There is a difference in lifespan and thickness. WILA protective foil is available in thicknesses of 0.8 mm and 2 mm. WILA protective cloth is made of a densely woven nylon cloth that is 0.3 mm thick. Protective cloth has a life cycle of as much as 8-10 times that of protective foil and is more flexible. Our advice is to use non-marking cloth.

Non-marking sheet or foil can be clamped onto the Bottom Tool Holder using our clamping system for K-003/4/5.

A non-marking synthetic insert is an insert that can be used inside bottom tools, type OZU-016, enabling you to bend without marking. Contact WILA for tailored advice.

Try to minimize friction. You can do this by using bottom tools with a larger shoulder radius. You can also opt for a larger V-opening, which will reduce the required tonnage. Note that this will also result in a larger bend radius and will require changing the flat pattern of the product. Lubrication will reduce friction but often requires more cleaning of both tools and products.

Rotabend will significantly reduce part marking, but it will not enable you to bend completely mark-free.
