In contrast to press brake bending, which usually leaves clearly visible pressure and scratch marks next to the bending line, metal folding can also be described as gentle forming. This makes a considerable difference in quality for parts with a demand on the optical finish. However, if upper beam tools with a radius are used instead of sharp tools, the sliding section of the folding beam tool on the material surface will be also longer. In such applications folding beam tools with a plastic insert avoid pressure marks on high-quality material surfaces.
- Bending of pre-coated sheets and stainless steel parts (sometimes even without protective film)
- The parts shown are bent with radius tools and without protective film
