Benefits of LIMO's diode lasers for welding of polymer:
  • Process stability through industrial in-process-controls (pyrometer)
  • Process-optimized laser beam
  • Outstanding component access, even for complex 3Dshapes
  • Small heat-affected zone and non-destructive processing
  • Non-porous, bubble-free and consistent welding seam – even at high processing speeds
