Product Description

Features:
  • Patented mechanical synchronization of the working tables; a novelty to achieve a homogeneous application of pressure in the weld seam area
  • Process forces regulated via proportional valve
  • Siemens S7 control system with 5.7" full graphics touch screen
  • Machine design based on a sturdy welded framework construction. All of the machine's components are matched to the relevant load case to ensure the top quality welding of plastics
  • Welding tables in composite construction to eliminate torsion stresses and provide stiffness
  • Pneumatics equipped with maintenance friendly valve clusters of the latest generation
  • Integrated and highly dynamic electronic heating element temperature control
  • Flexibility to end or stop the process times during the welding cycle
  • Robust and in the clamping bar integrated non-rotating clamping feet
  • High quantity of decoupled and anti-twist protected clamping feet in order to match perfectly to each sheet length
  • Highly flexible suspension of clamping feet for secure fixation of sheet adjacent to the welding area
  • Interpretation of the max. machines forces on an 8 bar compressed air supply
  • Ergonomic cleaning position for the heating sword
  • Ergonomic working table height
