Bernal Rotary Dies

What Bernal Rotary Dies does

Bernal Rotary Dies, operating legally as Komori Chambon USA Corporation, designs and manufactures precision rotary die-cutting and web converting systems for high-speed continuous manufacturing. The company serves enterprise manufacturers across folding carton packaging, beverage carriers, battery and energy storage components, consumer products, tobacco packaging, liquid packaging, food processing, medical devices, automotive, aerospace, and industrial manufacturing. Its core technology centers on two proprietary rotary die platforms: RP Rotary Dies with shearing blade technology that eliminates metal-to-metal contact and extends die life, and Crush Cut Rotary Dies pioneered by Bernal in the late 1960s using Electrical Discharge Machining (EDM) to produce a wedge-type cutting edge with .001" accuracy. The product portfolio extends from individual dies (3" to 40" diameter, supporting 10 to 500+ million revolutions) to complete converting systems spanning 1" to 110" web widths at speeds up to 1,500 fpm, including folding carton systems delivering .005" registration accuracy and 10-minute changeovers.

The company operates a custom-engineered, build-to-order business model, selling one-time capital equipment licenses directly to enterprise customers through a dedicated field sales organization (VP of Sales and Services, National Account Manager, Senior Business Development Manager, Spare Parts Sales Coordinator). Revenue streams comprise custom converting systems, rotary dies, die cutting modules and cassettes, spare parts and aftermarket support, and engineering/R&D services including R&D Proof of Principle that frequently yields patentable designs. Pricing is quote-based with no public tiers, reflecting the engineered-to-order nature of the product. Bernal assumes full system responsibility from concept development through installation and commissioning, supported by in-house advanced machining (CAD/CAM, CNC, CMM, EDM), microprocessor-controlled drives, PLCs, production data acquisition, and integrated visual inspection with real-time quality control. System efficiencies are stated at up to 99%.

Bernal was founded as Bernal Rotary Systems in 1972 (the firmographic founding year), having pioneered solid-hardened rotary dies using EDM in the late 1960s. The company was acquired by Komori Chambon Group—a global printing and converting technology manufacturer founded in 1923—forming the Bernal Komori Chambon Group (BKCG). Bernal operates from a single facility in Rochester Hills, Michigan, with 51–100 employees, and serves Fortune 500 clients with installations worldwide.
