The SEW US/04 ultrasound sewing machine has been designed and developed using the latest technology (3D CAD, CNC). This modern design sewing machine, is suited to the welding of synthetic fabrics, as an alternative to sewing with thread.
The special feeding system, with adjustable pressure, makes it possible to carry out curvilinear welding jobs.

The ultrasound generator used has a power rating of 1000 Watt, with a frequency of 36 KHz.
All the welding parameters are adjustable:

  • Feeding speed
  • Vibration amplitude
  • Thrust pressure
  • Welding height

Various welding geometry options are available through the simple replacement of the feeding wheel and counterwheel. This makes it possible to obtain imitation stitching in different patterns.

The ultrasound generators of the DIGITAL SE-09 series feature a front panel with backlit display that shows all the programme information and instructions for use.
The new programming system and different functions selection is managed by a rotary selector switch with enter button.
This system makes selection extremely fast and easy. The panel includes some Led indicators to provide additional control functions and a Test button  to start the ultrasound function.
