Spin welding

Read process description

The REK-B offers all advantages of the high technical level of the OMEGA III series, particularly regarding precision and reliability. The machine may be integrated in an automatic production line and controlled via a higher-ranking control system (PLC).

Options:

  • Hydraulic oil brake
  • Working table
  • Housing
  • Light curtain
  • Rotary table
  • Control of external periphery

Advantages:

  • Easy programming via touch panel TP 700
  • Display of time-travel curve and pressure-time curve after the welding cycle on a graphic display with plain text.
  • Regulation of the welding forces via proportional valve technology.
  • Storage of 99 welding programs; all parameters can be called upon immediately.
