Ultrasonic Tube Sealing Machine

Ultrasonic tube sealers convert electrical energy into mechanical vibrations to join metals. The ultrasonic tube sealing machine process eliminates the use of glue and allows the thermoplastic parts to bond themselves. As a result, ultrasonic tube sealers are the fastest and most reliable way to seal all types of tubes.

The copper tube welding machine system uses a one-step operation to crimp, seal and cut electrically charged copper and aluminum tubes at lightning speed. The ultrasonic tube sealer can seal copper and aluminum tubes up to 12 mm long and is designed to optimize safety, efficiency, and productivity in hazardous environments.

The ultrasonic tube Sealing process is used for high-volume automated production, mainly for sealing copper tubes for refrigerators, air conditioners, and other equipment, and for sealing and cutting copper and aluminum tubes for vacuum devices. Sealing with the ultrasonic tube sealer welding requires no melting, short sealing times, and no fluxes, shielding gases, or fillers. No change in material properties and no contamination during the sealing and cutting process.

XIAOWEI is a quality ultrasonic tube sealing machine manufacturer and supplier, offering a high-performance ultrasonic tube welding machine system. 

Ultrasonic tube sealing machine equipment has stable performance, can be customized for automated production lines, high production efficiency suitable for mass production in factories, suitable for a variety of different materials, different tube diameter, tube thickness material sealing and cutting, a wide range of applications.

XW ultrasonic systems hermetically seal copper and aluminum tubes. A one-step operation crimps, seals and cuts off charged tubes in under one second. Systems are suited to automation for high levels of efficiency and productivity.


1.Ergonomic, light-weight design for operation on the assembly line
2.Patented, quick change tooling with multiple weld surfaces for low cost operation
3.Automatic process monitoring ensures each seal falls within preset quality limits of weld power, time and final height
4.Automatic tube measurement to assure proper placement of tubes within the tooling
5.Weld-to-height mode to compensate for tube material variations
6.Various tube sizes may be sealed in any sequence through automatic setup of weld parameters

Working Principle

The ultrasonic welding process converts electrical energy into mechanical vibrations causing the metals to join. In the ultrasonic stack, the converter transmits the energy through the booster causing the horn to vibrate. The converter is made up of piezoelectric ceramic disks that expand and contract at the same frequency of applied electrical energy. The booster increases or decreases the amplitude of the vibrations to provide the optimum amplitude for the material, size and type of assembly.


XW ultrasonic metal tube sealing systems use a one-step operation to crimp, seal and cut off charged copper and aluminum tubes with lightning speed. The machine hermetically seals copper and aluminum tubes up to 12mm and is designed to optimize safety, efficiency and productivity in hazardous environments. Applications include sealing charged tubes used in refrigerators, air conditioners, bulb temperature sensors and capillary tubes.
