Batteries and Energy Storage
Batteries and Energy Storage Systems
We precisely tool our machinery to process the high quality materials required for the manufacture of batteries including lead acid, lithium and other various types packaged in cylindrical, prismatic or pouch cell configurations. We can combine mechanical cutting, permeation, and high strength sealing processes to ensure reliable cells are manufactured with precision at rapid production speeds.

Flexible vs. Solid Rotary Dies. What’s the Difference?
There are two types of rotary dies: flexible and solid. Rotary die cutting involves either a flexible or solid rotary die. These dies are both cylindrical dies. A flexible die is made of a thin sheet of steel, and wraps around a magnetic cylinder. A solid die is a solid steel cylinder, and is traditionally used in more long run applications for extended die life. Bernal develops solid rotary dies for converting and product manufacturing applications throughout many industry sectors.
Bernal invented the solid hardened rotary die in the late 1960s by creating a wedge-type cutting edge on a solid cylinder through the use of EDM (electric discharge machining). Our proprietary process allows us to precisely manufacture dies, thereby...read more
Rotary Die Cutting is a precise process that uses a die to cut rolled or sheeted material such as plastic, rubber, foil, cloth, paper, foam, and many others. This is a manufacturing process that cuts uniform shapes out of materials to create both component...read more
Bernal Rotary Die Cutting is essentially a process that can cut or form materials into virtually any shape. Technological developments have expanded the processes that a rotary die configuration can perform. Die cutting is a primary go-to process in the material...read more
