Crush Cut Rotary Dies by Bernal

Why choose Bernal Crush Cut Dies?

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.

Key benefits of Bernal Crush Cut Rotary Dies

Bernal’s Crush Cut Rotary Dies are constructed from solid, high-hardness tool steel, designed to precisely cut continuous webs of material. With exacting tolerances, these dies ensure exceptionally clean cuts at high speeds, optimizing throughput.
