PFAFF 8317i

Programmable single-head ultrasonic welding unit (steel or titanium sonotrode) with innovative material feed


The new 8317i are offered in two versions:

BASELINE:  The economical version - manual welding unit for short and not too large parts
SYNCHRO:  The efficient version - modern welding unit large parts up to 1,600 mm


Features (Baseline & Synchro)

  • Optimized machine setup with innovative material feed for processing pleated filters
  • Safe and efficient processing of different material thicknesses up to 3 mm and fold heights from 10 mm to 50 mm without retooling
  • Selection of different sonotrodes, depending on the application:
    - Titan sonotrode, 10 mm wide:  For processing thick materials
    - Steel sonotrode, 10 mm wide:  For the DUAL version, to cut off the protruding material
    - Steel sonotrode, 7 mm wide:  For large pleat heights up to 50 mm
  • Depending on the application, various anvil wheels (Ø 75 mm) and cutting wheels with different cutting angles (for the DUAL version) are available
  • Seam lengths can be easily programmed via the touch panel
  • Complete reproducibility of the welding processes
  • Pleasant, ergonomic ultrasonic welding frequency of 35 kHz (silent production)
  • Touch control panel (easy operation via user-friendly icons)
  • Differential feed: Separate drive for sonotrode and anvil wheel; that means smooth, non-distorted seams
  • Options: Seam cooling from above & Puller to support the feeding




Additional features of the Synchro:

  • Quick setup and changeover of machine settings (filter length, pleat depth, etc.)
  • New sliding table that works in sync with the welding process (self-propelled/differential work possible)
  • Standard sliding table sizes: 1,000 mm or 1,600 mm (others available on request)
  • After the welding process, the sliding table returns to its starting position
  • Automatic start and stop of the welding process (programmable)
  • Option: Ejector as removal aid


    Special version with tape feeder:

    • Adhesive tapes are fed reliably via the tape feed
    • This enables the joining of non-thermoplastic materials
    • The adhesive tape is positioned between the two end folds



    Application

    Processing pleated filters and similar articles
