Ultrasonic welding system UWP 250

Ultrasonic welding machines



Ultrasonic technologies are set out because of their benefits in different branch industry of series production, short-run production or research work. It is the same for ultrasonic welding. Specific merits of the plastic welding of , non-woven textiles, artificial leather etc. are:


  • care of environment - plastic jointing without sizing materials or chemicals
  • small power spending - ultrasonic machine is not heating during welding
  • cleanness, work without mechanical or chemical rubbish
  • high level of repeatability and the same quality of weld
  • short time of his own welding process
  • small severity of space and small weight of the technological machine


Ultrasonic set for manual welding (further on only “welding set”) is designed for direct welding of plastic materials such as plastic foils, non woven textiles, etc. It is possible to use it for joining other materials by suitable plastic rivets.

Welded materials are placed above each other on a suitable support plate, that they touch at required welding place. On the ultrasonic generator could be set required parameters of joint as the welding
time, output power or overall output. Welding device is activated by the manual switches or by footswitch. After the switch is switching, the pneumatic tool is pressed welding tool (sonotrode) to the top welding part. With intensive ultrasound from the welding tool come to meltingdown and after that to joint of plastic material where they touch. Weld time is determined by switching time switch or set the weld time using the timer control, whichever is less. After joint is complete, the sonotrode for the short time press welding materials together to achieve the required joint strength. Then the sonotrode will return to the resting position.


Because of the large number of existing plastic materials and their shapes is neccessary tested suitability of usage ultrasonic welding tool for concrete aplication. When thinner materials is welded in addition to set duration of weld, may also be needed to reduce output power of ultrasonic generator
