Different from heat sealer, ultrasonic tube sealers use ultrasonic technology to enable molecules on the surface of the tubes to be fused together by ultrasonic friction. It combines auto tube loading, position correcting, filling, sealing and cutting. What's more, it makes fast and less space occupied. It is also the perfect choice for cosmetic cream or other cream product tube filling and sealing. Its technology is a perfect solution for cosmetic or other liquid/semi-liquid product tube sealing.
Ultrasonic welding has become a well-accepted method for joining high-volume, relatively small plastic parts. In this process, an ultrasonic generator is used to produce oscillations of one substrate against a stationary second substrate. This, in turn, causes intense frictional heating between the two substrates, which is sufficient to rapidly generate a molten weld zone. With pressure and subsequent cooling, a strong bond can be obtained.
The ultrasonic welding process consists of four phases.
In phase 1, the horn is placed in contact with the substrate, pressure is applied, and vibratory motion is started. Heat generation due to friction melts points of direct contact, and the molten material flows into the joint interface.
In phase 2, the melting rate increases, resulting in increased weld displacement, and the part surfaces fully meet.
In phase 3, steady-state melting occurs, as a constant melt layer thickness is maintained in the weld.
In phase 4, the holding phase, the vibration ceases, maximum displacement is reached, and a high joint strength occurs as the weld cools and solidifies.
Ultrasonic welding is suitable both for welding of plastics and metals. Plastic is a pretty poor conductor of heat and can't dissipate the heat before it changes the state of the plastic from solid to liquid. With a bit of pressure applied, this makes the two parts blend together as if they are a single piece of plastic. Once the ultrasonic signal is stopped, the parts become solid again. This is the magic that creates a clean and strong weld between two parts.
