One of the challenges of bending is to prevent the profile of having bending marks, such as; scratches and abrasions on the surface areas.
Especially of Profi le made of:

• Stainless Steel
• Aluminium
• painted metal panels

It is often the case of a line building from the contact of the sheet metal with the die. This is the cause of friction of sheet metal on small radius. In order to prevent this markings, the following solutions are possible:

• Bending Foil
• PU-Upholstery
• Plastic Dies
• enlarged opening radius on special T-Dies
