Why Choose Bernal Crush Cut Dies?
Bernal pioneered the solid-hardened rotary die in the late 1960s, developing a proprietary wedge-type cutting edge on a solid-hardened cylinder using Electrical Discharge Machining (EDM). Since then, Bernal has delivered thousands of rotary dies renowned for high-quality cuts, exceptional speed, and compatibility with diverse materials and products—ranging from folding cartons and medical bandages to printed circuits, batteries, and even snack foods.
