Welding

PFAFF 8310​

Ultrasonic welding machines of the Seamsonic series combine all the physical advantages of ultrasonic welding with the whole range of technological sewing experience. On the PFAFF 8310 the workpiece is held between the sonotrode and the anvil wheel and welded continuously under pressure. When welding continuously by the ultrasonic method, the material to be welded will be subjected to rapid changing pressure vibrations. The heat develops because of molecular vibrations beneath the material surface, for thin materials within the immediate vicinity of the actual weld.

Ultrasonic welding with the Seamsonic is a modern, innovative and economic alternative and complementary to conventional sewing technology. If assembling of laminates, clothing fabrics with high share of polymer and technical nonwovens is required and in particular to get, the use of the Seamsonic is the first choice.

Features

  • All parameters controlled electronically (power, amplitude, speed and pressure)
  • Seam distances resp. operating cycles can be programmed (sequence welding)
  • Reproducibility of the welding process
  • The energy adjusts to the speed (via a pedal) = Dynamic welding
  • Equipped with differential feed; separate drive for sonotrode and anvil wheel; that means smooth, non-distorted seams or the possibility of adding a some fullness
  • Process reliability through monitoring of welding parameters with integrated device for constant performance (so that reliable processing is possible even when sewing over cross seams)
  • Possibility of spot welding (tacking)
  • No start/stop – marks
  • Touch screen (simple handling with pictograms). Touch-control-panel P1 with integrated SD card reader and USB slot
