a single step by crimping, sealing and cutting off charged tubes in under one second. This allows for higher production rates and is a good solution for hazardous environments. It is compatible with both ATEX and NFPA70 Class I, Div. II safety standards.

Long Lifespan

A tube sealing machine with an ultrasonic sealer uses sonic technology to create a strong bond between the plastic layers in your product. The vibrations quickly melt the layers together, making the seal quick and precise. This makes it ideal for sealing small to medium sized tubes in a laboratory or production setting.

In addition to being quick, an ultrasonic tube sealer is also long-lasting. Unlike heat sealers, which can wear down over time due to rough handling or contact with hard products, an ultrasonic welder can be used for years with minimal maintenance. This is because the ultrasonic sealer uses no moving parts, which means that it can be used with a wider range of products and materials.

Ultrasonic technology is also efficient in terms of energy consumption. Depending on your film type and output, you may find that your energy usage is significantly lower with an ultrasonic sealer than with a traditional heat-sealing machine. This is because an ultrasonic sealer uses only a fraction of the power required to run a heat-sealing machine with servo-driven jaws.

The TECH-SONIC explosion proof ultrasonic welder model US-3620TS-EX is designed to hermetically seal the copper tubes of refrigeration circuits in accordance with the NFPA70 Class I, Division II standards. It is the perfect choice for applications ultrasonic tube sealer in both hazardous and non-hazardous environments, and it complies with the ATEX standards (EX Zone 2). It features a stainless steel body, a digital ultrasonic generator, and a fully automated control system that eliminates the need for manual adjustment of amplitude or frequency.

Easy Maintenance

A tube sealer is designed to meet a wide variety of requirements. Its design allows for simple operation and maintenance. It requires no heat applied to the surface of the materials being welded together, and it does not require any consumables. This helps to reduce costs and improve the quality of the finished product.

The nozzle of an ultrasonic tube sealer produces high-frequency vibrations that cause friction between the layers of plastic to melt and bond. This causes a hermetic seal and prevents air from entering the package. It also protects the underlying products from contamination and degradation due to contact with contaminants.

Unlike heat sealing machines, ultrasonic tube sealers do not require an internal heating element. Instead, the weld tool (anvil or sonotrode) is shaped to focus the energy on the area where the welding should take place. This is called “energy focusing.” This is the key to achieving precise welds and accurate dimensions.

TECH-SONIC’s US-3620TS model offers a spectacular solution for a wide array of metal tube sealing applications.

Application

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.

Technology

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.

Maintenance

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.
