Crush Cut Rotary Dies

WHY CHOOSE BERNAL INC. CRUSH CUT DIES?

Bernal Inc. invented the solid hardened rotary die in the late 1960's by generating a wedge-type cutting edge on a solid hardened cylinder using EDM (electrical discharge machining)…now a proprietary process. Since then, thousands of rotary dies have achieved high-quality cuts, at the highest speeds, in countless materials and products.

Examples: include folding cartons, disposables, medical bandages, printed circuits, batteries…even snack foods.

WHY CHOOSE BERNAL INC. RP DIES?

Bernal Inc. RP dies represent breakthrough technology in the folding carton industry. They provide significantly longer die life than conventional rotary dies, while maintaining like-new cutting quality. How can we do all of this? Through the use of "shearing" blades, instead of crushing blades, on both the upper die and the lower die.

The RP "shearing" action results in the very highest level of cut quality. Bernal Inc. offers a variety of RP die choices, including various steel alloys, several hardening techniques, and designs with and without journals. Whatever your needs, we have a die priced to generate the lowest cost-per-thousand for most carton volumes.

WHAT ARE THE BENEFITS?

RP dies, with their exceptionally strong blade design and long life, allow an operator to forget the die cutting part of the process and focus on other areas. Untimely damage to cutting blades can be repaired by Bernal Inc. repair department or by your own personnel, often in your own plant.
