Rolleri Mark-Free Bending

Prevention of Bending Marks

Prevention or Reduction of Bending Marks

One of the challenges of bending is preventing the profile from having bending marks, such as scratches and abrasions on the surface areas.
Especially of profiles made of:

  • Stainless Steel
  • Aluminium
  • painted metal panels

often show lines in the contact areas between sheet metal and die. This is the consequence of friction occurring when bending sheet metal with dies with small radius on the V opening.

In order to prevent this marking, the following solutions are possible:

  • Bending Foil
  • Polyurethane inserts
  • Synthetic Dies
  • Rolla-V
  • enlarged radius on the V opening of a die

The alternative to these options mentioned above,
is a modification of the dies:
