Cast carbon film for car styling has to withstand a great deal – the material is therefore thick, sturdy and flexible all at once. This poses a real challenge when it comes to slitting it on a roll. In our material test, we show how the NEPATA slitter performs in this regard.

The result: straight, clean cut edges

The photos speak for themselves: the cut edges are perfectly straight and clean, with no fraying. The key to this is choosing the right blade for the job. Particularly when working with tough materials such as carbon film, the 5 mm blade with a double-edged grind and the solid carbide blades deliver particularly good results.

Lubrication system and line laser

Two further features of the carbon film help to ensure a clean finish:

  • Pad lubrication system: It evenly coats the blade with silicone oil, thereby reducing friction and heat build-up.
  • Line laser: This enables the slitting blade to be positioned with precision.

The following video shows how the automatic lubrication system works.
