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.
Creasing is an operation which facilitates the folding operation. During this process, the paperboard is weakened along well defined folding lines, which then act as hinges for folding packaging and graphical products. Without creasing the surface, plies...read more
Bernal RP® rotary dies represent a breakthrough technology in the folding carton industry for solid rotary tooling. These dies provide significantly longer die life over conventional rotary dies while maintaining cutting quality and minimizing waste by...read more
Bernal invented the solid hardened rotary die in the late 1960s by creating a wedge-type cutting edge on a solid cylinder through the use of EDM (electric discharge machining). Our proprietary process allows us to precisely manufacture dies, thereby...read more
