Flexible vs. Solid Rotary Dies. What’s the Difference?
There are two types of rotary dies: flexible and solid. Rotary die cutting involves either a flexible or solid rotary die. These dies are both cylindrical dies. A flexible die is made of a thin sheet of steel, and wraps around a magnetic cylinder. A solid die is a solid steel cylinder, and is traditionally used in more long run applications for extended die life. Bernal develops solid rotary dies for converting and product manufacturing applications throughout many industry sectors.
