New and Improved—Again

Started in the late 1940s as Bernal, Inc., the company manufactured punches. It wasn't until 1966 that the company, who is today known as a rotary die pioneer, even began to dabble in that technology. Seeing an immediate niche for itself and its new rotary EDM and rotary pressure (RP) cutting dies, Bernal ushered the era of rotary cutting into the folding carton industry. The EDM process allowed Bernal to put hardened blades in solid rotary steel cylinders by removing portions of the steel, leaving only the blade standing. Previous attempts at such a process resulted in distortion of the blades, rendering the die useless.
