Accessories I Retrofit

Acoustic protection hood


Rotate the image.

For small parts with sound-critical applications. The compact and space-saving acoustic protection hood reduces the sound level and is equipped with a safety lift door.

  • Reduction of sound emission in accordance with applicable regulations of the Noise Control Ordinance,
    Limit value: 80 dB(A)
  • Pneumatically driven lift door with one-hand start and safety guard
  • Front can be swung away for maintenance purposes
  • Can be used for component sizes up to max. 300 mm width and 250 mm depth

Film feed unit


Rotate the image.

For welds on visible surfaces. The film transport conveys unused film pieces between the sonotrode and the part, thus preventing damage or markings.

  • For protecting sensitive workpiece surfaces against marking
  • Can be selected or deselected in the control system
  • Individually adjustable to the workpiece
  • Pneumatic drive

Sliding table


Rotate the image.

For parts that do not allow direct placement under the sonotrode due to their geometries. The sliding table positions the part under the welding unit.

  • For placing high parts under the sonotrode.
  • The part size is limited by the sliding table
  • Stroke 125 mm
  • Can be selected or deselected in the control system
  • Clamping plate for plane-parallel alignment of the workpiece
  • Pneumatic drive
